I really care about the environment but just cant see the priority of carbon emissiion reduction over other issues. There are many proven more acute air pollution issues with immediate health effects that should get dealt with first. The challenges of world hunger, access to fresh water, conservation of soil all seem more urgent problems than carbon dioxide emission reduction. Sure we should do it all but in reality there has to be priority. While i can not argue carbon dioxide emissions dont contribute to global warming, mans contribution might not be as significant as natural processes processes. It would be a shame to spend billions on C02 reduction and miss the real immediate threats.
