Five years after BP's (BP) Deepwater Horizon rig exploded, affected areas are showing signs of strength, but some scientists remain skeptical over just how much damage the oil spill caused. '[The spill] was nowhere near as large as the news [media] made it to be, but in certain targeted areas, there was an impact,' said Curtis Richardson, professor & director of the Duke University Wetlands Center. 'The vast majority of impact would have been in the deeper water and also on the bottom of the Gulf itself, so this oil spill, although massive, was so far out that only a portion of the marshes were hit.' Plus, attorney Kenneth Feinberg, who oversaw victim compensation for the spill, and former U.S. Coast Guard Admiral Thad Allen, who was National Incident Commander during the time of the spill, weigh in on the 2010 tragedy.
