Just now, the President took action to protect a place called Bristol Bay, Alaska. Here's why that matters:

It places a national treasure -- and one of the nation's most productive fisheries -- off limits for oil and gas leasing. Alaskans have been fighting to preserve Bristol Bay for decades. Today, we got it done.

Bristol Bay helps to produce 40 percent of America's wild-caught seafood each year. It supports $2 billion every year in commercial fishing, and supports good jobs in sport-fishing and tourism.

These waters are beautiful and valuable, and today's action will ensure that future generations will be able to enjoy their bounty.
