And apparently back when what was eventually to become anthracite was first being deposited, there was as high as 30% to 35% oxygen in the atmosphere. Today it is about 20.8%.

O2 kills, its a poison to animals, and algae probably caused such high concentrations of the stuff. Now Obama wants us to make more algae. We better alert the environmentalist and stop this before it's too late! :shock:

Yeah I'm waiting for the EPA in their infinite wisdom to outlaw o2, & try to remove as much of it as possible from the atmosphere. :lol:
