The conversation: One year since the BP oil spill, but still a long way from recovery

It's been one year since BP's Deepwater Horizon drilling rig exploded. Eleven workers were killed. Some of those who make a living off the sea and the land went into financial ruin. And it devastated the environment and the delicate ecosystems of the Gulf of Mexico. Today's theme: Just because you can't see the oil doesn't mean it isn't there; and just because the media have shifted their attention to other critical issues doesn't mean the disaster has vanished into thin air.
