Agree with everything, but not "China, the second worst polluter".  You are suggesting that CO2 is pollution, which it is not (hopefully a small slip on your part because the greenies are always calling it pollution) .  In terms of man-made CO2, China is in first place by a wide margin, and continues to expand its lead over the U.S., which is in second place.  In 2013, China's share of worldwide man-made CO2 emissions was 26% while the U.S.A.'s was 14% (link below).
