Rainforests are tropical forests that receive a large amount of rainfall each year. They are located in the tropics near the Equator where the climate is warm and stable. Rainforests are important because they stabilize the climate, provide habitat for many species of plants and animals, maintain the water cycle, protect against natural disasters, are a source of medicines and foods, support indigenous people, and are interesting places for visitors. Rainforests have exceptionally high biodiversity due to their favorable climate, supporting over half of the world's plant and animal species in only 2% of the Earth's land.
