Far from isolated mega-catastrophes — such as the 1989 Exxon Valdez disaster in Alaska’s Prince William Sound — oil spills occur routinely around the world, causing environmental and economic damage, provoking investigations by regional governments, and often leaving the victims unsatisfied. Entering the words “oil spill” in the Google News search engine returned more than 2,500 distinct articles published in the last 30 days on the topic. At the top of the news right now is the 100-foot fountain of petroleum that smothered the Canadian town of Burnaby this week, after a pipeline was pierced by a road-excavation crew. Fifty homes were evacuated and the contamination spread to the nearby Burrard Inlet, a harbor and wetlands ecosystem home to a variety of marine wildlife, including four species of salmon. Experts told the Canadian Press that the cleanup will cost millions, and that the toxic effects of petroleum in soil, sand and water could last for decades.
