Rainforests are very dense, warm, wet forests. They are havens for millions of plants and animals.
Rainforests are extremely important in the ecology of the Earth. The plants of the rainforest generate much of the Earth's oxygen. These plants are also very important to people in other ways; many are used in new drugs that fight disease and illness.

Rainforests are forests characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1750–2000 mm (68-78 inches). The monsoon trough, alternately known as the intertropical convergence zone, plays a significant role in creating Earth's tropical rain forests.
From 40 to 75% of all species on Earth are indigenous to the rainforests.[1] It has been estimated that many millions of species of plants, insects, and microorganisms are still undiscovered. Tropical rainforests have been called the "jewels of the Earth", and the "world's largest pharmacy", because of the large number of natural medicines discovered there.[2] Rainforests are also responsible for 28% of the worlds oxygen turn over, often misunderstood as oxygen production,[3] processing it through photosynthesis from carbon dioxide and through breathing to carbon dioxide.
The undergrowth in a rainforest is restricted in many areas by the lack of sunlight at ground level. This makes it possible to walk through the forest. If the leaf canopy is destroyed or thinned, the ground beneath is soon colonized by a dense, tangled growth of vines, shrubs, and small trees called a jungle. There are two types of rainforest, tropical rainforest and temperate rainforest.

Arbor phytocoenosium thinking that equatorial rain forest is that the finger is cool , moistness is rainy , the high temperature , structure arrangement of ideas is not obvious , tier of outside plant is rich like equatorial rain forest (tropical rain forest). Equatorial rain forest scatters mainly in 5 ~ the equator south north latitude tropical climate area within 10 degree. Much annual here high temperature rain, has no the obvious season difference, annual mean temperature 25 ~ 30 ~C, the monthly the coldest mean temperature is in 36 ~C following also in 18 ~C the above , exceeding maximum temperatures majority. Annual amount of precipitation exceeds 2 000 mms generally , some go so far as to amount to 6 000 mms , annual rainfalls distribute homogeneous , throughout the year moist, air relative humidity above 90 %.
