Gulf Oil Spill

You know, just as we hear "An accident causing an oil spill is highly unlikely". Look at what happened. This thing is massive and should have been stopped sooner. It has killed many dolphins and other sea life, is threatening delicate wetlands and one of our main sources for seafood. This oil spill has gone on far to long and is still unfixed. The experts from BP or British petroleum as my favorite high school teacher Mr. K Zisel once said are saying it could take up to 3 months. 3 months?! That's long enough to fill the entire Gulf of Mexico, get drawn into the current that flows around the entire world and kill all sea-life. Why can't they just dive down put a clasped piece of sheet metal around the leak and seal it with waterproof sealants? I hope it will be fixed now instead of too much later. It's been long enough.
