Big numbers on the ocean floor

The legacy of this century in the Gulf.
More than 3,200 oil and gas wells classified as active lie abandoned beneath the Gulf of Mexico, with no cement plugging to help prevent leaks that could threaten the same waters fouled by last year's spill.

These wells likely pose an even greater environmental threat than the 27,000 wells in the Gulf that have been plugged and classified as "permanently abandoned" or "temporarily abandoned."
