Nothing says summer like a trip to the beach. And of course fish and seafood are great eating all year round. Before you head to the coast or fire up the barbie, go check out the outstanding website Oceans Alive http://www.oceansalive.org produced by Environmental Defense (formerly known as the Evironmental Defense Fund).
You’ll find an amazing array of information there on coastal ecology, eco-friendly fish buying tips, and yummy recipes. See especially website sections on “Best and Worst Seafood Choices” and “Consumption Advisories: Fish to Avoid”. The “Explore the Depths” section offers a great set of information resources about the current state of health of the oceans.
