Daniel P. writes: Apparently, the amount of oil leaking from the source is a lot greater than estimated so far. Recent numbers said that the amount of oil spilled would lie anywhere between 12,000 and 19,000 barrels daily. Those numbers have now been corrected and increased tremendously to at least 20,000 barrels, and up to 30,000 barrels of oil per day, according to The New York Times.
The German newspaper Frankfurter Allgemeine Zeitung (FAZ) even talks of up to 40,000 barrels a day (http://www.faz.net/s/Rub47C2F00B5F984DC2A4997324448B2EA2/Doc~ED1146D96CA1849D6B551FBD42C5AEF40~ATpl~Ecommon~Scontent.html).
If those numbers turn out to be true, then the amount of oil spilled every week exceeds the total amount of oil spilled during the Exxon Valdez incident in 1989.
