I think we've all heard more than enough of ignorant American politicians' hubris to last us a lifetime, thank you, and there's plenty more to come. The problem threatening the planet is carbon emissions from energy consumption. By your own statistics, that problem is overwhelmingly down to the activities of China (one-child policy), the US (only 5% of the world population, low birth rate) and Europe (under 10% of the world population, low birth rate). Other countries with big populations are not in the same emissions league. The implication of putting the blame on population increase is that you're fingering countries with high birth rates. That may well lead to other issues, but they're not the ones producing the carbon emissions, are they?
