More Evidence that the Moon Came from the Earth

Will et al. Indigenous noble gases in the Moon’s interior. Science Advances, Aug 2022.

Humankind has always been fascinated with the Moon and studying it for nearly five centuries since Galileo. A recent discovery now adds new evidence to the currently favored “Giant Impact” theory which hypothesizes that the Moon was formed by a massive collision between Earth and another Mars-sized celestial body around 4.5 billion years ago. A group of researchers examined six samples of lunar meteorites collected in Antarctica using an exceptionally sensitive mass spectrometer and found that the meteorites contained noble gases like Neon and Helium, consistent with those found in the Earth’s mantle. Researchers proposed two possible scenarios for how the noble gases became trapped in the Moon’s interior. In the first scenario, impactors got mixed with the lunar mantle during cooling of the magma oceans to solidify over few million years of the Moon’s formation. In the second scenario, the Moon has been formed from a debris field surrounding the Earth where noble gases were directly mixed into the Moon’s interior mass. Discovery of noble gases on the moon may also inform us about its water content, too. If these gases are still there, then water could also been present in the Moon’s interior. Such water resources could be an invaluable resource for future human missions. More broadly, this study suggests that a wide variety of life-forming material can survive giant impacts early in a planet’s life. We now could make more reliable models of how planets and solar systems form and even how life is originated on the Earth.

Restoring cell functions after death?

Andrijevic et al. Cellular recovery after prolonged warm ischaemia of the whole body. Nature, August 2022.

Organ transplantation is an extremely complicated medical process. There is a massive shortage of donor organs. Waiting lists are long. Even if a patient is lucky to match with a donor organ, getting that organ before it dies through cell damage has been a big challenge. A new technology may offer a solution to extend the time that donor organs survive. A group of researchers has recently developed a technology called OrganEx, which can restore cellular activity even after death. Very shortly after the death of an organism, all cells start to die and organs begin to fail. The researchers worked with one hundred pigs to see whether cellular structures could be saved, or cell damage could be reversed, when OrganEx is applied after death. OrganEx has two major components. First is a device that simulates the heart and lung function by pushing a mix of blood and a drug cocktail to the organs. Second is the drug cocktail made of 13 chemical compounds. One hour after death, the pigs were hooked up to the OrganEx machine which pumped the cocktail to the animal’s organs for six hours. The results were striking; OrganEx could restore critical cell functions after death. While this is a huge step for organ preservation, researchers still have to make more tweaks for the technology to be used in humans. Once fully developed, OrganEx is expected to keep organs outside the body for long-term or transported longer distances.

Sweat-powered wearable electronic devices

Liu et al. Microbial biofilms for electricity generation from water evaporation and power to wearables. Nature Communications, July 2022.

Researchers have developed a biofilm that sticks to the skin like a Band-Aid to harness sweat for electricity that could power wearable devices. The biofilm is made using a type of bacteria called “geobacter sulfurreducens” known for its ability to produce electricity. In this biofilm design, bacteria convert energy from evaporation into electricity by using the moisture on a person’s skin. Most strikingly, researchers found that the biofilm bacteria do not need to be fed because they are dead! They do not need to be alive to produce electricity. The biofilm consists of thin sheets of bacteria colonies (thickness less than 0.1 millimeter) that is sandwiched between two mesh electrodes and sealed with a soft, sticky biopolymer to enable it to grip to the skin. Sticking this biofilm on your skin is like plugging in a battery. This technology has potential to revolutionize wearable electronics by solving the major problem of power supply. Moreover, this is a real green energy-driven device made naturally by the microbes and devoid of any unsustainably produced materials and toxic waste byproducts. The current version of the biofilm can produce enough energy to power small devices such as medical sensors or personal electronics, but the researchers hope to explore larger films that can power even more sophisticated devices.

The dispersal of scent takes place via the thermal and light-like behavior of the fragrant particles in the air. Thousands of points, letters, and words are positioned in each and every air particle. Each molecule is created in a form to carry sounds, sights, and odor. Millions of sound waves, scents and images are being transported and translocated into each of the trillions of air particles without deforming or mixing. As our knowledge pertaining to this transport grows, new technological products that will enable the transport of odors will be offered to the service of mankind.

Our sense of smell occurs in the brain. The chemical molecules exiting a lemon peel stimulate the odor receptors in the nose, which are then transmitted to brain to be interpreted as electric signals. Our olfactory system can easily distinguish more than ten thousand scents. This has inspired scientists to design similar devices. These models are called “electronic noses.”

A series of chemical receptors are utilized in the electronic nose instead of the receptor proteins of the human nose. Each of these is designed to sense various scents. These devices are difficult to produce, as the cost grows for a more sensitive device. The signals that sensors collect from the environment are converted into binary codes via electronic systems and then sent to a computer. The role of human nerve cells in charge of sensing odor is replaced by the electronic systems of a computer.

Mostly in their early phases, electronic noses are beginning to be used in various sectors, primarily those involving foods and perfumes, as well as the medical and chemical industries.

How does odor transportation take place?

As I already mentioned, the aromatic molecules transported via air particles in their gaseous state are detected by the smell sensor system and converted into electric signals. Quite a few different materials are used as conductors: conductive polymers, semi-conductive metal oxides, a quartz-crystal micro-balance (QMB), surface acoustic wave (SAW) sensors, pellistors, and infrared sensors.

Once the electric signals are converted into binary, the odor information is determined via a software program in which algorithms such as artificial nerve networks and support vector machines are employed. This information is then transmitted to a remote medium via lines of communication, such as a computer network, the internet, or another form of mobile communication. The odor type is received in the target computer. This detection stage can be completed in the target PC when necessary.

Today’s technology can only permit the transmission of odor data. In order to perceive the transmitted information at the target location as smell, the scents must be present as stored in containers and must be triggered via received odor data to be dispersed. The research in this field is limited, with ongoing pilot studies.

How can diseases be diagnosed with odors?

The natural functions of the human body, such as sweat, blood, urine, and feces, can be used to help diagnose diseases. The odor of the gases in human breath holds significant information regarding body health. There are between two hundred and four hundred different gases found in human breath. Furthermore, the number of gas types detected and described in the breath can exceed three thousand. While blood gets cleaned in the lungs, the gases of the used blood pass to the breath via the alveoli. Therefore, many critical pieces of bodily information are present in the breath.

The gases exhaled through our breath are composed of various alkaline and aromatic compounds. Each of these is a potential indicator that provides information about a disease. The gases and their ratio in the breath of a healthy person are well established. Since the ratio of the gases in the breath gets altered depending on the cause of an illness – such as diabetes (Type I and II), cancer of the ear-nose-throat, tuberculosis, and women’s reproductive diseases – can be diagnosed by utilizing the electronic nose.

There are other uses for the technology, too. NASA is developing a highly sensitive artificial nose for space research. This device will almost be able to distinguish every type of chemical compound, making more sensitive measurements than a human nose. With this device, the detection of harmful substances in the space station will be possible.

Google has announced that significant progress has been made regarding the “Google nose” which helped revolutionize searching for aromas. The Google Aroma database (http://www.google.com.tr/intl/tr/landing/nose/) stores more than 15 million kinds of scent. The days when we will be able to smell the scent of any product through our internet based devices do not seem to be too distant. To make this possible, sound waves would be converted into odor signals. There is a partially-imaginary video prepared to show how this can feel.

New technologies will change our relationship with smell, which has always been deeply important to humanity. Reference is made of this in the Qur’an, especially when the Prophet Jacob of Canaan sensed the fragrance of his son, Joseph, who was hundreds of miles away. The verse, from the chapter of Joseph, reads, “Surely, I sense the fragrance of Joseph, unless you would consider me a dotard. “It shows how valuable scent is to us, as anyone who has had a long lost memory triggered by an unexpected smell understands. As the verse suggests, losing our sense of smell is akin to losing our minds. Research has borne this out, as one of the first symptoms of Alzheimer’s disease is the loss of smell. In fact, monitoring loss of scent has helped with the early detection and prevention of Alzheimer’s. This is yet another way that our body has been perfectly calibrated to cue us in to its messages. In this regard, as with many, technology is still trying to catch up to nature.

Only 0.15 % of the energy that reaches the earth is used by the plants and the algae as a source of energy for photosynthesis. The energy that is stored in the form of chemical energy within the photosynthetic plants establishes the source of energy for the food that is consumed by the creation. The past creation, as a result of the physical-chemical processes, was fossilized and solar power has been stored in the form of fossil fuels (oil, coal, natural gas).

Energy consumption and the environment

Energy consumption is viable for every form of work; the waste is what remains in the environment. This waste does not pose a problem as long as they do not damage the sensitive ecologic balance. However, rapid industrialization and urbanization, which lead to excessive amounts of energy consumption, result in environmental problems. Since industrialization-urbanization is directly related to energy consumption – particularly with fossil fuels – industrialized countries are more vulnerable to experiencing environmental problems. In today’s world, it is climatic change – a product of global warming – among these problems that is of the greatest global importance.

The increase in the proportion of carbon dioxide, a greenhouse gas, in the atmosphere is the main factor for global warming. This increase is directly related to the consumption of fossil fuels. The rays of the sun, which are reflected from the earth, are trapped by carbon dioxide gases (chlorofluorocarbon, nitrous oxide and other greenhouse gases, such as water vapor) in the atmosphere, and they can not return to space. This, in turn leads to the atmosphere heating up (the greenhouse effect), eventually leading to an increase in heat throughout the world.

The main reason for the increase of carbon dioxide in the atmosphere is the consumption of fossil fuels (77%) and the decrease in the number of forests (23%). Coal gas is normally the last product of the anaerobic processes in nature. In recent years human intervention played the main role in this abnormal increase in gases. Playing an important part in this process is the expansion in rice fields (38%) in order to feed the increasing population, natural gas extraction and its transfer (16%), an increase in the number of cattle (14%), coal mining (12%), and the oxidation of produced biomass (6%). Chlorofluorocarbon is included in industrial products. As for the nitrous oxides, they are the by-products of reactions in the nitrogen cycle in nature. In recent years, as a result of the increase in the use of the nitrogenous manures (85%), forest fires and other fires (11%), and the oxidation of the produced biomass (7%) there has been a rise in nitrous oxide. Consequently, the rapid increase in greenhouse gases in the last years has lead to a 0.5°C increase in the average heat of the earth.

If the greenhouse gases continue to be accumulated at this speed, then by 2100 the average heat of the earth will record an increase of 2–4°C compared to the period before industrialization. Eventually, there will be a greater melting of the glaciers at the poles, which will lead to 0.5–1.5 % increase in sea level. Thus, residential areas by the seaside, agricultural areas, wetlands and industrialized areas will face the danger of being flooded. Moreover, the risks of climatic changes and desertification will become much more severe.

Some countries are investigating how to calculate the probable effects of a decline in water, food and energy resources and what precautions need to be taken accordingly as a result of global warming. In this sense, the problem was clearly indicated during the summit meetings in Vienna (1985), Rio (1982), and Kyoto (1997), however, they have not been sufficient to provide a solution.

Another important problem arising from the overuse of fossil fuels is the damage to the environment caused by air pollution and acid rain. During the consumption of fossil fuels, CO2, NOx, and SOx are emitted into the atmosphere and these, combining with water vapor, lead to the formation of carbonic acid (H2CO3), nitric acid (HNO3) and sulfuric acid (H2SO4). While normally the pH of rain water is 5.5–6, with these acids it falls down to 3.5–4. This and the resultant dissolution of the metals in the water pose a threat for both the land and the aquatic ecosystems (e.g. a decline in fish species in many lakes) and impair the ecologic balance.

The impact of alternative and renewable energy on the environment

The negative impact of fossil fuels on the environment and the decline in their reserves has accelerated the search for new energy resources. Even though nuclear energy is not a renewable resource, today it has come to be regarded as an alternative energy resource all around the world. Hydrogen, too, is another growing alternative resource. Geothermal energy is also a renewable energy resource, yet it is mostly restricted to the region where it originates.

With current technology, it costs us more to use solar energy rather than to extract fossil fuels. Moreover, there is a great need for the development of new technology that is aimed at producing wind, hydroelectric, bio-energy, tidal and wave energy in the most efficient way at the lowest cost.

Defeated by their ambitions, human beings, particularly in the last century, have destroyed the world and the environment that has been entrusted to them. Since the global impact and the cost of this process only emerged recently, it was too late before human beings realized that they needed to shift from energy systems based on fossil fuels. All the worries and concerns that have surfaced today is not because we have finally realized that the earth has been entrusted to human beings, but simply because the future seems to be promising nothing but destruction. Thus, the real solution to the problems is not related to acting to find a solution to the problems, but rather in being in compliance with the measures of the actual Owner of the world and the universe and avoiding form all types of extremism.

Thus, the nitrogen molecule is inert and stable. However, in spite of this fact, nitrogen molecules undergo oxidization in the presence of water; in other words, nitrogen molecules are unstable in the presence of H2O and more easily form other compounds. This is expressed in the following equation:

This reaction occurs quite slowly. If this reaction did not occur so slowly, all of the nitrogen and oxygen molecules in the atmosphere would immediately combine with ocean water to form nitric acid. If this were to occur, an extraordinarily terrifying scenario that would lead to a global catastrophe would occur: The earth’s oceans would change into nitric acid, the most powerful and harmful acid in both its oxidizing and its acidizing effects! Such an event would entirely consume the nitrogen and oxygen of the atmosphere. The only more devastating global calamity imaginable is the apocalypse and the end of time itself! Of course, this chemical reaction cannot be entirely eliminated, even if its rapid occurrence would result in a terrifying global catastrophe. On the contrary, this chemical reaction must continue to occur slowly, as it has in the past, in order to ensure the proper formation of nitrogen compounds in the chemistry of the ocean; this is crucial to the continuation of life on earth. It is interesting that this phenomenon can show us how misguided some philosophers and philosophical movements, who have not based their thinking on religious principles, are in their attempts to demonstrate that humankind is God-like.

Although humankind is the most perfect creation in the universe, we are nonetheless almost entirely helpless in the face of the dangers that threaten us. The chemical reaction, summarized briefly above, has been taken from a basic chemistry textbook. The rate of the chemical reaction we described-in which nitrogen molecules in the presence of water can result in oxidation and the formation of nitric acid-in fact occurs in such a measured way that it is beneficial rather than harmful. This fact, along with the regularity at which the rate of this reaction occurs, clearly demonstrates the helplessness of the human condition.

Fortunately, the slow rate at which this reaction occurs ensures that the terrifying global catastrophe described above does not occur. Entire oceans do not turn into nitric acid, and the oxygen and nitrogen in the atmosphere, which is so crucial to our survival, is not consumed in this apocalyptic fashion. Should we not, therefore, learn the chemistry behind this good fortune? Even more importantly, should not we wonder Who calibrates the rate of this reaction, and continues to ensure that this careful calibration is not disturbed?

Greenhouse Gases and the Greenhouse Effect

A greenhouse is a place that is usually covered with glass or plastic walls where early season vegetables and house-plants are cultivated. Rays from the Sun can easily penetrate a greenhouse, but once they hit the ground they are transformed into thermo-energy, with the wavelength of the beams shortening and their energy diminishing. As a result, these beams with a shorter wavelength cannot leave the greenhouse due to the glass or plastic walls. Therefore the warming of the greenhouse increases as more and more rays enter. We call this process the greenhouse effect.

Similarly, some gases in the strata of the atmosphere are called greenhouse gases since these gases cause the same greenhouse effect for the Earth. These gases include carbon dioxide, methane, nitrogen oxide, ozone, chlorofluorocarbon, and water vapor. These gases have been created with a property that does not prevent (or prevents to a very small extent) the light energy that comes from the Sun from reaching the Earth and that prevents the infrared heat energy waves that are formed after this energy reaches the Earth from radiating to the higher layers of the atmosphere. Both the Earth and the layers of the atmosphere close to the Earth are heated by these gases. If there were not any of these gases surrounding the Earth it is estimated that the Earth would be 33° C colder. Although there is a delicate balance and measure among the gases in the atmosphere that allows the maintenance of the Earth’s temperature at a sensible level, human beings are carrying out practices that can ruin this balance. We, as human beings, are responsible for the global warming that is perceived as a danger today.

Carbon Dioxide

Carbon dioxide is half the reason for the total greenhouse effect. This gas is formed as a result of the use of fossil fuels, the respiration of humans, animals, and plants, and the disintegration of organic substances. Industrial development has caused a rapid increase in carbon dioxide in the atmosphere. It is known that 85% of the carbon dioxide emitted into the atmosphere comes from fossil fuels, with 15-20% stemming from the respiration of living beings and the other ecological continuous cycles.

In the last 150 years, a total of 389 Gt of carbon dioxide has been emitted into the atmosphere. 265 Gt of this carbon dioxide comes from the consumption of fossil fuels and the production of cement. 124 Gt comes from changes in land use. 214 Gt of this total has been reabsorbed by land and sea ecosystems and the oceans. This means that there is a surplus of 175 Gt of carbon dioxide in the atmosphere.

The Importance of the Forests

Forests play an essential role in lowering the diffusions of greenhouse gases that are emitted into the atmosphere and in forming “carbon absorption” by occluding greenhouse gases in the atmosphere. Thus, except for sedimentary rocks, 67% of the carbon kept on the land is stored in the forest ecosystem. 75% of the carbon kept by vegetation is stored in the forests. In addition, as long as some long-lived wooden products (wooden houses, furniture, etc.) decay or are burnt they remain as carbon storages.

As we all know, during photosynthesis the carbon dioxide that is taken from the atmosphere is separated into carbon and oxygen molecules. Then the carbon is stored in the roots, trunks, branches, and leaves of plants, being used in order to form carbon hydrates. Therefore carbon dioxide, the most essential greenhouse gas, becomes balanced. We can compare this to a huge factory that works very quietly and causes no waste. It is such an efficient factory that it transforms harmful substances into useful ones. We cannot say that we human beings appreciate this factory or protect its resources. Although today forests cover 3.7 billion hectares, comprising 30% of all land, between the years 1990–2000 on average 9.4 million hectares of forest were annually removed. That means that during this period the forest regions of the world diminished by 2%. As a result of such negative occurrences, because the carbon balance of vegetation, soil and organic substances had been destroyed, the forests, one of the means of God’s mercy upon us, have become sources of carbon dioxide and a tragedy due to our exploitation.

Ligneous living masses increase each year, while falling leaves add to the carbon storage. As a result, forest ecosystems contain carbon. After the growth of trees, most of the carbon dioxide they occlude each year goes toward developing the biomass of the tree. This means that in the first 30-40 years a high rate of carbon storage occurs. As the forest ecosystem develops, the organic substance of the soil and the total respiration in the ecosystem (occlusion of carbon dioxide) increase. When the ecosystem has fully developed, it no longer has the characteristics of “carbon absorption” anymore. In this case, the amount of carbon taken from the atmosphere is equal to the carbon emitted back by the biomasses of the trees and is kept in the soil. The time it takes for a tree to fully develop depends on the type of tree and the climate zones. However most of the carbon storage occurs in the first 60-100 years. It has been determined by research that a well-developed 100 year-old beech tree absorbs 40,000,000 m_ of air with its leaves for photosynthesis and binds 1,200 m_ of carbon dioxide in the air as 6 tons of carbon.

As well as being a community of trees, forests are environmental systems and living communities, with soil that was created over a thousand years, with millions of plants, animals, and microorganisms, and their reciprocal relationships. It is very difficult for this system to be restored once destroyed by human beings. Forests provide an essential service in a consistent and balanced carbon flow between the biosphere and the atmosphere with respiration that is dependent on photosynthesis and the activities of life in the soil and the plants. Forests are the lungs of the Earth.

In the light of these facts, the duty of human beings is to protect the vegetation and to reforest the treeless lands, to decrease human pressure on existing forests and to improve forests that have been damaged. Oxygen, nitrogen, water vapor, and carbon dioxide were created as continuous cycles for the continuation of the life. When these treasures have been damaged as a result of the greed of human beings, the costs are too high for us to reverse the trend. Billions of people are victimized; yet they are nor directly responsible for such acts. These delicate balances can be revived if we lead a simple and modest life, where we consume less and we produce less. Those who ought to understand this first must promise to be more respectful to God and to change themselves. Even if we fulfill our responsibilities, we can do nothing today but hope that those whose destructive powers are great may desire such a spiritual revolution.

In our world, the most practical solutions exist for the most complicated matters; the simplest things have important duties and splendid mechanisms are developed from these to carry out the same. Thanks to these mechanisms, there is a moderate climate and there are ideal values of air, pressure, heat and precipitation. Let us briefly consider a few of these systems that contribute to maintaining the average temperature in the world. The exact amount of solar energy we need reaches the Earth, and the distance between the sun and the earth plays an important role in this. If we think about the freezing cold on Mars, which is farther away from the sun, or the burning heat – a heat which melts even lead – of Venus, which is nearer to the Sun, we can appreciate the special status of the Earth and how carefully chosen its position is. If the solar energy that reaches the Earth were to decrease by only 10%, the average temperature of the Earth would decrease, and subsequently our planet would be iced over with an ice layer measuring a couple of meters in depth. A slight increase of solar energy, however, would burn everything and eradicate life on Earth. 

We should not ignore the fact that our planet is of such a size that it is able to keep its gases within the atmosphere in ideal amounts and proportions. Our planet could have been created as small as Mercury (1/8 the Earth’s size) or as big as Jupiter (318 times bigger than Earth). A smaller planet with lower gravity would disperse gases into space and therefore would have no atmosphere. A bigger planet would keep all the gases within the atmosphere, including poisonous gases, due to its high gravity. Furthermore, the Earth would be uninhabitable due to high atmospheric pressure and density. The fact that carbon dioxide and water molecules are scattered throughout the air in sufficient amounts means that they absorb heat from the sunlight during the daytime, thanks to their highly absorbent potential. At night, when there is no sunlight at all, the air keeps the previously absorbed heat in, just like a greenhouse, preventing it from being released into cold space. During the day, the atmosphere serves as a curtain protecting the world from the harmful effects of the rays of the sun; at night, it serves as a blanket preserving the heat. Devoid of such a protective shield, the moon is scorched by the rays of the sun during the day and it freezes at night.

Do we owe the small difference in temperature between day and night only to the gases in the atmosphere, which function like a thermos flask? Of course not! We can observe that the time span (24 hours) in which our world completes its rotation is so perfectly adjusted that the difference in heat is kept at a minimum. If the nights were longer, the Earth would get too cold; if the days were longer, it would become too hot. Mercury, rotating very slowly, is a good example, the heat difference between day and night can reach up to 1,000 degrees.

Seas constitute one of the systems which help to adjust the climate. At first, we may find it strange that seas cover a far greater area than land. We have named the planet that plays host to us “the Earth”. The word “earth” also means soil. However, most of the Earth’s surface (70%) is covered by water, not soil. Thanks to this reality, neither polar cold, nor boiling tropical heat prevails on our planet. The land, which is heated by the rays of the sun during the day, radiates the heat it has absorbed, just like a radiator. As for the sea, which is a huge mass of water, it only warms up a few degrees, despite the millions of solar calories it takes in. Nevertheless, once it warms up, it does not grow cold easily. The oceans, which cover a larger area than land, supply water to the land through evaporation, as well as serving as a thermostat that regulates the climate and prevents it from becoming too hot or cold. If the oceans were to occupy a smaller area, there would be less evaporation and less precipitation; the land would turn to desert.

The air that is heated by the sun rises to be replaced by cold air. In this way, low pressure centers appear where there is hot weather and high pressure centers appear where there is cold weather.

The tilting axis of the Earth plays a significant role in keeping the average heat within tolerable limits. On the other hand, the way the mountain ranges are arranged and the 100 difference in temperature between the equatorial and polar regions lead to the creation of winds. If such a heat difference were to appear on a planet that had an even surface, nothing would stand in the way of the storms, and they would reach a speed up to 600mph. The Earth however, is provided with natural barriers that block powerful air currents. These barriers begin at the Himalayas and continue as mountain ranges through the Taurus Mountains and the Alps, ending with the Atlantic Ocean in the west and the Pacific in the east. Another mechanism that helps regulate the heat in the atmosphere is that of the ocean streams. Overheating generated in the equatorial region is transferred to the north and south by the ocean streams, balancing the heat in different parts of the world.

This is not the only way in which the Exalted Creator Who has absolute control over the systems balancing the heat in the atmosphere manifests His Power. He assigned the clouds a similar job. Hot weather causes evaporation, which leads to formation of clouds. Clouds prevent some of the sunlight from reaching the Earth, reflecting it like a mirror.

The Proportion of Gases

The atmosphere consists of approximately 77% nitrogen, 21% oxygen, and 1% argon and other gases. The majority of living organisms, including human beings have been created with a metabolism that needs oxygen. When carbon compounds react with oxygen, the outcome is energy, with by-products being water and carbon dioxide. When such a reaction takes place in our body, the energy obtained is transferred to the energy packs (tiny accumulators) called ATP, which we use in our cells. Since all metabolic activities require ATP energy, we constantly need oxygen and this need is met through respiration.

Given that oxygen is a vital substance for us, we might think that it would be better for us if there were more oxygen in the atmosphere. Fortunately, our Lord did not create the universe in accordance with such simple logic. It is estimated that every oxygen increase of 1% over a level of 21% will also increase the possibility of forest fires by 70%, owing to the high inflammability of oxygen. An oxygen rate over 25% would cause the majority of our greenery to be burned to ashes. All the tropical forests and arctic tundra would be destroyed and it would be impossible to prevent great fires. This all goes to demonstrate that the present oxygen rate in the atmosphere is at equilibrium.

In spite of constant consumption, the rate of oxygen and carbon dioxide in the atmosphere is maintained thanks to a wonderful transformative mechanism which runs smoothly without failure (that is if we do not damage it). While animals consume oxygen, they continually release carbon dioxide into the atmosphere; carbon dioxide is a poisonous gas for animal life. Plants however, perform just the opposite activity, transforming carbon dioxide into oxygen, and producing nutrients as well, the most common being sugar. In this way, billions of tons of oxygen are produced and released into the air everyday.

What if plants, like animals, were to carry out the same reaction, consuming oxygen and releasing carbon dioxide? In a short time, our planet would turn into an uninhabitable place. We would use up the oxygen in the atmosphere in a short time and all life forms would be eradicated. And how about a world where both animals and plants produce oxygen? The atmosphere would have such a flammable quality that even the tiniest spark would cause great fires.

Like the other gases in the atmosphere, oxygen is kept at an ideal rate, its benefit and harm being precisely balanced. This is nothing more than the result of a perfect adjustment made by ‘Him’. There can be no coincidence in such splendidly created systems and nor can these things happen on their own.

A Breath of Air

The fact that the density of the atmosphere is ideal for respiration also indicates the impossibility of ‘coincidence’ in this delicate arrangement. No matter whether we feel it or not, we continue breathing every moment of our life.

We constantly inhale and exhale the air. The reason why we need to breathe so much is that there are billions of biochemical reactions taking place in our body all the time which can only be realized with oxygen. Oxygen is even helping you to read this article, for the millions of cells in your retina need to be supplied with oxygen. If the oxygen rate in your blood decreases, your vision blurs. All the cells that make up the muscles in our body have energy generating centers which function by burning carbon; in other words, they react with oxygen.

When we inhale, nearly 300 million tiny spherical bags (alveols) are filled with high-pressure oxygen. The oxygen in the capillaries that cover the cell walls is reduced and then is at a low pressure. This allows the oxygen in the air to be absorbed by the capillaries and to be carried away by the hemoglobin found in the red blood cells – the magnificent servants of our body. Then it begins to serve our entire body, starting with the heart.

The red blood cells which travel to the lungs from different parts of the body carry oxygen from the lungs to the energy centers of the cells and they carry the waste material – carbon dioxide – back again to the lungs. In this process, clean air (with oxygen) is inhaled and is exhaled with carbon dioxide. Obviously, both inhalation and exhalation are vital functions for which we should be thankful. The words we utter can be considered the fruit of the carbon dioxide we exhale. On the other hand, this waste gas is recycled into oxygen and sugar by plants.

The fact that 300 million tiny bags in our lungs have been constructed to fit into a limited area clearly indicates God’s infinite knowledge and the fact that He is Omniscient. If these were to be spread out over the ground, they would cover an area as big as a tennis court. They should, logically, require a gigantic organ to carry them; think about how we would carry this organ around with us…

In spite of being so tiny, the alveols and alveolar tubes in our lungs are large enough to let air move freely, which is another sign reflecting His wisdom.

The atmospheric pressure at sea level is 1 atm. This means that 1 kilogram of pressure is applied over a square centimeter, an area that is only as large as the tip of one’s finger. At sea level, 1 liter of air weighs 1 gram. As it is seen, the air has an immense pressure, in spite of its lightness.

The fluidity of air is fifty times greater than that of water. As a matter of fact, these values are very accurate and the fact that they are so is critical for our life. If the density of the atmosphere were to be slightly increased, breathing would become as difficult as sucking honey through a straw. Do not even think of saying “make the straw wider”, i.e, making the alveolar tubes in our lungs wider. In such a case, the area contacting the air would be diminished and the lungs would be unable to receive a sufficient amount of oxygen to meet the needs of our body. The resistance of the air would be too great and it would be impossible to design a respiratory system capable of supplying the oxygen we need.

Several conditions that make life possible are only realized at certain values, and the atmosphere possesses precisely all of these values. All these only go to show how delicate His adjustments are.

What if the atmospheric pressure was lower, for instance, just 20% lower than it is at present? Given that the conditions of evaporation and boiling depend on the air pressure, more water would evaporate from the oceans and eventually the high humidity of the atmosphere would create a greenhouse effect on the Earth. In other words, there would be excessive heat in the world. And if the atmospheric pressure was twice as great, the humidity would be so low that there would be terrible drought, turning almost all of the land into desert.

Several conditions that make life possible are only realized at certain values, and the atmosphere possesses precisely all of them.

Who are all these things balanced for?

The air that is in front of our nose, ready to be of use to us, the ground under our feet, the night and day that follow one another in succession… the sun, the honey bee covering miles for us… When we contemplate all these, we realize that all their activities are directed to serve us.

The beings in this universe do not serve us from their own free will. It is crystal clear that all things point to a Creator Who takes care of us.

Our Creator has bestowed us with ears, providing the world of sounds for us. He has created a brain in our skull, a heart in our chest and a tongue in our mouth; these serve as devices by which we sense and appreciate His blessings that overflow from His treasures of Mercy. He has presented various fragrances, tastes and colors for our senses; He has created numerous species in order to help such devices fulfill their true duty. Only the atmosphere and what it covers will suffice as signs that indicate the ultimate truth. Study the following Qur’anic verse, that reminds us of the divine grace: “And He subjected to you what is in the heavens and the earth all together, (as a grace) from Him.” The rest of the verse counsels us to reflect: “There are in that signs for a people who reflect.” (45:13)

And We have made the heavens as a canopy well guarded: yet do they turn away from the Signs which these things (point to)! (Qur’an 21:32)

We are often awed by how fine-tuned our planet is for the existence and continuation of life. One factor that makes this possible is its atmosphere, which is designed to filter out harmful radiation and meteors from space. While solar radiation is largely absorbed, some is reflected by the planet and the atmosphere. Some of the radiation reflected or emitted by Earth passes through the atmosphere, while the rest is absorbed and emitted in all directions by some gases in the atmosphere. This reflected radiation, combined with the energy absorbed by Earth, enables life to exist here.

Since this phenomenon resembles the heat reflected by glass panels in a greenhouse, it is called the greenhouse effect. The greenhouse gases that contribute significantly to this process are carbon dioxide, methane, water vapor, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride. The greenhouse effect is necessary for life, but too much of it is undesirable. Some negative consequences are changes in average temperature, precipitation, wind and ocean circulation patterns, polar glacier melting, and more storms, droughts, and floods.

The atmosphere is an extremely complex system that is not fully understood. During Earth’s long history, its atmosphere’s composition has experienced natural variations. By analyzing tree rings and core samples taken from Greenland and various high-altitude tropical areas, scientists have concluded that Earth has undergone several warming and cooling cycles. Among the factors that can cause such changes are greenhouse gases and ocean water salinity. According to Stant: “Since 1861 the Earth has warmed by about 0.5 degrees Celsius. Most of this warming took place before 1940, but much of it has taken place in the last 15 years. The global temperature of the Earth is projected to rise anywhere from 0.8 to 2.6 degrees Celsius in the next thirty to forty years.”1

Some scientists think that the most recent atmospheric changes are part of a natural variation. But there is a growing consensus that human activity, particularly the emission of greenhouse gases and especially the carbon dioxide produced by industrial activity, has played some role. Small amounts of such gases can be absorbed by forests and oceans, and thus do not represent a serious problem. But thanks to the Industrial Revolution, this system has been thrown out of balance. Other activities, such as increased agriculture, deforestation, and the widespread use of fossil fuels for transportation, industrial processes, and heating fuels have exacerbated it.

This article will summarize the latest findings on the potential impact of global climate change.

Background

The vast majority of scientists now agree that business-as-usual may lead to irreversible change in Earth’s atmosphere. Global climate change became part of the political agenda in the developed world during the mid-1980s, a time of increasing environmental awareness and mounting public concern due to the efforts of Greenpeace, the Sierra Club, and other pro-environment groups. One assumption gradually emerged out of the numerous conferences, grassroots efforts, and publications: The developed countries are primarily responsible for the accumulation of greenhouse gases in the atmosphere, and therefore should take the lead in fixing the problem. The latest step taken to mitigate worldwide emissions was the Kyoto Protocol (11 Dec. 1998), which devised a formula to determine the amount of gases each country could emit. Although signed by 84 countries, it has to be ratified by at least 55 countries (emissions from which make up at least 55% of global emissions) before it can be enforced. This has not happened yet.

The United States, the major producer of greenhouse gases, has signed but not ratified the Kyoto Protocol. Hopes were high that the new Bush administration would do so. However, Bush soon reneged on a campaign pledge to regulate carbon dioxide emissions from U.S. power plants, and shortly thereafter repudiated the Kyoto Protocol. His claim that the scientific evidence for the greenhouse effect and its consequences was not yet convincing was greeted with disbelief. Questions were raised about corporate America’s role in forming his views, as many companies opposed the protocol and contributed heavily to his presidential campaign.

Fortunately, there is also mounting evidence that industry opposition, led by the oil, gas, and automotive concerns, is weakening. According to the Natural Resources Defense Council, “many businesses recognize global warming as a threat and realize that reducing emissions is in their economic interest. Several-including such giants as BP-Amoco, IBM and Johnson & Johnson-have voluntarily adopted emissions reductions stronger than those called for in the Kyoto Protocol.”2

The Intergovernmental Panel on Climate Change

The World Meteorological Organization (WMO) and the UN Environment Programme (UNEP) established the Intergovernmental Panel on Climate Change (IPCC) in 1988. Tasked with assessing the scientific, technical, and socioeconomic data needed to understand the risk of human-induced climate change, its mission is to provide policymakers with the most current scientific data on global climate change. The IPCC serves as a good example of how scientists from different backgrounds and countries come together to investigate a global problem. Some of its findings are summarized below.3

Agriculture and Food Security. In principle, increased levels of carbon dioxide should benefit agriculture. However, one has to consider subsequent regional changes in rainfall and the reaction of crops, soil, and pests. Moreover, excessive heat and drought might have a negative impact on crop yield.

The overall effect on crop yield is predicted to be positive, especially in such colder regions as Canada and Russia, if the rise in average temperature does not exceed several degrees Celsius. If it does, the effect will be negative. In tropical regions, where crops are already near their maximum heat tolerance, even a minimal increase in temperature is predicted to have a negative effect on crop yields. The number of people at risk of hunger, especially in Africa, is expected to increase. The most vulnerable populations will be those who depend heavily on agriculture and those living in developing countries.

Ecosystem Damage. Ecosystems react to climate changes much slower than people. Wildlife habitat distribution and composition will be directly influenced by any change in temperature and rainfall, and indirectly by any change in vegetation. Most likely, species will not have enough time to adapt. This will be exacerbated by the continuing fragmentation of wildlife habitats by human settlement, which makes migration infeasible for most species. Since migration is unlikely, species composition and dominance will change, and endangered species will face extinction. Changes in ocean circulation will affect fish abundance and habitat boundaries, as well as fish population dynamics. This might have a significant impact on fish-dependent societies.

Rising Sea Levels. This is perhaps the most worrisome impact category. The IPCC Working Group I reports that as a result of melting polar glaciers, the global sea level will rise anywhere from 0.09m to 0.88m. Oceans cover a large part of the planet and have a significant impact on its climate. Wind and circulation patterns also are affected by changes in sea level and sea-surface temperature.

If the rises are high enough, many of the generally accepted models indicate that small islands will be submerged, many coastal areas will be inundated, and freshwater resources will face seawater intrusion. In addition, large coastal areas will be evacuated, populations will have to migrate, and wetlands and mangrove forests will be lost. Such countries as Bangladesh, which depends heavily on mangroves, will be devastated. The fishery industry will suffer as fish abundance and location change.

And, as if all of this were not enough, there also might be a rise in the frequency and severity of storms and sea-surges. Countries that depend largely on coastal tourism will suffer. Although people will see the approaching catastrophes and try to protect themselves by building seawalls, nourishing beaches, and other measures, not all of the impact will be cancelled.

Health Sector. There will be fewer complaints about the cold during the winter, but more complaints about the heat during the summer. Whether the benefits will outweigh the costs depends on the region. Tropical regions will face more deaths from heat stress. In addition, the influence areas of vector-, food- and water-borne diseases will shift. For example, depending on changes in rainfall and average temperature, malaria or dengue fever might become more widespread.

Although the specific impact depends on a wide variety of local conditions, such as the health infrastructure and socioeconomic conditions, the overall effect is predicted to be negative, especially in developing countries. Such extreme climate-related events as cyclones, floods, and droughts might become more common and severe, and thus leave exposed populations with even more health problems.

What Needs To Be Done

For each anticipated impact category (and for others not included here),

there is a wide range of institutional, technological, and behavioral adaptation measures that can be pursued to minimize damage. The IPCC report contains many suggestions. Governments should become aware of the consequences of global climate change and start working to increase public awareness. As most measures might take decades to plan and implement, any delay only makes the problem harder to solve.

In addition, greenhouse gas emission rates have to be decreased. The time for playing around has passed. Governments and people in positions of power, as hard as it might be, should agree on a global approach and then set about implementing it. There have been some advances, but not enough. Developed countries, having caused the global warming problem, should take the lead in implementing the Kyoto Protocol as soon as possible.

A key ingredient is technology transfer. Most developing countries are still building industrial, energy, and distribution infrastructures. Developed countries should try to ensure that only the latest and cleanest technologies are installed so that the solution is not only postponed to a later date.

This is vital in China, now home to almost one-fourth of humanity and undergoing rapid economic growth and development. Given its size, its development policies will have a global impact. According to Mark Hertsgaard, who spent 6 weeks in China studying this issue: “China is … the world’s second largest producer of greenhouse gases, trailing only the United States. With its immense coal reserves, huge population, and booming economic growth, China is very likely to triple its greenhouse emissions by 2020 …. If outsiders want China to do something about global warming, they will have to pay for it. As one Western consultant with regular access to senior Chinese officials puts it, “They know very well they can hold the world for ransom … and whenever they can extract concessions, they will.”4

Many people in the developing world might object to “hold the world for ransom” for a quite logical reason: When the now-developed countries were developing, environmental damage and pollution were non-issues. Now that others are trying to develop, the developed world wants to maintain the status quo, which is stacked in its favor, by raising standards. This charge must be addressed in such a way that those making it will accept proposed environmental regulations and policies.

A Recent Development

On July 26, 2001, Japan and other nations joined Europe in accepting the Kyoto Protocol. But the price might have been too high: a scaling back of carbon dioxide reductions, the acceptance of “carbon sinks” (that forests and other environmental reatures would absorb more greenhouse gases), and that violators would not be penalized. President Bush has not yet revealed his promised alternative.

Conclusion

Global climate change, as the phrase indicates, is a global challenge that requires a great deal of attention and resource concentration. However, it also requires political will. This is especially true with China, which endured great famines and poverty during the twentieth century. Hoping to avoid any repetition, China has embraced the late Deng Xiaoping’s policy of “to get rich is glorious.” If it comes down to a choice between development and the environment, China and other developing countries just might choose development.

Western businesses claim that the developing world will gain an unfair competitive edge if its companies are exempt from existing environmental regulations. But instead of showing such countries see that environmental protection is in their own long-term interest and helping them acquire and implement the latest technology, many Western companies relocate in countries with lax and easily subverted environmental legislation. Such short-sighted policies increase the problem’s severity, for it shows that the developed world does not really care about the environment. If this is so, how can it expect the developing world to care about it?

Hopefully, nations will find a way to protect their environments while enjoying double-digit growth figures, and their scientists and politicians will find the necessary will to solve this problem

In the ongoing efforts of the United Nations toward that end, representatives from 50 countries participated in an informal international meeting convened by UNEP (United Nations Environment Programme), in conjunction with the Earth Council and the Government of Costa Rica, held 29-31 October in San Jose. Specifically, the meeting entitled, ‘New Partnerships to Reduce the Buildup of Greenhouse Gases, discussed cooperation through a range of issues related to the concept of ‘Activities Implemented Jointly’ or AIJ. Among those present were Elizabeth Dodeswell, the executive Director of UNEP, Mr. Maurice Strona, Chairman of the Earth Council, and Dr. Mostafa Tolba, Director of Inter-national Centre of Environment and Development. The forum was opened by the host, His Excellency The President of Costa Rica, Mr. Jose Maria Figueres.

The concept of AIJ (which appears to be a spin-off of the older concept of Joint Implementation) emerged in 1995 at the First Conference of the Parties to the United Nations Framework Convention on Climate Change (UNFCCC), held in Berlin. AIJ is intended to provide an impetus to investment and co-development of advanced technologies that reduce the rate of greenhouse gas emmissions while advancing national economic and development goals. AIJ or, simply, any well-thought out Joint Implementation scheme, may be a cost-effective way to achieve the objectives of the UN Framework Convention on Climate Change by encouraging technology transfer and co-operation between North and South. An AIJ Pilot Phase was included in the decision which forged the Berlin Mandate.

UNEP’s Executive Director, Elizabeth Dodeswell, in her address to the informal forum in San Jose, said that, ‘Joint Implementation, whether or not it involves credits but most particularly if it does, must be devised with one overriding consideration-it must be fair.’

Opponunities to reduce or mitigate greenhouse gas emissions are often more cost-effective in developing countries. As a result, joint implementation strategies might involve a developed country investing resources and technology in a developing country in exchange for emission credits. As Ms. Dodeswell pointed out, it may not however be enough for Joint Implementation agreements to be struck on a willing buyer, willing seller basis, but in addition, will require assessment and brokering through a neutral international process, bringing objectivity to the transaction and monitoring the implementation, to ensure fairness throughout.

At the Second Session of the Conference of the Parties to the United Nations Framework Convention on Climate Change held in Geneva, 8-9 June, 1996, the implementation of the Convention was reviewed. The Ministers and other Heads of delegations present stated, among many other things, that they will: ‘Instruct their represen-tatives to accelarate negotiation on the text of a legally-binding protocol or another legal instrument to be completed in due time for adoption at the third session of the Conference of the Parties. The outcome should fully encompass the remit of the Berlin Mandate…’ In addition, one of the particulars noted is ‘quantified legally-binding objectives for emission limitations and significant overall reductions within specified timeframes, such as 2005, 2010, 2020, with respect to their anthropogenic emissions by sources and removals by sinks of greenhouse gases not controlled by the Montreal Protocol.’ The goal of all these Climate Change meetings is spelled out in Article 2 of the Convention. Heavily summarized, it calls for, stabilization of atmospheric greenhouse gas concentrations in a timely manner in order to avoid climate change with dangerous consequences so that economic development may proceed in a sustainable way.

The Third Conference of the Parties, referred to in the preceding paragraph, will be held in Kyoto, Japan in 1997. Let us hope that agreement can be reached and carried out in a fair and constructive manner so that talking about the weather in this or future generations may continue to be a pleasant conversation- opener. Recognizing that, in today’s world, it is intolerable for 800 millions to be suffering from hunger and malnutrition and that it is everyone’s right to have adequate food to survive, the United Nations must reorganize itself in order to meet this challenge. The United Nations work in the field of peace and security is no less relevant: more effective conflict prevention and resolution efforts hold the promise of preventing the loss by millions of people of food security, particularly in the poor countries. At long last, very important principles on which to base our future action can be found in the results of previous world conferences and summits, including Rio, Vienna, Cairo, Beijing, Copenhagen and Istanbul. All conferences held so far have confirmed that environment matters all over the world. It matters as a set of interconnecting problems that threaten the quality of life and the sustainability of economic development worldwide. The environment is a global issue affecting people in developing and developed countries alike, and linking them in the need to take immediate action.

Today, there are 1.5 billion people living with dangerous air pollution, 1 billion without clean water, 2 billion without sanitation. Food production has doubled worldwide in the past quarter century- but at the price of loss of crop diversity, increased chemical contamination and loss of natural habitats. Around one-seventh of tropical forests have been lost in the past 25 years. These are not just local problems; their global impact takes the form of growing regional pollution, the spread of epidemic disease, the loss of biodiversity, global climate instability and the likelihood of mass migration from lands that can no longer support their populations.

Fortunately, the old notion of ‘development versus the environment’ has given way to a new view in which economic development and environmentally sustainable practice go hand in hand. Increasingly the idea of environmentally sustainable development is influencing the thinking of policy makers, international development agencies, and corporate executives. At the same time, years of environmentally conscious practice have produced advanced and cost-effective technologies and know- how. There are no longer either intellectual or technological impediments to the environmentally sustainable management of development.
