Is enough being done to prevent environmental disasters?
BP's chief operating officer Doug Suttles said the 98-tonne concrete-and-steel containment box had to be moved, after ice-like crystals began accumulating inside it. He said BP's engineers hoped they could find a solution to the problem.
Some 5,000 barrels (210,000 gallons) of oil a day has been leaking for 19 days from the well, 50 miles (80km) offshore, since an explosion destroyed the Deepwater Horizon rig last month, killing 11 workers.
Are you affected by the oil slick, or have you seen it spreading? Is it right for oil companies to foot the bill? Should we all take responsibility for cleaning our environment? What measures should be taken to reduce the number of environmental disasters?
