Logs lay at a wood mill surrounded by recently charred and deforested fields near Porto Velho, Rondonia state, Brazil. The Brazilian Amazon saw 30,901 fires in August, the highest for the month since 2010, according to Brazil’s National Institute for Space Research, drawing international criticism over the government’s approach to environmental issues and its pro-business agenda.

While many of the recorded fires this year were set in already deforested areas by people clearing land for cultivation or pasture, Brazilian government figures indicate that they are much more widespread this year, suggesting the threat to the vast ecosystem is intensifying.

A truck carries logs amid forest fires along the road to Jacunda National Forest near the city of Porto Velho in the Vila Nova Samuel region which is part of Brazil's Amazon. Critics say the large number of fires this year has been stoked by President Jair Bolsonaro’s encouragement of farmers, loggers and ranchers to speed efforts to strip away forest.
