Oil Spill in Gulf of Mexico

Please clean up the Gulf of Mexico. If you don't then all the fish will die and then all the fish will have certain death. Here's my plan:

1. Put a dam in front of the Gulf so the oil can't escape while pumping.
2. Put rock or a big giant plug in front of the hole so the oil can't escape.
3. Take the oil water to the water works. There, they will make nice fresh salty water for the ocean.
4. Drive back to the Gulf and put all the clean water back into the Gulf.
5. Lift the dam out of the Gulf so the water can flow free back into the Gulf.

Now the water is clean and all the fish will not die.
