The way China is industrializing and the pollutants coming from lack of waste treatment they will not have to worry about over population. They will be killed off by their own industries and waste.
Looks like they do not want to put funds into waste treatment. Would rather spend the money on further expansion.
I lived in the Hudson valley region above Albany most of my life. Some years back they found that GE was polluting the hudson river with mercury from their capacitor manufacturing in Glens Falls. They clamped down On GE and shut down the river to fishing. They were suppose to be cleaning up the river but I do not know if they have or not. The mercury is located in the river bottom sediment.

Thanks JAP! We've come a very long way since the 50's when hazardous waste barrels started floating up form swamp burial sites. Lots has been done since that time.

You're probably right they'll be killing off their population with industrial pollution, but with adequate funds in place to make changes then pressure can be brought to bear.
