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.

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.

From the happy-go-lucky days of oil exploration and drilling, when a lot of easy sources were being found and easily managed, we're gotten ourselves into this sort of apocalyptic time. We're willing to destroy almost everything, risk almost anything, and go ahead with techniques for which we have no way of responding to the known problems.

Several groups have information evaluating seafood sustainability. I wrote the first such guide, and seafood pocket-guides and detailed evaluations of different seafoods are available for download from the group I founded, Blue Ocean Institute.

Try to cut down drastically on plastic. Recycle. Use less energy and more renewable energy. We can all live better by doing better for ourselves and the sea!

To save the seas, we can eat sustainably and be conscious of the seafood we eat.
