After BP oil spill, Louisiana tribe's way of life quickly disappearing

Five years after the BP Deepwater Horizon oil rig exploded, killing 11 employees and dumping as much as 200 million gallons of crude oil into the Gulf of Mexico, the region and its inhabitants are still scarred. Gulf residents say the impact is already devastating, but scientists fear they haven’t uncovered many of the long-term effects. Meanwhile, the clock is ticking for some communities, like the Pointe-au-Chein tribe in southern Louisiana, who are already watching their land and livelihood disappear.
