I don't think I'm alone in thinking that, sadly, maybe something like this happening is necessary to shift the American general public's view on the subject of oil.
Mind you, I've actually been hoping for something for the US resulting from the effects of climate change, rather than an industrial accident, because spin doctors will try to convince everyone that this is an isolated incident which will never be repeated. Of course it's not that I'm wishing for such disasters in themselves - I just believe the US needs to feel its fair share of the Earth's environmental pressures if it is to really change its ways, because what happens halfway around the world may as well not exist.
Here in Australia we can pretty much match you, at least on a per capita basis, on carbon emissions and environmental destruction, so it's not some holier-than-thou position I'm taking. But at least we've been feeling some of the side-effects of the current behaviour of humanity, with our agriculture suffering from years of the worst drought on record. And the bushfires of last year were a highly lethal result of such extreme and prolonged weather patterns.
So even in the regional and rural conservative heartlands the merits of environmentalism are becoming widely appreciated. We're still not doing much to actually go green, but at least there isn't quite such entrenched ideological opposition to it.
Anyway, even though this Gulf catastrophe is a massive accident of corporatized industrialism rather than a predictable ongoing by-product of it, at least it's something that could really help make oil less fashionable.
