U.S. Geological Survey
"The amount of natural crude-oil seepage is currently estimated to be 600,000 metric tons per year, with a range of uncertainty of 200,000 to 2,000,000 metric tons per year. Thus, natural oil seeps may be the single most important source of oil that enters the ocean, exceeding each of the various sources of crude oil that enters the ocean through its exploitation by humankind."
interesting, not a geologist, will look that fact up - but consider this: this is the
annual global net amount - it says nothing about to very important facts: rate and distribution of the natural oil seepage. If the crude oil enters the maritime ecosystem with a very low rate , than it can deal with it. There are microorganisms that can process oil , but not the amount we´re seeing here and not in on such a rate/ on such a short time scale. ( How could they, they´re not adapted to it)
Also, look at the uncertainty given here, it means that some very smart people knew that they got to be careful with that number.
@Airhead: all true , and i completely agree
@supervike: ah, another Daily Show fan - watched the show too, and if these numbers are correct, somebody in charge should think about revoking BP´s licence to drill
Edit:
Oops forgot to add:
Airhead , you´re mostly right with the losses for fisheries, but let me just throw in the following thought: crude oil contains a certain amount of natural aromatic hydrocarbons and polyaromatic hyddrocarbons - while these compounds aren´t very solubly in water in general, a certain percentage will enter the ecosystem, stored in the fatty tissue of fishes ( bioaccumulation ) , and might finally land on the dinnertable - and this stuff isn´t very healthy, and doesn´t just leave your body - it get´s stored in human fat cells too. I hope that someone from the EPA remembesr to check for that periodically over the course of the next year
