What is a Rainforest?

A rainforest is a wet environment. Animals that live in this environment need water to survive. There are two different types of rainforests.  There are tropical and temperate rainforests.The difference between the two rainforests is that a tropical rainforest is a warm environment and a temperate rainforest is a cool environment. Rainforests are the earth's oldest living ecosystems. A large number of animals and plants live there. Most rainforests are located around the middle of the earth, near the equator.
