Re: How many trees do we actually need?
[ QUOTE ]
I have a weird question. How much flora is actually necessary to sustain comfortable levels of oxygen for people and animals in the world? How many acres of rainforest can we continue to bulldoze before we actually start running into an "oxygen shortage"? [/ QUOTE ] People would die from CO2 poisoning before we die from a lack of oxygen.
