An employee clears seaweed from the French coastline at Saint Michel-en-Greve, Northern Brittany, July 7, 2010. Since mid-2009, French authorities have continued efforts to remove thousands of tonnes of the noxious green algae from these tourist beaches after reports that the seaweed is emitting toxic gasses.
