Seems the five biggest cities are mostly in the East, not the West. In fact, it lists the micrograms for LA as being 36 and New York as 22 and this was in 2002. I guess you could say Cairo is West, but it certainly is not in North America. Trinity, better have some real facts about the real polluters. Your generalization is false because it lacks chronological order. Look at your own website you gave; the list given is back in 2004. The references given below in footnote 2 shows China is a greater pollutant than America. Now, what is the UN going to do about it? Tax America with emission cap and trade and reward the Chinese by non-interference. What a great policy to end human pollution, you don't want to tick off the military power that has no concern about its own human rights violations.
