It´s sad to see how the Amazon are burning at the moment, and the goverment that can do most, Brazil didn´t do anything at first because the fire on rainforest clear the way for them to make crop fields, and farms for animals.
But, how the fire start? the most probably thing is local farmers start it, for the reasons I have already explained. These reasons aren´t enough to justify all the damage to the ecosistem and, even for the whole planet, because The Amazon Rainforest produce a high percentage of the oxygen in the world, even there are a big biodiversitywith unique species.
So in a nutshell the burning in The Amazon is a problem that involves everyone and every country.
