|Oil Barrel in Lake Michigan|
Gulf Coast activists feel differently. While "only 26% of the oil" may still be visible on the surface there has been no accounting for subsurface oil and dispersant or chemicals that have sunk to the bottom. There is little science available about what happens with those pollutants nor what happens when so many "little hydrocarbonoclastic organisms" are eating oil and sucking up oxygen. Perhaps adding to the annual dead zone in the Gulf caused by algae blooms fed by run off of chemical (hydrocarbon based) fertilizer from Midwest farms (it arrives every summer down the Mississippi). This year's dead zone is reported to be "the size of Massachusetts."
