Discussion Post You might remember the most recent major American oil spill, the Deepwater Horizon (Links to an external site.), which cost 11 lives and leaked 210 million gallons of oil into the Gulf of Mexico. There have been dozens of smaller oil spills since then; oil spills are so common they don’t always make the news. The oil companies involved in Deepwater Horizon still have not paid for the damages, and, like the Exxon Valdez spill, the oil is still washing ashore in some places. In many cases, including Deepwater Horizon, the majority of the cleanup is being paid for by you, the taxpayer. (Links to an external site.)
