I don't have facts and figures to dispute that, but in general, afaik, usa has an immensely greater environmental awareness and respect than China. Certainly we make plenty of mistakes or arguably poor decisions. Certainly there are Chinese folks who understand that respect for the environment is a key component to quality of life. But in general, the overarching vibe I take from china (based on what I read and from talking to some folks who have visited there), China doesn't give a flying F about environmental issues unless they are bitten hard in the ass by them. Witness their legendary air pollution, the breakneck pace they are building coal fired power plants, the 3 Gorges Dam debacle, the entire cities they've built that are completely unoccupied. Maybe I am wrong but afaik, China is a cautionary tale for humans and planet Earth.
And, in true chinese fashion, it is a question of yin and yang- opposite qualities within the same being. In addition to the environmental atrocities they are know for, they also pioneered acupuncture, chinese herbal medicine, the gentle arts of nature appreciation.
