I don’t know much about the science or engineering behind the BP oil spill but I’m smart enough to know it is a calamity. When I read in the paper that it covers x number of square miles I cannot comprehend in any meaningful way the size or magnitude of the spill. This web-site invites the visitor to input their hometown into its engine; it then shows you the area the spill would cover if ground zero was your hometown. With recent disclosures that BP and the Feds might not get this under control until Christmas (!) and the approaching hurricane season, calamity might quickly become an environmental holocaust for the Gulf region.
