On a side note I don't get environmentalists. They complain about dwindling sea life yet don't seem to understand that the pillars of oil rigs that are underwater attract coral polyps and they grow to the size everyone is familiar with. And it's not just oil rigs. Sunken ships have also been taken over by coral which create a new environment. The same goes for planes that crashed in the ocean. So. . .instead of doing the obvious and taking some boats or even a small section of planes from the 'boat/airplane graveyards' and dropping them into the ocean to see what happens, the environmentalists think it's a good idea to take tires and string them along the Florida coast which did NOTHING to promote coral growth.
