  * Also, no one knows how destroying the rain forests will change the earth. We know that less rain will fall once the trees are gone. That may cause some rivers, which supply water to cities around the rain forest, to dry up during part of the year. Also, burning trees puts carbon into the air. Carbon absorbs heat from the sun. Experts are arguing about it, but it might be happening.
