"Another result of our study is that for the first time, we can quantify the amount of oil residue that ends up in seafloor sediments after a “natural” oil spill. To compare the amount the oil in the Santa Barbara sediments with a figure people might understand, it's equivalent to 8 to 80 times the oil spilled in the Exxon Valdez accident. But our study by no means is a direct comparison on the overall fate and impacts of the Exxon Valdez spill and the Santa Barbara seeps. "
I think the last point is the salient one here. Nothing can really compare to the kind of effects we see from a concentrated, uncontrolled spill like the one in the Gulf right now.
It's all cost/benefit to me. Yes, offshore drilling adds to the economy, creates livelihoods & reduces our reliance on foreign sources. But does it do enough of that to make risks like this worthwhile? We're talking about economy & livelihoods with this, as well, and well beyond that in terms of the natural environment & ecosystem.
To me, it's tougher than most are making it sound. It has really given me pause for thought as far as my support of offshore drilling. I know that, at the very least, I'll get a little queasy if I hear one more giddy cry of "drill, baby, drill!"
