Yes that is a great solution if we had infinite space and time also if we weren’t concerned about the natural world and were happy to destroy all the biodiversity and unique biomes by converting into forests. Oh and if it would actually work of course, but that doesn’t matter in feelgood fantasy world.

I love trees, I’ve volunteered planting trees and donates to woodlands and all sorts of things but they are not going to save us from the mess we’re in. They’re also not as simple as they should be, management is crucial as there’s a surprising amount of things that can go wrong on a large scale which would totally fuck the environment - especially with foodweb issues and soil chemistry.
