... ple who have been using them for years in the rainforest. Another major problem is that shamans, or medicine men, who have hundreds of ingredients to plant properties are very elder and if that person dies without passing his knowledge to younger generations everything he knows is lost. As if the extinction of plants and animals were not enough, deforestation has been the cause of many indigenous tribes living in the rainforest to be wiped out. From over 6 million indigenous people inhabiting the rainforest of Brazil in 1500, only 250, 000 still exist today ().

Mining, ranchers, corporations among others have quickly been killing off tribes in a gruel fight for territory and interest. There are dozens of different tribes living in Brazil. Each with different customs and traditions but they all share certain characteristics. They are all dependent upon the Brazilian rainforest to survive. They kill wild game for food, live in small areas in the forest planting crops for food and live very secluded from civilization and the rest of the world. Indigenous tribes have taught us that earth and man can live in peace.

Not only are they threatened by outsiders interested in the land but by their younger generations who move out to the city and thus, lose the valuable information that the elders want to pass on, especially medicinal values of plants found in the rainforest. Indigenous people usually lose their land when they are moved because ranchers, miners, or logging companies decide they would like to purchase the territory. The intruders usually begin slashing and burning the territory they want and expect any tribe nearby to move to a different location. Many times the military is called in and the tribes are forced out of their land. Their human rights are usually ignored by the government and invasion of territory usually end up in bloody conflicts with the intruders. These people depend on the rainforest to survive.

The problem, as can be seen, is not only dangerous on a national level but worldwide. Another of these major ecological problems whose main cause is deforestation is global warming. Let us examine how global warning occurs: the sun releases heat which is absorbed into earths atmosphere. Earth then returns some of that heat in the form of radiation waves, part of the heat is absorbed by gases in the earth such as carbon dioxide and methane.

This process keeps the earth warm. Trees absorb the carbon dioxide and through the process of photosynthesis convert it to oxygen. As we keep reducing the size of our rainforests, which are responsible for 20 % of the oxygen produced in earth and as we keep releasing more and more greenhouse gases, which are carbon dioxide, methane, chlorofluorocarbons, and nitrous oxide into out atmosphere each year, the ecosystem is thrown off balance. These gases make earths climate warmer each year and so produce global warming (Global Warming).

Global warming could bring catastrophic results to the planet in general. Sea levels would rise, causing an ecosystem unbalance plus the relocation of people living near the coasts. Countless animals and plants that would become extinct because of climate change. Species would have to migrate elsewhere causing unbalance in their lives.

Agriculture would be affected tremendously since climate would change throughout the world, causing serious droughts and floods that would cost billions of dollars a year in lost revenue. Above the earth is a thin layer that helps keep atmospheric gases inside earth and acts as a shield from harmful rays emitted by the sun. The greenhouses gases mentioned above are deteriorating this protective layer, they are burning holes in it which permit the suns rays to enter our atmosphere easily. The sun rays that are entering the atmosphere are so strong that they act as radiation hitting us everyday. Skin cancer is becoming more and more common in recent years because of the ultraviolet rays that enter through the depleted ozone layer.

People suffering from respiratory illnesses such as asthma are also on the rise, because of the high levels of pollution we are suffering from large cities. Why keep destroying? you might ask, after reading all the negative effects deforestation might produce. The answer can be given in one word: money. Brazil is a country that is in a stage of development and deforestation is the main source of revenue. Logging is extremely profitable for companies.

The wood is used to make furniture, materials, and other wood products. Charcoal comes from the rainforest as well as paper. The United States, Great Britain, Belgium, and Japan are the biggest customers (Solutions). Another sad thing about this is that these companies pay extremely low prices per acre and making billions in profits.

The government is selling their property for prices incredibly low prices compared to the amount other countries are making off them. On the other hand, if Brazil was not selling the rainforest then it would have very little, if any, source of revenue. Many economists say that the destruction of the rainforest is inevitable and only natural. Brazil needs more room for its people since the population keeps increasing each year according to them. Economists also argue that if Brazil was not selling its rainforest then the country would be sunk in extreme poverty, crime, and they argue that we would still be losing it. According to Bjorn Lomborg, author of The Skeptical Environmentalist, everything we are fed by the media about the problem of deforestation is a lie.

Bjorn states that pessimist news sells so therefore the media exaggerates the truth greatly. According to him the rainforests are not disappearing as fast as we think and the problem is not ominous. 80 percent of the original forest cover is still in place then just about 20 percent of all tropical forests have disappeared (Lomborg 114). On the issue of global warming Bjorn presents interesting information. According to the author plants produce oxygen by means of photosynthesis, but when they die and decompose, precisely the same amount of oxygen is consumed (115).

Trees neither produce or consume oxygen according to his hypothesis since it is an equal distribution of give and take. He criticizes disinformation presented by other sources because according to him they have no grounds or bases for their allegations. In his book, he reminds us of when President Carter warned us that we would have very little, if any, rainforest by the year 2000 in his Global 2000 environmental report (113). Rapid destruction or slow destruction of our planets rainforests the problem is there.

There are many things we all can do in order to protect our forests from further deforestation. According to experts the rainforest will yield more profits if it is used for its fruits, nuts, oil and medicinal plants than if it is destroyed now for short term gains. The labeling of timber to be sold would be a giant help against deforestation. Labels indicating sound wood would be sold and customers with a more open and aware conscious would purchase timber that is not endangering any ecosystem.

Another huge solution to the problem is paper. If we consumed less paper thousands of acres of rainforest timber would be spared. Through another perspective, Brazils government needs to help fight its overpopulation problem since that is a giant factor with deforestation (Solutions). The government needs to educate its people and make them aware of the present problem and the magnitude its consequences can bring. Without an educated, aware society no plan or agreement will work. The fact that Brazils rainforest is disappearing is undeniable.

Whether it is going in slow or fast pace does not matter very much. We, as a society need to help protect the rainforests not only because of their beauty but because of the importance in this planets balance with nature. As stated before, the problem does not affect Brazil only, it is a delicate issue whose consequences affect every living thing on this planet. Unless we take action today tomorrow might be too late.
