I was watching Deadliest Catch on Tuesday (We'll miss you Phil) and during "After the Catch" they brought on fishermen from the gulf to talk about the impact of the oil spill. During that discussion, the captain of the Time Bandit pointed out that 25 years later, the fisheries affected by the Exxon Valdez have still not recovered.
This does not bode well for the future of the gulf. Here's a TED talk on the subject.
It's been my opinion that "the other shoe" hasn't dropped yet as far as the gulf spill goes. No one knows what the long term impact of this event will be, but judging from the aftermath of the much smaller Alaska spill I'd be surprised if there's much fishing left in the gulf, at all. Which begs the question, what are we going to eat, and how are those people going to make a living? Something to think about.
