The raging fires consuming God knows how many tens of thousands of acres of Amazon rainforest were deliberately set by ranchers to clear land for cattle-grazing, knowing full well that the the ultra-conservative government of Jair Bolsonaro (aka “Tropical Trump”) would tacitly approve.

Destruction of just 3% of the Amazon could have a devastating worldwide effect.
