“In the Amazon, nothing is adapted to fire,” saysa researcher William Magnusson, a specialist in biodiversity monitoring at the National Institute of Amazonian Research (INPA) in Manaus, Brazil. It’s not like in Australia, for instance, where eucalyptus would die out without regular fires, he says. A growing number of manmade fires have plagued the Amazon in recent years, imperiling the ecosystem. The rainforest is not built for fire.
