It isn’t just the trees that matter. It’s the rest of the forest ecosystem around the trees. Reforestation is still a great idea as part of a larger plan to restore the atmosphere to and global temperatures to what they were, but it isn’t a silver bullet. There is not one place in the world where you can plant a bunch of trees and declare mission accomplished, but you’ll want those forests there flourishing and absorbing carbon dioxide when we do neutralize emissions.
