Tropical rainforests are forests characterized by high rainfall, with definitions setting minimum normal annual rainfall between 1750 mm and 2000 mm.Very hot and humid. In contradiction to popular belief, rainforests are not major consumers of carbon dioxide and like all mature forests are approximately carbon neutral.^[1]^[2] Recent evidence suggests that the majority of rainforests are in fact net carbon emitters.^[3] However, rainforests do play a of rainforest leads to increased levels of atmospheric carbon dioxide. Rainforests may also play a role in cooling air that passes through them. As such, rainforests are of vital importance within the global climate system.

Because there are multiple branch levels and microclimates in a rainforest, it is a hotspot for biodiversity. Many species of plants and animals still have yet to be discovered. The rainforest also provides a multitude of resources for local, indigenous people including food and shelter. A number of plants found in the rainforest can also be used for medicinal purposes.

[edit] Problems in tropical rainforests

Deforestation of the world’s rainforests releases carbon dioxide into the atmosphere. The Amazon rainforest has been referred to as the “lungs of the world" however there is no scientific basis for such a claim as tropical rain forests are known to be essentially oxygen neutral, with little or no net oxygen production. ^[4]^[5]

[edit] Conservation

By speaking with the local people living in, and around, the rainforest, conservationists can learn information that would allow them to best focus their conservation efforts 3.

Another way conservation has become the most economically beneficial option is through carbon credits. Under the Kyoto Protocol, countries must reduce their emissions of Carbon Dioxide by 5% below the 1990 levels before 2012. Countries can meet their mandatory cuts in emissions by offsetting some of those emissions some other way. Through conservation or reforestation of the rainforest, countries can receive carbon credits.
