The rainforests in the Amazon region are called the Amazon and are considered the world's most powerful resource. It is not for nothing that these forests are called “the lungs of the planet”, because they produce about 20% of the world's oxygen. These forests are more than 50 million years old.
They were named after the Amazon River. The tropics occupy about 2.5 million square meters. km (this is 9 times more than the state of Texas) and represent the largest rainforest in the world.
The biosystem of the Amazonian forests includes: 40 thousand species of flora, 500 species of mammals and 300 species of reptiles, as well as a large number of insects (only butterflies are more than 1800 species). The number of birds that live in the tropics of the Amazon represent one third of the total number of bird species on earth. The most famous symbol of these forests is the toucan.
According to the observations of researchers, due to the development of industry in nearby states, approximately half a hectare of tropical forests is cut down every second. The rainforest of the Amazon is home to 250, 000 Amazons, among whom there are 215 ethnic groups who, in turn, speak 170 different languages. Forests receive about 240 cm of precipitation annually, and they return about 50% of the resulting liquid back (i.e. into the atmosphere) due to evaporation.
The world's largest fish - Piraruku, reaching impressive sizes (up to 2.5 m in length) and having a record weight of 250 kg was caught in the Amazonian tropics.
It is worth noting that the number of fish species that live in this region exceeds the number of fish species whose habitat covers the territory of Europe. Unfortunately, the protection of the Amazon rainforest is a significant challenge. The good news is that over the past ten years, actions aimed at preserving the protected area have significantly increased.

The structure of forests includes 4 layers, each of which, in turn, constitutes a unique ecosystem with flora and fauna inherent only in it. Five centuries ago, in the Amazonian tropics, the indigenous population huddled - about 10 million. Aborigines. Today, tropical forests still preserve many endangered species of animals, for example, the golden lion Tamarin, the hyacinth macaw parrot and many others. dr.
