South America - Amazon Rainforest Deforestation (Global ability to absorb adequate amounts of carbon dioxide are also Rainforest Deforestation) reduced. The increased levels of carbon dioxide contribute to what is called “The Greenhouse Effect.” The Greenhouse Effect The destruction of the Amazon rainforests is a serious concern. occurs when  elevated levels of carbon dioxide help to trap the sun’s energy in the Earth’s atmosphere. Just as a glass  According to the World Wildlife Fund,  more than 20% of the greenhouse traps the heat from the sun, the Earth’s atmosphere, when too much carbon dioxide is present, will trap the heat from rainforest has already been destroyed. This number grows daily the sun as well. As we continue to burn more and more fossil fuels, more and more carbon dioxide is put into the atmosphere. as the land continues to be cleared for agriculture, livestock Without healthy rainforests worldwide, the Earth cannot re-absorb enough carbon dioxide to lessen the impact and reduce the ranches, mining operations and logging. In addition, some forest greenhouse effect. areas are being purposefully burnt in order to make charcoal to Another issue caused by the destruction of the rainforests involve what is found in those forests. Many fruits, spices and other use as a source of fuel for local power plants.

Learn more about the Brazilian rainforests here. The Amazon Rainforest is known as “The Lungs of the Earth.” The amount of oxygen produced by the vegetation of the rainforest, as well as the amount of carbon dioxide that is absorbed by it, cannot be replaced. The destruction of the rainforest is believed by many to be a contributing factor to the global warming trend. As the forests are reduced the Earth’s
