So.... all we have to do to save the earth is to collect carbon dioxide from the atmosphere by cooling the planet to about -80C. Or only -60 if we bump the pressure up to about 150psi. :smash:

Humans need a balance of oxygen in the atmosphere, plants make oxygen, plants need carbon dioxide to make oxygen. It takes a lot of plants to make enough oxygen for 1 human, more humans more plants. The planet doesn't need either, it doesn't even need an atmosphere many planets don't have an atmosphere they survive just fine.

Yes indeed, It is funny when people say we have to "Save the Earth". Like we have any say at all about the future of the universe or the Earth. When we are all gone, the bugs will carry on, repairing all of the changes we have made to it. Returning it back to the natural state.

But, maybe this IS the natural state. Who is the one to define "natural"? And really, what is the difference between natural and super-natural? Didn't the super-natural occur naturally?
