All of the world's rainforests will be gone in about 100 years because of deforestation. Deforestation is the clearing out of forests. If there weren't rainforests it would cause unknown effects on the world climate. It would also kill most animal and plant species.There are different types of deforestation. One type is called "Slash and burn" agriculture. This is when poor farmers chop down a small area in a rainforest and burn the tree trunks. Another type of deforestation is called commercial logging. Commercial logging is when you cut down trees for s ...view middle of the document...
In some countries farmers don't have money to buy necessities and depend on raising crops for food and to sell. Deforestation also occurs to construct towns, streets and dams that flood large areas. Deforestation for construction is only a very small part of the total deforestation.7 percent of the dry surface on earth is covered by rainforests. 5 to 8 million species of living things are found on the planet. Half of those species live in rainforests. It is estimated that up to 137 species disappear each day all over the world. This is because many plants and animals that require a special habitat live in small areas. This makes them really at risk to extinction when it comes to deforestation. If their habitat is destroyed, those certain species that live there are most likely to become extinct. Some organisms are losing species that they depend on which makes them face extinction as well.It is hard to determine the actual rate of deforestation. To study the rate, scientists analyze satellite imagery of forested areas that have been cleared. It is estimated that 53,000 square miles of tropical rainforests were destroyed each year in the 1980's. Scientists are currently studying the rate of deforestation for this decade, and how it changes from year to year.
