The map below shows approximately where these forests are located. Each type of forest boasts a huge variety of wildlife. But sadly, our ever-increasing demand for wood and other resources means the forests and wildlife that lives there are increasingly under threat. Between 1980 and 1995 the extent of the world's forest decreased by an area about the size of Mexico.
Rainforest are a vital part of the world's complex and sensitive ecosystems.
Globally, they play an important role in regulating our climate. Locally, they act like giant sponges, soaking up rain and slowly releasing the water to the ground. The trees help hold the soil, which would otherwise be washed away to clog up reservoirs, rivers and irrigation systems. Many people rely on this water cycle to help grow crops and for drinking water. More species of plants and creatures live in the rainforests than anywhere else on Earth.
