Well, the rain forest is one of earths primary air scrubbers and oxygen producers. With all the deforestation and now the massive fire, we loose a good percentage of that so certainly cause for concern.
Nearly all vegetation absorbs CO2 and carbon emissions converting it to O2.
Make no mistake, mans encroachment in these places, making concrete jungles, does have an impact worthy of alarm. Not that the global warming activist and fascist have basis of fact, we need conservation starting now,
What we have in all natural resources is under strain for the 7 billion + humans, that will exceed 8 in a decade.
