trees are only a co2 buffer, they don't make it dissappear. and trees require water, and the burn up (which puts the c02 back also)

Even if we had to replant the trees every decade, that would only be 5 billion dollars a year, forever. Trivially affordable at "world power" scale.

Lack of water is a much more real blocker, with space not far behind.
