Where can I learn more about the costs and challenges of thoughtful reforestation, and the key differences between the responsible and irresponsible sort? (Just popping in to ask because it seems like you might know). I'm interested in doing some work in this space but don't have any background.

Hmm… can’t point to one specific book, but there are lots of links. You can google “reforestation monoculture” and “reforestation native species.” This article is a great place to start: https://e360.yale.edu/features/why-green-pledges-will-not-cr... It doesn’t get into the granularity of the costs, but highlights that the basic issue is countries are still hoping to make a profit off these “carbon sinks” by planting easily usable timber - aka monoculture - which greatly diminishes the benefits of forests and leaves them vulnerable to blights and other disasters.

Thank you very much!
