If the saboteur-in-chief succeeds in cancelling the Clean Power Plan, one way to compensate for the damage is to plant 10 billion trees, covering 40,000 square miles with forest.

Planting so many trees is easier said than done. What's more, for the trees to take the intended amount of CO₂ out of the air, it is not enough to plant them. It is necessary that they survive and grow for many years. That is hard to assure, what with local disasters fueled by global heating threatening to kill them and increased CO₂ levels slowing the growth of plants.

Is it possible even to find that much land on which to plant trees?

Then there is the point that the Clean Power Plan doesn't go far enough.
