In a related note, I researched a little about ship sinkings in the Gulf of Mexico during World War II.
- 42 ships were attacked by U-Boats in the Gulf of Mexico during World War II.
- 25 of these were tankers.
- 28 of the 42 ships were sunk
- Another 4 were sunk in the GoM in 1943 (2 tankers and 2 freighters).
Although there no doubt was environmental damage, even with all that oil being spewed into the Gulf of Mexico, it wasn't killed.
I post this not to minimize or somehow negate the significance of the current oil leak, but it does provide some cause for optimism.
