Why does the Amazon fire affect the world?

Amazon rainforest is located in the Amazon plain of South America, covering an area of 5.5 million square kilometers. Rainforests span nine countries: Brazil (accounting for 60% of the forest area), Colombia, Peru, Venezuela, Ecuador, Bolivia, Guyana, Suriname and France (French Guiana), accounting for half of the world's rainforest area and 20% of the global forest area. It is the largest and most diverse tropical rain forest in the world. The Amazon rainforest is called "the lungs of the earth" and "the green heart".

As the largest rainforest in the world, Amazon is an important carbon storage place to slow down global warming. It has about 3 million species of animals and plants, and it is a veritable "lung of the earth". However, new spatial data show that the number of fires in the Amazon rainforest has reached a record high this year, with an increase of 84% compared with the same period in 20 18.

According to the Amazon Environmental Research Institute, there was no continuous severe drought in the Amazon rainforest this year, and fires were mostly caused by human activities. In order to expand the land area for grazing or farming, people cut down the rainforest and clean up the site by burning trunks, branches and leaves. These activities caused the fire to spread to uncultivated areas.

According to the latest data released by Brazil's National Space Research Institute, the number of fires in the Amazon rainforest reached a record high this year; The agency said that since the beginning of this year, satellites have detected more than 72,000 fires, an increase of 83% over the same period last year.

Fires in tropical rainforests generally originate from nearby pastures and farmland. But in fact, there are also fires in tropical rainforests. There were serious fires in the Brazilian Amazon rainforest in 1997, 1998 and 2005. 90% of fires in the Amazon occur in dry years.

Amazon rainforest, the largest forest in the world, is known as the "world kingdom of animals and plants", with dense forests and a wide variety of animals and plants. Amazon rainforest area is the largest rainforest area in the world, which can consume a lot of carbon dioxide and prevent climate warming. The forest area is also rich in animal and plant resources, with 3 million species, including 6.5438+0 million aborigines.

Compared with 400 years ago, the forest coverage of Amazon rainforest has been reduced by half. If nothing else, the ozone layer will definitely increase because of the reduction of forest area, so the Amazon fire will definitely affect the world.
