    Major causes of record fires sweeping across the Amazon rainforest this month include the dry season and human activities, according to research institutions and media reports.

The rainforest is typically wet and humid, and the frequency of fire activity usually rise each year since July — the onset of the dry season, and peaks in September and decreases in October as the rainy season approaches.

However, data from the Brazil’s National Institute for Space Research (Inpe) showed that the number of forest fires in Brazil soared by 82 percent from January to August this year from a year ago, and over half of those fires occurred in the Amazon rainforest. A total of 71,497 forest fires were registered in the country in the first eight months of 2019 , up from 39,194 in the same period in 2018, the Inpe said.

Human activities have led to the recent increase of fires, some experts have noted. The view was echoed by many, though they were divided over who actually conducted the activities. On Friday evening, Brazilian President Jair Bolsonaro pledged “zero tolerance” of environmental crimes, adding that the Armed Forces troops and resources will be mobilized from Saturday to help put out the fires.

Earlier this week, Bolsonaro blamed non-governmental organizations for increasing wildfires in the Amazon rainforest in the country’s north. His claim was refuted (反驳) by environmentalists, who argued that the surge of fires was a result of increasing deforestation and burning fueled by the governments anti-environmental policy. Alberto Setzer, an Inpe researcher, told local news site G1 that all the fires are results of human activities some accidental while others intentional.

Scientists and environmental groups are worried that the fires will aggravate climate change crisis and threaten biodiversity. The emergency has now transcended (越过) Brazil’s borders , reaching Peruvian, Paraguayan and Bolivian regions.
