After the Amazon rain forest, the rain forest in Africa is also burning. What's going on here?

Fires in Brazil's Amazon rainforest have been raging for several days. The smoke from the fire once enveloped Sao Paulo, Brazil, and the whole city seemed to turn from day to night. According to statistics, in 20 19, the number of fires in the Brazilian Amazon rainforest set a record.

Most of the rainfall in the Amazon region is generated by the rainforest itself, but with the disappearance of trees, the rainfall is also decreasing. The large-scale destruction of the tropical rain forest by the fire makes the rain forest drier and drier, forming a vicious circle.

The overall precipitation in Brazil is less this year, and August is just the dry season of the rainforest. This "fire season" generally reaches its peak in September and finally lasts until the end of 165438+ 10.

According to Washington post's report on August 2nd 1 day, according to INPE data, the Brazilian Amazon rainforest has experienced 74 155 fires since June this year, an increase of 85% over the same period last year.

In the severe drought year of 20 16, the number of fires in the whole year was 67790. Why does the Amazon rainforest catch fire? It burned for three weeks? According to netizens, the fire was caused by a new logging order issued by Bolsonaro.

It leads to a sharp increase in logging rate, and excessive logging leads to a decline in forest self-healing ability. In fact, there have been fires in the past, but most of them can be extinguished naturally through the self-regulation of forests. But this year, the logging rate is too high, and there are too many fires, large and small, which eventually led to this fire!

Detailed loss data will not be counted until the fire has completely subsided, but from the current situation, the situation is not as bad as the most extreme situation.
