Rainforest regions are found in the tropical zone, in Africa, Asia and South America.

The Sun shines directly at the planet's equator troughout the year. This results in a warm, tropical climate. In addition, lowland areas near the equator receive plenty of rainfall. When the climate is both warm and humid, there is a lot of plant growth. Because of this, the African equatorial regions are dominated by thick, lush forests. These forests are called rainforests because of the high amount of rainfall they experience.

Rainforests are not very suitable for human habitation. Heavy rainfall results in floods, which damages roads. The warm, humid forests are full of stinging insects and other pathogens. This is why rainforests have been almost untouched by humans for thousand of years. Recently, however, people and large companies have begun to use the vast natural resources of the African rainforests at an alarming rate. Because of this, the rainforests are in danger of becoming destroyed.

Rainforests are the home of incredibly diverse animal and plant species. The rainforests must be protected in order to preserve this biodiversity.
