On April 20, 2010, the Deepwater Horizon oil rig exploded, killing eleven workers and creating the largest oil spill in the history of U.S. offshore drilling, a spill that has despoiled the Gulf and its wildlife for long periods to come. But, this wasn't the first time British Petroleum and its cost-cutting practices destroyed parts of the natural world or endangered human life. Journalist Mike Magner has been tracking BP's negligent, cost-cutting path for years. From Alaska to Kansas to the Gulf, he's talked to people whose lives have been destroyed by BP's almost unparalleled corporate greed. 'Poisoned Legacy' is the story of the rise and fall of BP, a company that continues to put profit ahead of human life and preservation of the natural world.
