Just quick note - this whole "burning amazon forest, earth lungs" is fake bullsh!t and people who don't know sh!t about trees believed it (which is 99,9% of this planet).
So the thing is that cutting trees down is actually a good thing, fvck it, even if those trees burn its a good thing for the planet.
Old tree is using more oxygen than it generates. Young, healthy trees are generating more oxygen and clean the air in general.
Old trees (most types) are useless for air we breathe.
