Now, about a week out from the oil spill in southern California, wildlife and environmental experts are attempting to assess the damage done to the wildlife population. The spill was estimated to have leaked anywhere from 31,000 to more than 120,000 gallons of oil into the water off the coast of Orange County. There are several ongoing investigations into the cause of the leak, however, many suspect that old and potentially cracked pipes are to blame. The spill has left fish and birds dead in petroleum along the shore and contaminated the wetland areas. In an attempt to clean up the mess, many beaches have been shut down, and more than 2,000 feet of protective booms (temporary floating barrier to contain the oil) have been deployed. An additional 3,150 gallons of oil have been removed from the water. The spill is inspiring several environmental groups and state senators to call for the end of oil drilling off of the California coast.
