Oil drilling dangers to environment

BP's Macondo well blew out on April 20, 2010, killing 11 oil rig workers employed on the Deepwater Horizon drilling rig and pouring millions of gallons of crude into the Gulf. After the disaster the oil and gas industry spent millions of dollars trying to increase the offshore environment safety. But in spite of the obvious progress in development of the upgraded oil spill response systems the safety experts claim the measures taken are still far away from being satisfactory. Even if oil companies cooperated to develop systems for containing blown-out subsea wells, they have not been tested in realistic emergency conditions.
