Tropical rain forests are very old , thick forests where it rains more than 1 . 8 meters per year . They are found in the Amazon region of south America , as well as Central America , Africa , and Asia . There are the upper level and lower level . Each level of the rain forest is its own world . Unfortunately , humans are still destroying the earth ' s tropical rain forests nearly 80 , 000 square kilometers a year . The population in cities all over the world is growing , and more and more wood is need to build huge new building and more and more food so it seems like a good idea to clear the rain foreat . Why shoud it matter to a businessperson , a farmer , or a student that people are destroying rain forests thousand of meters away ? ???? For anyone who takes medicine , wears running shoes , or use envelopes the destruction of the rain forest does matter . All these come from this and also world climate does . So the destruction of rain forests is an international problem . one country or even a few countries cannot solve the problem alone . The nations of the world must work together must work together to find a solution before it is too late . ..
