Tropical rainforests cover about 6% of the Earth's total land surface. They are mainly located around the belt at the equator. The climate of the rainforest is warm most of the year and has a lot of rain through most of the year. The climate is perfect for animals and plant growth. Even though the rainforests cover such a little amount of land mass of the Earth, they are home to the largest number of plant and animal species in such a concentrated area. Scientists believe that the tropical rainforests of the world might hold up to ninety percent of the plant and animal species on earth.

The Amazon drains the world's largest tropical rainforest, and is thought to have about 3000 species of fish, more than are contained in the entire North Atlantic. It is estimated that a typical patch of rainforest just six kilometers square contains as many as 1500 species of flowering plants, 750 species of tree, 400 species of bird, 150 species of butterfly, 100 species of reptile, and 60 species of amphibian. There are so many insects that they can only be guessed at, but one-hectacre (2.5 acres) may contain as many as 42,000 species.
