HABITAT DESTRUCTION- orests all over the world are being cut down and burned for many reasons. Forests in the tropics are cleared to make room for farms, but tropical forest soil is very poor, and so farmers have to keep moving on and destroying more and more forests to grow their crops. Companies also cut down forests for their timber, or to make room for other plantations, in which most native animals and plants cannot survive.
