Kids play volleyball on an oil covered beach in Gulf Shores, Alabama, USA on 1July 2010. High waves and rough seas from Tropical Storm Alex have pushed more oil from the Deepwater Horizon Oil Spill on shore and have prevented clean up crews from working. The BP Deepwater Horizon oil spill, which began two months ago, is the largest in US history and continues to threaten wildlife, the ecosystem and the economy of the Gulf Coast as BP and government officials attempt to stop the flow and remove what has already been released. photo by Dan Anderson/ European Pressphoto Agency
