More bad news (at least, it is news to me): the dispersant BP used is http://en.wikipedia.org/wiki/Corexit#Toxicity_and_alternatives, which is toxic to humans. Because not only does BP have to pollute the environment by not fixing the leak, they have to try to kill/maim every living thing in the food chain.
I love their response too.
EPA: Use a different dispersant before you kill [censored] everyone
BP: Everything we do is in compliance with what the EPA tells us.
EPA: USE A DIFFERENT DISPERSANT NOW!!!
BP: *still dumping toxic chemicals in the ocean* We've never disobeyed the EPA
EPA: Dude, you have thousands of gallons of the non-toxic kind at one of your lots, can't you use that?
BP: That stuff's toxic, obviously the EPA doesn't know [censored] about protecting the environment.
