Yeah, deforestation is another problem they have to worry about. Having 1.3 billion under you may make Chinese leaders feel good in front of other world leaders. However,it sure is a source of big headache. All these could go out of control. In China, social and environmental problem tend to take a life of its own, frequently interacting with one another, and become unstoppable even with bullets.
If I remember correctly I think the Chicom governments response to the problem was to require every citizen to plant like 12 trees a year.
What a nut-job idea.
