Me answering: well, phytoplankton make something like 65% of the oxygen we breathe so our air naturally is about 21% oxygen. The bad news is that over the last 150 years we have been emitting huge amounts of carbon into the atmosphere which is making our oceans (where the phytoplankton live) more acidic. We know that the phytoplankton is less healthy in the acidic ocean and we’re not really sure how much more carbon the oceans can absorb before the phytoplankton really gets in trouble. Nevertheless, we are not really taking the carbon emission problem seriously because it would make the ultra wealthy slightly less wealthy, and they’re the only people that matter when it comes to public policy. So I am sorry you will probably have to experience 140F degree weather in the summer. At least as the amount of oxygen in the air decreases we’ll all get dumber, so maybe we won’t be able to comprehend the suffering we have caused.
