Biodiversity impact
It was found from the surveys that most frequently suggested impacts that deforestation has on the environment are extinction of animals, loss of habitat, pollution and global warming.
Extinction of animals
There are about 7% of tropical forests around the world even though this might sound like a small number it contains about half of all the species on earth. Many of the species that live there have microbiological connection to the forest so they can become extinct even if there is a small disturbance. The animals that do survive after the forest has been cut down will die painfully. People may disagree about whether the extinction of other species through human action is an ethical issue, but there is little doubt about the practical problems that extinction poses.
Loss of habitat
The high temperatures and heavy rains in the tropical forests wash all the nutrients from the soil. The fertility that exists in tropical forests is not provided by the soil, all the nutrients of a tropical forest are from the plants and the decaying plant and animal matter on the forest floor. When a region is deforested for agricultural, the trees and plants are usually burned to make a nourishing layer of ash. After a few years the nutrients in the soil is lost which makes it impossible to grow crops. Once this happens this area is turned into a cow pasture. This will make the regrowth of the forest impossible.
Global warming
Pollution is a major problem all over the world. Pollution releases a lot of carbon into the atmosphere. The trees in rainforests make the biggest contribution in removing carbon dioxide from the atmosphere and replacing it with oxygen. If all the trees are cut down the amount of carbon in the atmosphere will increase eventually heating up the earth. This will cause an increase in temperature and will make it difficult to cool down as there are no trees around. Also this will lead to an increase in Global Warming which will destroy the other environments around the world. Examples are the melting ice caps and the bush fires.
