Oil is starting to wash ashore in the U.S. state of Louisiana, threatening the coastline's delicate wildlife. President Obama's sent cabinet officials to deal with the crisis and pledged to use 'every single available resource' to respond. The spill comes from a BP oil rig in the Gulf of Mexico which sank after an explosion, killing 11 workers. Coast guards say up to five-thousand barrels of oil a day are spewing into the sea.
