“Free radicals” are a special type of atom that have been linked to many age-related diseases. They form as a result of a process called Oxidative Stress, which takes place when an oxygen molecule splits into single atoms with unpaired electrons. The nature of electrons is such that they like to be in pairs and as a result will “freely” and “radically” search throughout the body for another electron to pair with. They could almost be considered romantic if they were not so dangerous!

Their main danger comes from the damage that they cause to cells or cell membrane, proteins, and DNA. Cellular damage occurs when free radicals travel through cells and disrupt the structures of other molecules. The gradual accumulation of them, and the increased damage that builds as more and more of them collect, is what helps cause many of the aforementioned aging diseases. Our body is under constant assault from oxidative stress, and cells may function poorly or die if it occurs too frequently and without proper bodily maintenance.

Free radicals are a waste byproduct that form as a result of various chemical reactions that take place during our bodies’ normal metabolic processes. They are then “dumped,” and their eventual buildup will often harm our bodies much like how factory waste harms the environment However, they are not entirely useless; it is impossible for our bodies to turn air and food into chemical energy without a chain reaction of free radicals. Free radicals are also a critical part of the immune system, as they additionally move through our veins and can confront foreign invaders [1].

What are free radicals?

Understanding free radicals necessitates an elementary knowledge of chemistry.

Electrons orbit around atoms in levels called shells. Each shell is filled by a fixed number of electrons, and when the first shell is full then electrons will start to fill the next shell.

If there is an atom whose outer shell is not full then it may bond with another atom by using the electrons to fill its outer shell. These types of atoms are known as free radicals.

Atoms that have a full outer shell become stable, however free radicals are unstable. They are “desperate” to acquire the full number of electrons that are necessary to fill all of their shells and will therefore react quickly with other substances.

Take the example of oxygen molecules. If they split into single atoms that have unpaired electrons then they too will become unstable free radicals that seek other atoms or molecules to bond to. If this procedure continually occurs, then it will begin a process called oxidative stress.

Smoking, UV rays, air pollution, fast food, pesticides, ionizing radiation, drugs, and inflammation have all been linked to the formation of free radicals. We must be diligent when it comes to understanding how these influences can affect our bodily health, and then fight back with natural antioxidants.

Free radicals are heavily linked to aging

One of the effects of oxidative stress is that it can damage our body’s cells and thus promote many of the diseases and symptoms related to aging, such as wrinkles and gray hair. They will take electrons from other atoms in order to become more stable, a process that may cause diseases or signs of aging [2].              

In 1956, the “Free Radical Theory of Aging” was outlined as a way to understand how exactly our bodies age over time. Everybody ages, and as we age our body loses its ability to fight the effects of free radicals. Over time our bodies produce more free radicals and more oxidative stress, which increases the rate at which cells are damaged and thus can bring about degenerative processes.

Many age-related diseases such as muscular degeneration, certain cancers, atherosclerosis, cardiovascular disease, emphysema, Alzheimer’s disease, Parkinson’s disease, ulcers and all inflammatory diseases such as arthritis and lupus, and many others are linked to free radicals. Free radicals can be found in the food we eat such as fried foods, the medicines we take, the air we breathe, and the water we drink. Free radicals are also found in alcohol, tobacco smoke, pesticides, and air pollutants.

Several studies and theories have been linked to oxidative stress and the buildup of free radicals including: [3]

• Genetic degenerative diseases, such as Huntington’s disease or Parkinson’s
• Age-related changes in appearance, such as loss of skin elasticity, wrinkles, graying hair, hair loss, and changes in hair texture
• Cataracts and age-related vision decline
• Diabetes
• Cancer, which is associated with chromosomal effects and oncogene activation due to the reaction of free radicals [2]
• Central nervous system diseases, such as Alzheimer’s and various forms of dementia
• Cardiovascular diseases due to clogged arteries
• Autoimmune and inflammatory disorders, such as rheumatoid arthritis and cancer

The free radical theory of aging is comparatively new; however, several studies boost its credibility. Researchers focused on cell’s mitochondria, the “powerhouse” that process nutrients to power the entire cell. Experiments on rats, for example, showed a noteworthy increase in free radicals as the rats aged. These alterations coincided with age-related declines in their health. These experiments also showed that free radicals produced in the mitochondria harm the substances that the cells need in order to work properly. This damage causes mutations that produce more free radicals, thus accelerating the process of damage to the cell. This helps explain aging since aging quickens over time. The gradual, but increasingly rapid buildup of free radicals, offers one explanation for why even healthy bodies age and depreciate over time [2].

Antioxidants can stave off free radicals

Antioxidants, molecules that prevent other molecules from oxidizing and thus undergoing oxidative stress, can help to avert the harmful effects of free radicals. They can also decrease or even nullify the effects of free radicals, as they can provide an electron to free radicals and thereby reduce their reactivity. The uniqueness of antioxidants is that they can donate an electron without becoming reactive free radicals themselves.

There is no single antioxidant that can combat the effects of every free radical. Free radicals have different effects in different areas of the body, and every antioxidant performs differently due to its chemical properties. Antioxidants such as vitamins C and E, beta-carotene, glutathione, and plant estrogens called phytoestrogens all scavenge the body and help remove free radicals. Honey can also function similar to antioxidants by removing free radicals. Additionally, selenium, a trace metal that is required for proper function of one of the body’s antioxidant enzyme systems, is sometimes included in this category. The body cannot manufacture these micronutrients so they must be supplied in the diet.

Foods that are rich in antioxidants include citrus fruits such as oranges and limes, berries, and many other fruits that are rich in vitamin C. Carrots are known for their high beta-carotene content, while the soy in soybeans, and some meat substitutes, are high in phytoestrogens. Apricots, spinach, mangoes, pumpkins, broccoli, and eggplants are all also helpful, along with a plethora of other fruits and vegetables [4].

More research needed

A 2010 study on antioxidant supplementation for the prevention of prostate cancer found no benefits. Furthermore, a 2012 study found that antioxidants did not lower the risk of lung cancer. On the other hand, the study found that people who were already at a heightened risk of cancer, such as smokers, actually had a slightly elevated risk of cancer due to antioxidants.

Some investigators have found that supplementation with antioxidants is injurious when people take more than the recommended daily allowance (RDA). A recent analysis found that high doses of beta-carotene, or vitamin E, appreciably increased the risk of dying. One study found that long-term use of beta-carotene could reasonably reduce the risk of age-related mental problems [4]. But perhaps one of the most important discoveries is that antioxidants are unable to “cure” the effects of free radicals completely [5].  

Additionally, we do not yet fully understand why free radicals form in the first place. They may result as an early sign of cells fighting diseases, or that free radical formation is simply a natural expectation that comes with aging. It is not possible to understand them completely without more conclusive research, which should be encouraged considering the significant impacts that free radicals can have upon our bodies.

Beginning in July of 2019, the Brazilian Amazon rainforest has been up in flames, burning up the lush foliage and engulfing much of the wildlife, along with many Indigenous groups, in its fiery wake. Yet, it’s receiving little to no media coverage due to the global community’s seemingly unconcerned liability to take action. Greenpeace, the international environmental organization, is holding Brazil’s current government under President Jair Bolsonaro responsible as the primary cause of the fires due to negligence. They claim that mass deforestation has been taking place at an increasingly alarming rate, especially following Bolsonaro’s election, and farming and ranching that have also been taking place in surrounding areas have been contributing to the rise in destruction as well (Greenpeace 2019) [1]. These problems have not been addressed in a timely manner.

Various ideologies, such as Dualism, have been heavily promoted within the past few centuries have also shifted humanity’s conscious to one that is less ecologically friendly and more materially greedy. Without help from the international community and the government of Brazil, the Amazon will continue to be subjected to destruction [1].

The Amazon is a massive area, covering roughly 2,300,000 square miles of South American land. It is one of the most important and critical components of the Earth’s delicate ecological balance and to date 2,240,000 acres have been burned due to the 2019 wildfires (in addition to the great amount of damage that has already been done). It is responsible for atmospheric oxygen composition and cleanliness, maintaining the atmosphere’s water cycle, and for the preservation of many rare animal and plant species. Much of the vegetation in the Amazon also includes important medicinal plant species that can be used to cure a multitude of illnesses and diseases [7].

Deforestation, which has plagued the Brazilian Amazon for decades now, is utilized for the establishment of farms and ranches, which has tripled the number of cattle present in this area and surrounding regions (Dwyer 2019) [2]. Farming and ranching have caused more pollution and the poisoning of, not only the lands in these areas, but the entire well-being of our Earth and atmosphere as a whole. Production of methane from cattle and other pollutants are consequential of farming and ranching, and contribute greatly to fire susceptibility of the Amazon. The fires have spiked in these areas where deforestation and pollution are at their peaks (Dwyer 2019) [2]. When it comes down to it, the Brazilian government, in general, expresses lesser concern, even though they make it apparent that they “may look into measures to combat these fires” (Greenpeace 2019) [1], it seems politics is snaking its way into crisis affairs and impeding them once again instead of acting upon them with optimism. [2]

In the past, Brazil was much more involved in helping to prevent deforestation in both public and private lands of the forests. In 2006, the government passed the Public Forest Management law. This law established concessions and funding for forest conservation and regulations involving deforestation in public areas of the forest. Other organizations and institutions that were established following this law being passed included CONAFLOR (a civil society forestry board), IMAZON (an NGO that monitors deforestation), FUNBIO (an environmental fund that budgets financing towards protected lands and biodiversity), INPE (a Brazilian space observation company that also monitors deforestation), and lastly IPAM, a governmental research institution that focuses on deforestation, climate change, and natural resources in respect to the Brazilian environment (Yale 2019) [10]. Indigenous individuals and tribes within the Amazon, along with private property owners, have also gone to great lengths to prevent deforestation and have made the most difference and impact in doing so (Yale 2019) [10]. It was ultimately a grassroots movement of people standing shoulder-to-shoulder, and not a specific government agency, that was able to make the most progress to preserve much of the Amazon’s beauty and help stave off deforestation [5].

Despite the efforts that have been exerted into the establishment of laws, policies, and government organizations in order to protect the Amazon, protection of the Amazon has been much neglected for now and for future generations. Other countries, such as the United States and the United Kingdom, also believe that Brazil is not doing enough. But, President Bolsonaro seems to have many political reasons to continue to resist international help to halt the fires and stop deforestation. His outspokenness of his pro-deforestation views has ignited a wave of eager ranchers and farmers to continue, and even escalate, their destruction of the Amazon (Specht, 2019) [9].

Religion and environment

As for religious and spiritual views of the environment, some people have manipulated various religious teachings to promote negative ideologies and views of the environment rather than positive ones. These ideologies argue that all animal and natural life was created to serve mankind, and that humanity has no responsibility to take care of our planet or maintain a balance of life in the natural world. The Indigenous people of the Amazon, such as the Xingu tribe, view these perspectives as “predatory” and are in fear that everything they know and love will be taken away from them due to the utter destruction, negligence and lack of aide provided by the government. Many leaders of these tribes call these events the “destruction of Mother Earth” and the fires that have been set ablaze are Mother Nature’s calls for help (Johnson 2019) [5]. To provide more of a visual, there are roughly 817,000 individuals in Brazil who self-report themselves as indigenous, and there are 67 known tribes within Brazil that do not have contact with the outside world as of now. The Amazon serves as these tribes’ livelihood. Many individuals who are a part of these tribes were born in the rainforest, grew up in the rainforest, hunt in these forests, and make their living in these forests; Amazon is all they know and love [5].

In an article titled “Dualisms – Environmental Humanities”, Dualism is outlined as one entity being viewed as “genuine and superior” while all other life is categorized as “other”. This concept has had major impacts on the way we as humans view the products of our environment. Dualism fuels the idea that the environment, and all non-human living beings within it, are put on this Earth specifically to serve us as humans and us alone. This ideology allows people to infer that there is a distinct separation between humans and every other living being on the planet, and that these distinctions make it possible for humans to justify destructive actions towards the environment. In addition to these ideas, the concept of “ecological consciousness” is found to play an important role in the relationship between religion and in being mindful of our consumption of our environmental resources, as we continue to consume them faster than they can regenerate themselves (Andrew 2019) [3].

Christianity and Islam are two religions that promote ecological consciousness and believe that the Earth’s resources should be treasured and treated with respect. This places a strong emphasis on environmental protection and environmental rights, which thus encourages followers and believers of the religion to do the same. Religion provides us with morals and values that can be adopted when it comes to our views of all other living things whom also share this Earth with us; not only our views of these beings, but how we treat these beings as well. Finally, Christianity and Islam argue that “being a servant of God” also encompasses the idea that Man must protect what God has entrusted him with, the environment included (Pahl 2018). Specifically in regards to Islamic views, Tawhid, meaning the “oneness of God”, is a critical component that Islam bases itself upon. The religion of Islam, like Christianity and Judaism, is a monotheistic religion, meaning that these religions base their values and morals on the belief that there is only one God. All existence, including the human beings, are His creation, and in that sense they are part of the one same whole and exist interdependently [4][9].

Despite the disregard of public outcries, there are ways that everyday individuals, such as ourselves, may combat this issue head on and on our own without aide from government agencies. Our first mission should be to make this issue as public as possible. Share as much reliable news coverage as you possibly can and spread the word as far as it will go. If you are able, donate to wildlife conservation and forestation projects held locally or online. Spread knowledge and education. Call attention to higher powers. Other ways in which the everyday community can make a difference include supporting Indigenous groups and tribes residing in the Amazon; begin developing an allyship by using less paper and wood products, by consuming more ethically sourced foods, by voting, and by challenging large corporations who are impeding on the health improvement of the Amazon [8].

Let’s take action! The Amazon, its people, and its wildlife need the world’s cooperation, or they do not stand a chance against the ravenous gluttony that is deforestation. We can save the lungs of our Earth together.

We eat, sleep, and go to the bathroom. Yet, we never think about how all these physical needs are processed in the systems of our body when they are functioning normally.

Yes, our bodies are created with perfect systems by which our all kinds of needs are met. The digestive system is one of them. Our intestines are key elements of this system, so much so that asking someone “How are your intestines?” would be as comprehensive as asking “How are you?”

Digestive system

Food is critical to life. A human being can bear hunger for one month at most and can only endure a few days of drought. Thus, eating and drinking is crucial.

Foods as we eat them are not convenient for use by the cells. Food must be broken down into smaller pieces. This process begins in the mouth and ends at the anus, and it is called digestion.

The main task of our stomach and intestines is digestion. The teeth, salivary glands, the tongue, and the gullet – as well as swallowing – are essential secondary elements. Additionally, if the pancreas or liver fall ill, it can paralyze the whole system. While also working with the circulatory system, kidneys have the task of reabsorbing useful substances like glucose, amino acids, and water.

Our digestive system works together with the urinary system and the digestive organs like a factory. How these parts work together is still not fully understood, but more detailed research has been performed and revealed more secrets of the digestive system. By means of every discovery, it is realized that this perfect creation has a more intricate structure than is known.

The brain in the intestine

There are more neurons in our intestines than in our spinal cord and the intestines are created in a way that can move independently from the central nervous system. They have their own nervous system, known as enteric nervous system (ENS), which is also called the “second brain. “Within those yards of tubing lies a complex web of microcircuitry driven by more neurotransmitters and neuromodulators than can be found anywhere else in the peripheral nervous system. These allow the ENS to perform many of its tasks in the absence of central nervous system (CNS) control…” [1]. Thus, “… isolated segments of intestine can independently coordinate propulsive movements and propel content without any neural connections to the brain or spinal cord [2].

The intestines take action when food comes into the stomach. This movement is known as colonic migrating motor complexes (CMMC), and it moves the substances that cannot be digested, like bone and fiber. According to neurophysiologist Nick Spencer et al, “The gut wall contains a complete network of intrinsic nerves capable of propelling contents along the bowel, without any requirement of nerves originating in the brain or spinal cord” [3].

Eat different types of food

70% of our immune system cells are in our intestines. A big part of the approximately 38 trillion bacteria in our body are in our intestines, and they are useful; they have a big role in digesting food. Different groups of bacteria feed on different types of food; so for intestinal flora it is very important to have a variety of food on our table. For the ideal day on a plate Dr. Megan Rossi recommends people should “aim for at least 30 different plant species per week.” “The reason for this is that each plant contains different types of fibres and phytochemicals (the super healthy components of plants) that feed different good bacteria. The more plant variety, the more variety of gut bacteria – which is associated with health and happiness” [4].

Pets in our body

For Dr. Megan Rossi, “microbes are like our pets, so you have to take care of them and feed them” [5].

Of course, germ flora in our body is not just limited to the ones in the intestines. Bacteria, viruses, and fungi in our body are nearly scattered throughout the whole body. These living things produce pellicle on our head skin, irritate the gaps between our toes, live on our skin, are on duty among our teeth, and have ecosystems and assigned positions convenient to them. According to the situation, they keep their living spaces healthy or unhealthy. Although they number 50 trillion, they are approximately 200 grams of our body weight.  

Useful microbes

An average size human adult houses about 10¹² bacteria on the skin, 10¹⁰ in the mouth, and 10¹⁴ in the gastrointestinal tract [6].

These microorganisms are useful microbes with duties in our body. The harmless flora of microbes is generally present on the skin, mouth, teeth, nose, throat, and bowel and genital areas. There isn’t normal flora in internal organs except the large bowel. Internal organs have no microbes. If we look closely, flora is inserted in every part of our body which is dirty and has contact with the outer environment. If it was not for the useful flora, microorganisms causing illness would settle instead. Only intestinal bacteria are permanent microbes which are useful. For example, vitamin K plays a part in a crucial event like blood clotting and is produced in the intestine.

Control your stress

Research has revealed that mental and psychological stress affects the health of the intestines. Serotonin is produced automatically in case of need, and 85% of it is produced in the digestive tract. Stress suppresses the level of serotonin produced. Psychological illnesses are associated with low levels of serotonin.

Studies have shown that relaxing practices like meditation for 15-20 minutes can be good for health and reduce stress. At this point, daily prayers are a kind of therapy. Other ways to stay healthy include: avoiding things like alcohol and caffeine, and sleeping well.

Our body has ways of telling us when it’s not healthy. For instance, we can learn the digestive tract isn’t healthy if we have to use the toilet more than three times a day and fewer than three times a week.

Despite advances in technology, computers still can’t come close to the power of the world’s most remarkable computer – the human brain.

Computing machines have seen three phases: the tabulating phase, the programmable phase, and now the new era of computing, the cognitive phase [1]. Tabulating machines performed a fixed task, whereas programmable machines could be reprogrammed to execute different tasks without any change in the hardware. Cognitive machines, however, promise learning and reasoning capabilities.

The possibility of such machines raises the question: is cognition the ultimate test for conscious existence? What do we know about cognition? How do we define intelligence? The questions go on and on. One thing, however, everyone seems to agree with is the fact that understanding the mechanism of human cognition is the key to developing advanced artificial intelligence, and cognitive machines.

Cognitive machines have the ability to learn, and they employ artificial intelligence to “reason.” Artificial intelligence is defined as, “The science of making machines do things that would require intelligence if done by men” [2]. The good news is that cognitive computing is no longer an esoteric pursuit of some futurists. It is, and has been, essential for the operation of many big-data driven processes. The 21st century has been flooded with data coming from almost every aspect of our lives. Technology has made it possible to generate data at an exponential rate. Temperature distribution throughout our buildings, the number of people diagnosed with cancer in the last six months, real-time changes in customer preferences, ethnic profiles of college applicants, and the top three words trending in online conversations at this very moment, are some examples of the kind of data available today.

As the amount of data generated increases, it also becomes harder and harder to process and make sense of the data collected. Our “greedy and ambitious” human nature does not want to waste, and it wants to use every bit of available data. This is where it becomes imperative to have a computing machine that goes beyond performing pre-programmed tasks and learns as it goes, without human interference. For this kind of computing, we need cognition.

The biggest challenge in imitating human cognition is to understand how cognition happens in the brain. It is obviously beyond our ability to monitor such activity that is constantly taking place in our brains, let alone recreating such marvels in the first place. Nevertheless, it will be a great achievement if we can manage to somewhat imitate human cognition, even partially. It would open a whole new era in terms of what can be achieved from a computing standpoint. For instance, the entire curriculum of a college degree can be processed by a cognitive machine in a fraction of a second; such machine can digest the whole of medical literature in a short period of time, provide human doctors with second opinions on their diagnoses [3].

Despite the fact that there have been substantial improvements in designing “intelligent” computing machines, mimicking the hardware of the human brain and simulating its decision-making processes, have posed three fundamental challenges: a hardware with comparable processing power and memory, a software algorithm to implement intelligent behavior, and the necessity of both being self-adapting and self-improving.

First of all, human intelligence has not been fully characterized – its capabilities and limitations are still unknown. This lack of knowledge makes it difficult, and perhaps even impossible, to reduce such intelligence to smaller, or simpler, modules. Therefore, we don’t have a good handle on how to mimic the human brain in a behavioral sense.

The second major problem is that we are still far away from having the hardware on which our “intelligence” software could run. Implementing intelligence in conventional computing machines, evidently, seems to be a futile undertaking. Programmable machines are no match for human brains; even the fastest supercomputers, taking advantage of thousands of processors, is able to mimic just one percent of one second worth of human brain activity-and even that takes 40 minutes [4]. Therefore, cognitive computing machines must incorporate different hardware architecture from conventional computers to achieve cognition comparable to humans. IBM’s SyNAPSE chip is one example of hardware inspired by the brain, and it has the potential to carry out the required, intense computations.

Lastly, the human brain and its cognitive power are constantly changing. Depending on various factors and experiences, our brains can improve or deteriorate; this is also true of our cognitive power. However, such improvement or deterioration could be in the form of a change in the physical structure or the amount of capacity utilized [5]. Such dynamic flexibility, also called Brain Plasticity [6], is essential to our intelligence. At this time, no self-evolving computing hardware has been worked out. However, promising developments have been reported with respect to cognitive computing machines that can learn – that is, they can make deductions and reach conclusions that are not preprogrammed.

Along the way, human supervision will be the ultimate guide in perfecting such imitation. Therefore, human cognition, taken for granted in our daily lives, remains to be the final frontier for our thousands-years long technological journey. Once again, the creation set the boundaries for human development.

The point of this article is not who hates who. Rather, we want to learn why people become angry with others who have different skin colors,

religions, or thoughts. This nightmare, known as racism, has been the source of great and frequent violence throughout history.

Who Was the First Racist?

The first racist was Satan, for he hated Adam. According to Qur’an 17:61: All angels prostrated [before Adam], except Iblis [Satan]. He asked: Shall I prostrate to one whom You made from clay? What was Satan’s biggest mistake? Instead of accepting the reality of diversity in creation, he sought to justify his rejection of Adam. He assumed and asserted that he was nobler than Adam. He did not ponder who decides everyone’s color, nation, and social environment, but justified his racist superiority: [God] asked: Why did you not prostrate when I commanded you? [Satan] replied: I am nobler than him. You created me from fire, but You created him from clay (7:12).

Since this early racist dialectic, all racist groups and their followers have used similar arguments to justify their beliefs and prove that they are the best. The result of such an effort has been a very bloody history.

We are living in a period of rapid change. Due to the global media, these changes affect everyone. Hate organizations use the media to expand their reach in totally new ways. Of course, this is not new: In Italy, in 1922, Benito Mussolini understood the power of the brand-new medium, radio, and he began to use it as soon as it was electronically possible in his country. Some years later he was quoted as saying, ˜If it weren’t for radio, I wouldn’t have the power over the Italian people that I have.(2)

In recent years, the Internet has become a major tool for extremist propaganda. Time columnist John Cloud makes a significant point:

He is absolutely right, for creating hate-filled Web sites is easier and cheaper than taking risks, such as public demonstrations and protests. Don Black, founder of a famous racist Web site, learned in jail how to use the Internet to spread his message. He started a Web site, which at last count had been visited by over 3 million people. It even has sections for women and children.

How Do Such Sites Affect People?

A recent race crime horrified the nation. On June 7, 1998, William King and his friends kidnapped James Byrd, an African-American, tied him to their truck, and dragged him to his death. How can a person become a racist murder? While covering the story, the American media found several reasons, among them that a hate group had agitated King while he was in jail. The Christian Science Monitor interviewed Clara Byrd-Taylor, Byrd’s sister, to get insight into King’s personality: After the dragging death of Texan James Byrd, his sister decided that he would not die in vain. She set out to discover what could have nurtured the hate that killed her brother. She found it on the Internet. ˜Prior to the death of my brother,’ Clara Byrd-Taylor says, ˜I had very little knowledge about the hate sites and what was happening with the hate groups around the world. I had heard isolated incidents, but I had not put all those things together.'(4) There are now over 600 hate Web sites, most of them targeted specifically at young people. The Internet and rock music are two key attractions for youth. CD and Web sites have presented young people with music mixed with advocacy of violence and racial separation Resistance Records, in Detroit, identified as a neo-Nazi music label, sells about 50,000 albums a year through its Web site.(5) Why are youths chosen as targets? Nowadays, more people feel lonely even though they live and interact with people all the time, such as in the workplace. But sharing social and moral values with some communities, like family, has been forgotten. People are losing themselves and, as a result, seeking a new identity that might solve their individual and social crises. Many young people feel isolated by the social structure, and so face an identity crisis. They feel alone, insecure, and abandoned. Music about violence offers messages that highlight the importance of rebelling against social discipline and authority. Being a part of the group and against others is a way to obtain a new social identity for many young people, who see everything in black and white. This is a very complicated problem without a clear solution. Many academic researchers and human rights groups are trying to learn how to overcome hate propaganda on the media. For instance, the Southern Poverty Law Center declared 10 ways to fight racism. They are as follows(6):

Act. Apathy is interpreted as acceptance.

Unite. Join those who oppose hate and work to eliminate it.

Support the Victims. Let victims know that you care, and report any hate directed toward you or people you know.

Do Your Homework. Learn how to identify hate groups and spread this knowledge to others.

Create an Alternative. Find another outlet for anger and frustration, and capitalize on people’s desire to do something

Speak Up. Expose and denounce hate wherever and whenever you can.

Lobby Leaders. Persuade political, business, and community leaders to take a stand against hate in the interest of their reputations and businesses.

Look Long Range.Create a bias response team and celebrate your community’s diversity and harmony.

Teach Tolerance. Bias is learned early, usually at home. Sponsor an I have a dream contest. Target youths who may be tempted by skinheads or other hate groups.

Dig Deeper. Study divisive issues so that you can determine your own prejudices, and then work to eliminate social prejudice.

Defining Censorship

One of the most contentious media-related issues is defining censorship. Governments are responsible for protecting their citizens from racist groups and propaganda. For instance, Canada and Germany are trying to catch people who use the media, including personal Web sites, to spread hate. But there is still one vital question that must be answered: Who defines protecting the people, especially the young, and protecting the freedom of speech? Prohibiting such speech is not the answer, because governments have abused this authority throughout history. Besides, modern technology and its products almost have eliminated the importance of physical borders as tools for governmental control.

What You Can Do

If you are involved in education or business, work to get your employers to focus on cultural diversity as a valuable human resource. Schools are many children’s first direct exposure to different cultures and peoples. The business sector often brings people who otherwise would not meet each other into close contact, thereby dispelling stereotypes. If handled correctly, deep biases can be destroyed in both children and adults. In addition, the importance of peace must be taught and reinforced in the home, school, workplace, and everywhere else. Create your own anti-hate Web site. Spread the information provided by such anti-hate organization Web sites as:

Subscribe to their publications, donate money or time, and participate in their activities whenever possible. Protest all radio programs and music that encourage this nightmare of modern times. Explain to your children why you oppose their listening to such programs or music. Sponsors and producers are not immune to public outcry and negative publicity. Remind the mainstream media that it has the vital responsibility of showing its audience how to live together without hate. If religious or racial discrimination are tolerated or even encouraged, the media only reinforces negative or distorted images and racism. Establish or join coalitions devoted to fighting hate messages. Explain to others that you do so in order to create a better future for everyone by trying to prevent the racist nightmare from destroying our good dreams for the future.
