Fred Pearce's A Trillion Trees is great eye-opening education on the action and importance of trees and forests in the Earth's overall biosphere and hydrosphere, the practices and policies that threaten that importance (contributing to local and possibly global climate changes), plus plenty of high-profile plans mitigate or reverse the damage that don't seem to work so well and some quieter ones that do.

There's a lot in there, and it can feel like a lot to absorb, but it's all woven together nicely and presented in a story-telling style that I found easy to read and follow. Even if I don't remember every event and concept presented, I did come away with a significantly expanded understanding of the important role trees and forests play in Earth's climate, how the effects of that role has changed over time in response to extensive logging and deforesting, replanting projects, and both government and indigenous approaches to land and forest management.

If you're interested in and/or concerned about Earth's climate and water cycles, how they've changed over time, and what we might be doing to them, A Trillion Trees feels like a must-read.
