If you ask the fish whether they'd rather have an oil spill or a season of fishing, I wouldn't be surprised if they'd vote for another blowout.

The ocean is not just blank blue space but rather the habitat for amazing wildlife, and we have to take care how we use it. If we want to keep having the goods and services it provides, we have to treat it more carefully in terms of fishing and dumping.

The creatures of the sea hold special mystery, and they are among the most exciting, graceful, and beautiful on Earth. Just consider the living riot of a coral reef, the beauty of an albatross, the awesome power of a giant turtle, the grace of a dolphin. Now multiply that by the millions of creatures in the sea. Wow!

If you're overfishing at the top of the food chain, and acidifying the ocean at the bottom, you're creating a squeeze that could conceivably collapse the whole system.

For proponents of ecosystem-based management,the good news is that another new book, Ecosystem-based Management for the Oceans, conveys the topic at its state-of-the-art level of development...both Marine Ecosystems and Global Change and Ecosystem-based Management for the Oceans are valuable troves that could profitably be mined, and any academic bookshelf would wear them well.

We are blessed with a magnificent and miraculous world ocean on this planet. But we are also stressing it in ways that we are not even close to bringing under control.

Maybe we’ll live to see sharks recover. Right now, that seems as improbable as seeing all these falcons. Hope is the ability to see how things could be better. The world of human affairs has long been a shadowy place, but always backlit by the light of hope. Each person can add hope to the world. A resigned person subtracts hope. The more people strive, the more change becomes likely.
