Well, China has been working hard to catch up to the US in many areas, why not this one? As a response to Zou Ji’s comments (he of Renmin University and quoted in the article below). "When we become richer and richer, and feel safer and safer, then people will have more time and more resources to pay attention to something not directly linked to themselves", you need to realize that the costs of retrofitting your economy to both stop polluting as well as clean up your mess will be prohibitively expensive. China , both as a state and its citizenry, would be far better served by its leaders being more forward thinking. Additionally, the long-term health of their eco-system, of which their bodies are mere extensions, is something that’s hard, and expensive, to buy back. This attitude is much like, knowing you have cancer, to wait until you’re richer so the financial bite is less painful. Anyway, as is so often the case, Grist says it so much better than me.
