A clean up worker holds a box of sea creatures killed by an oil slick along the coast of Refugio State Beach in Goleta, California, United States, May 21, 2015. As much as 2,500 barrels (105,000 gallons) of crude oil, according to latest estimates, gushed onto San Refugio State Beach and into the Pacific west of Santa Barbara when an underground pipeline running parallel to a coastal highway there inexplicably burst on Tuesday morning.
