I wonder what kind of forest China is making? I was watching a really fascinating PBS documentary on Kanopy and it was talking about a lot of the planting efforts haven't been very good worldwide because planting a monoculture of trees doesn't do much and an old forest with tons of diversity stores twice as much carbon or more, which I thought was neat. So protecting existing forests is much better from a climate change standpoint. But either way, planting trees is better than nothing.
