Authorities around the Gulf of Mexico are in a race against time. They are trying to control an oil spill that’s heading toward the Louisiana Shore. Yesterday, it was about 23 miles off the coast of Louisiana, could reach land by Friday. If that happens, officials say it could create an ecological disaster. This is all from the Deepwater Horizon. That’s the oil rig that sank in the Gulf last week. The company that owns the rig is trying to stop the leak underwater. Meantime, authorities on shore are trying to block the oil from getting to sensitive areas.
