Should be pretty easy to plug the BP oil spill.
This graphic from the WSJ says it all. Look at the little "person" at the bottom. The well itself goes another 13000 feet down from here (already 5000 feet below the surface).
A few oil spill domains are available. By signing up for a free membership on HotNameList, you can get access to the full list.
I like: LargestOilSpill.com
Happy Domain Hunting!Jorge
