Peace (in our time) asks: "The atmospheric percent of O2 has been at 21% for what seems like ever. Why is that since we're killing off the Amazon rainforest and polluting the hell out of our oceans and thus killing O2 producers?'

ans: The best O2 conversion areas are coastal marsh lands, not open oceans. Actually, most of the crap we dump into the oceans in broken down by microbes. The solid material falls to the bottom where very little (if any) life exists. As to the Amazon rain forest, it has been under attack for at least 400 years and yet only 5-7% is gone. This is in direct conflict with the opinion of some Environmentalists who have been saying "15% of the world's rain forests are destroyed each year"(!) That just ain't true.

Don't get me wrong. I hate pollution, polluters and habitat destruction. I have the same feeling when it comes to propagandists and other professional liars.
