Cause of fire: fires are all man-made. Experts point out that unlike natural fires in grasslands and forests, fires in the humid Amazon rainforest are mostly caused by humans. In order to occupy more land for grazing or farming, people cut down the rainforest and clean up the site by burning trunks, branches and leaves. The vegetation ashes left by burning can be used as nutrients to nourish the land.

Experts believe that only excessive logging can explain this phenomenon. According to the data of Brazil's National Space Research Institute, from 2065438 to July 2009, the area of Amazon rainforest was cut to 2254 square kilometers, up 278% year-on-year.
