Removing CO2 is shooting ourselves in the foot, for without it plant life is slowly snuffed out.

But, I'm highly skeptical at our ability to even do it. Maybe on paper or a computer program we can, but realistically, how does one reach into an immeasrable amount of "air" and selectively snatch out the CO2?

Might remove it over an amout of acreage, but what about a distance away? The air/area in which it is theoretically removed is replaced almost immediately by the surrounding air, as natural systems seek to always maintain equilibrium/homeostasis.

High concentrations will seeek out low concentrations and vise versa, to achieve balance. Not rock-et science.

We neither know from where the wind comes, nor where it goes.
