u kno what, i might be a little biased because i'm from china, but coal is a necessity of china(It's their primary source of energy) and it probably will be for a long long time. They are trying their best(as shown in the months/years before the beijing olympics). When I went their for the 2008 olympics(i live in st.louis right now), it was much better from when i went their in 2000. The black smoke and smog used to be there every day in 2000. But in 2008, i would only see it about once every four or five days. i don't blame you for thinking that china's enviroment is really bad, but people can't just expect them to suddenly go really green in the really near future.
