Basically... A lot! Just to have what effectively amounts to a painkiller. Now don't get me wrong, those are great but you know what's better? Solving the issue that causes you pain to begin with.

I know something better and it's solar powered: Trees!

Trees are great for other reasons, but they grow far too slow to capture significant carbon. The fastest natural carbon sinks are algae.

I say, we damn up all of the arctic circle, propagate Azolla there, kill it off and sink it every season. Nature did it once! We can do it again!

But think of all the space that would take! If you replant forests where are we going to put our superhighways and parking lots?
