Nor should they. Stopping offshore oil production because of a big nasty spill is a bit like vowing to never ride in a car again because your best friend died in an auto accident. Yes, what happened was horrible, and maybe this is suddenly a risk you would rather not deal with anymore, but tragedy doesn't change reality. Oil is a requirement of our way of life just like timber and food, until something exists to replace it, and we aren't anywhere near that yet.
