Re: Oxygen - Trees vs. Algae
[ QUOTE ]
Do trees really contain a significant amount of oxygen? People say if our trees are cut down then our oxygen is gone but isn't most of our oxygen from algae?

Yeah I think most of it comes from plankton. But even if plankton does 90% of all the photosynthesis in the world and trees do 10% then trees are still very important to the ecosystem.
