You've brilliantly summed up the whole mess, imho.
I mourn the lost workers, the birds and other wildlife, and the coastal flora.
But, the image of the root of the problems is fascinating; beautiful.
Odd how that works.
Your words work wonderfully with the image.
Thanks for sharing.
This is really thought-provoking and resonant and masterfully succinct. This conveys, for me, the beauty of an oil spill, a picture you don't want to be real, but which in a fantasy setting -a canvas or dream - would be exquisite. I think the only thing I'd change are your two "its" since you can make your poem far more imagistic by denoting what the "it" is. On the other hand, if you want the poem to remain amorphous like a dream, then the "it" is probably apt.
