//a single PIN HEAD size of oil in a larger-than olympic size pool (just the Gulf region) is dangerous//
Well if that is the situation then no, but it does not look like that is the situation out there. No one knows the vlolume of oil coming out down there, but the estimates have been raised yet again.
Look your math is fine, but I look at what is going on from the satellite photos and other more close up images, and as I see it the magnitude and scale of it, it is not adding up for me.
You are forgetting the about the effects of the oil and the dispersant Corexit combined.
What the Corexit does is keep the oil from binding together so there is no slick.
But the Corexit goes right thru skin etc and it takes the oil with it. Once in the body it ruptures cells including red blood cells. Now anything that breathes water and swims thru that is probably going to die, not to mention porpoises and whales.
Will the Earth fix it? Yes eventually, the question is how long.
So yes I am worried about the ecosystem of the GOM or least large segments of it. It is no doubt that large parts have already been killed. How much more will be killed and how long will it take for a true recovery to happen in the Gulf is the question for me, and that all depending if killing the well is successful.
You are certifiable..
