The Gulf of Mexico oil spill is expected to become the biggest oil spill in U.S. history and an environmental disaster far worse than the “Exxon Valdez accident of 1989.” 210,000 gallons of oil continue to pour into the gulf each day and the slick is now roughly 130 miles by 70 miles wide. As the spill nears the shoreline, experts warn that wildlife, beaches and the fishing industry are likely to be devastated. This hour, we’ll look at how fishing communities are coping with the impending disaster. And, talk about the effect of the spill on future U.S. energy policy. Our guests are Diane Wilson, environmental activist and former shrimp boat captain, and Lisa Margonelli, director of the New America Foundation energy initiative.
