This is who I really feel sorry for: the fishermen. The sea life (shrimp, oysters, fish) is their livelihood. This is how they pay their mortgages, feed their families, pay their help. This is going to be financially devastating, as well as environmentally damaging.
hmm, I wonder what would happen if fire were introduced down there.???
Would it blow up, catch on fire...
or nothing.
If nothing, then ...can they weld, down that far?
If so, that would open up all kinds of other possibilities.
