deforestation effects

deforestation also leads to desertification because the trees and plants aren't there to hold the topsoil in place, and the soil blows away, leading the land to become desert.

animals that depend on the rain forest could die off and become extinct.half of the worlds species live in the rain forest, about 1/4 of the worlds species would die off.

deforestation is one of the worlds most worst land use problems, especially in Africa.
most of deforestation is caused by cattle ranchers, and small scale agricalture.
12 million hectares of forest are cleared annually.

if no steps are taken to protect the rain forests they could be gone by the year 2050
