Brown pelicans sit along the shoreline in front of oil containment booms at the North end of the Chandeleur Island in the Gulf of Mexico in Louisiana. The Deepwater Horizon, a BP leased oil platform, exploded April 20 and sank after burning. It has continued to spill large amounts of oil into the Gulf of Mexico nearly a month since the disaster struck. The oil continues to move closer to the shoreline threatening the marine life around the gulf.
