Good point - with x amount of drilling activity, especially underwater (!?!), one has to factor in a certain amount of problems and accidents. We are all responsible, although I do think BP/Halliburton are still more immediately responsible - it's the global demand for oil that supports the risktaking of underwater drilling. We are truly scraping the bottom of the earth's barrel - that's why we're on the ocean floor and deep in tar sands, trying to get what we can.
