What is a rainforest?

A rainforest is a dense jungle ecosystem that can be found along the equator. As its name implies, the rainforest receives a large amount of precipitation.  It averages 160-300 inches of rain per year. In comparison, Los Angeles, CA only gets 10-20 inches of rain each year.

There are rainforests on several continents including South American, Africa, Asia, and Australia. Despite what sounds like a large amount of land, rainforests cover only six percent of the Earth’s surface. Yet, incredibly, they contain more than half of the world’s population of plants and animals. Rainforests are home to as many as thirty million different species of plants and animals. Many of these plants and animals species cannot be found anywhere else in the world.
