Besides producing this riverine sea, the deluge also nourishes the largest stretch of rain forest left on Earth. One-third of the remaining rain forest was in the Amazon basin and fires had consumed about 10% of it, an area twice the size of California.
The Amazon basin has fires on a regular basis.
