The 2020 year was marked by burning in the Amazon (Fig. 2). Up to September, 72,292 outbreaks of fires were observed by INPE's Active Spot Monitoring (INPE, 2020b).
We have already noted that the Amazon is under great pressure from deforestation and fires. But how does this impact the environment? According to Werth and Avissar (2002), the climate in the Amazon responds strongly to deforestation. Thus, the greater the deforestation, the shorter the rainy season, and the region will experience greater periods of heat and dry climate.
Also, Oliveira et al. (2013) showed that the expansion of agriculture in the Amazon may not be beneficial for the farmers themselves. Changes in the region's climate can decrease agricultural productivity by 30%. According to the same author, deforestation in an area of the Amazon rainforest to be replaced by a set of agriculture and pasture is also not viable, with reductions in productivity.
Other problems also occur with deforestation, such as habitat reduction, and in burning, the mass death of animals occurs; in addition to the transport of ashes by the wind to other regions, which can cause respiratory damage and even dark-colored rains.
