I dont think people like you realize that in the significance of the entire planets oceans this spill is damn near meaningless, estimates put more oil seeping into the worlds oceans on a daily basis than is leaking from the GOM. The difference is all of this oil is in one spot in a relatively small body of water, the Gulf of Mexico.
The ecological damage will be substantial and long lasting in our area, as far as its negative impact on the pacific or indian oceans it will be almost nil...impacts on the Atlantic as a whole will likely be minimal.
