The planet has lost about 40% of its original forests due to human activities such as logging, mining and petroleum exploration, agriculture, and urban sprawl. Each year, 120,000 square kilometers of forest is lost in the tropics alone, not to mention the cutting of swathes of temperate forest in Russia, Canada, and other countries.
One immediate and devastating effect of this deforestation is a loss of biodiversity. Forests are incredibly rich in plants and animals; tropical forests alone are home to more than half of the world's species, despite covering only 7% of the land surface on Earth. Most forest animals, and nearly all of the plants, are unable to survive outside of the forest ecosystem, so when the trees are cut down, they die. Two-thirds of the world's vascular plants live only in forests, along with 2,600 species of birds, and a staggering 30
million species of insects! Humans haven't yet discovered all of even the mammals that live in forest environments; just in 2007, scientists described for the first time an entirely new genus of forest monkeys from Tanzania, plus the world's largest rat in Indonesia, a giant elephant shrew in East Africa, and a number of other species. Every one of these new discoveries is critically endangered due to deforestation. This is cause for concern not only because these plants and animals may hold cures for some human diseases, but also because of the intrinsic value of each species. They have been striving and surviving for millions of years, developing exquisite adaptations to their forest homes, yet we as a species are mowing them down in the blink of an eye.
The second effect of deforestation, larger even than biodiversity losses, is global warming. Forests are carbon sinks; that is, the trees and other plants absorb carbon dioxide and incorporate it into their cells. When forests are cut down and left to rot, or even worse, burned, all of that trapped carbon dioxide escapes
