When you break it all down things really are comparable. No, try again. Carbon sinks and total pollution output per annum illustrate how absurb your point is. And again, if the US doesn't do it, someone else will fill the void, and quite possibly with lower standards. Well, when if that day comes, the world community will be sure to criticize them, when they take your place as the world's largest single polluter. But for now, let's stick to REALITY shall we. I'm not saying it's perfect but to try and force restrictions that hurt an already weak economy, you must be joking. Surely you must be joking, my friend. If nothing is done now to halt The Greenhouse Effect/Global Warming, cyclical economic difficulties now will seem like nothing in comparison to those 25 years from now, when drought, acid rain, sea level changes/flooding, UV radiation, etc. really come into their own. The signs that we're seeing now with the environment are just a taste of what is to come if the emission of greenhouse gases are not curbed immediately by all nations. The carbon sinks is just an excuse and isn't a valid point. If pollution is the worlds problem then how can pollution filters belong to a single country? Carbon sinks are HUGE. Together with cutting pollution, they are the keys to reversing the effects of The Greenhouse Effect/Global Warming. And contrary to what you say, carbon sinks can and do belong to a single nation (in some cases). Case in point, Canada and its vast forests; our respective governments (federal and provincial) have decided to protect some Old Growth Forests, chosen sustainable forestry practices (there is room for debate here - but it should be in another thread), and actively engaged in silverculture (replanting); in contrast to cutting everything tree down which is our option as a sovereign nation (the last I heard, the Philippines was 95% deforested). THIS WAS OUR CHOICE; thus, all the acclaim and criticism (some say we should being doing more - fair enough) belongs to our nation. Similar practices exist in the US, but the sheer size of Canadian forests FAR OVERSHADOW those found in the US. Thus, it would be wise to give the appropriate credit where credit is due; instead of making illogical and absurd comments like "carbon sinks is just an excuse and isn't a valid point."
