Over 20,000 McDonalds worldwide will soon be selling only fish that has been verified by the Marine Stewardship Council as sustainable. 

The Fillet-O-Fish, and new Fish Bites will be sold in boxes that have the blue Eco-label from the Marine Stewardship Council. The sustainable fish is wild-caught Alaskan pollack. 

As one of the world's largest fish buyers, McDonalds sells hundreds of millions of the Fillet-O-Fish sandwiches each year.
