Well, before we can even get into statistical analysis, we need to make sure the facts are accurate and dispositive in the situation at hand.Ummm, you have statistics like these:
Pollution carbon dioxide per capita (most recent) by country
Pollution municipal waste per capita by country. Definition, graph and map.
Until we have a concerted global effort to analyze climate change, we really don't know whats going on.
But, even though the data you provided shows America as the lead producer of pollution, we are still spending a disproportionate amount of resources to combat global climate change relative to the rest of the world.
