The rainforest

What is a rainforest? Definition:

As rainforest are evergreen forests with annually high precipitation amounts. Based on the climate zone in which the rainforest is located, a distinction can be made between two different types of rainforest zones:
(1) Tropical rainforests: lie north and south along the equator.
(2) Moderate rainforests: lie above or below the northern or southern tropic.

The dense vegetation, combined with the frequent rainfalls creates for many animals an optimal habitat (biotopes). No other ecosystem has so many different species in a small space, including some endangered species such as gorillas, parrots, orangutans, chimpanzees or tigers. Man-made destruction of the rainforest (slash-and-burn, deforestation, monocultures) will inevitably lead to the extinction of these rare species in the foreseeable future.
Although rainforests make up only about 5% of the Earth's surface, they account for 1/3 of global oxygen production. In the context of photosynthesis, plants absorb the greenhouse gas carbon dioxide from the air. As a result, oxygen is produced as a waste product and is released to the environment. Especially considering this important aspect, the world's rainforests are - even in the interest of human beings - to be regarded as particularly worthy of deterrence, because they not only minimize harmful greenhouse gases in the atmosphere, but are also an indispensable prerequisite for life on our planet in the long run.
The tropical rainforest areas are divided into three major rainforest zones: the African rainforest area (Central Africa, Madagascar), the Southeast Asian rainforest area (India, Indonesia, Malaysia) and the Central American rainforest area (Central America and the Amazon region). The satellite image of the rainforest along the Amazon illustrates why the rainforests are also known as the "green lung".

Typical features of a rainforest

constantly high humidity: during the day about 80% -90%
high rainfall: partially> 3000mm per year
temperature: All year round between 24 ° C and 32 ° C
missing seasons: instead day and night rhythm
dense vegetation: evergreen, hardly any free space
ground: low in nutrients, very thin layer of humus
Storied: layered structure of the vegetation
biodiversity: the highest biodiversity of all ecosystems
