Oil from a broken pipeline coats four miles of the Pacific Ocean and shoreline at Refugio State Beach near Goleta, Calif., May 20, 2015, after a 24-inch underground pipeline broke Tuesday and leaked into a culvert leading to the ocean. Houston-based Plains All American Pipeline said an estimated 21,000 gallons of oil were released before the pipeline was shut down Tuesday. Photos by Jonathan Alcorn/Greenpeace.
