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.

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.

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.

I am drawn to the wild not because it is wild but because it is sensible, logical, ordered, stable, resilient. Wild nature is everything we're struggling to regain.

Many people believe the whole catastrophe is the oil we spill, but that gets diluted and eventually disarmed over time. In fact, the oil we don't spill, the oil we collect, refine and use, produces CO2 and other gases that don't get diluted.

But one doesn't wait for a revolution. One becomes it.

The compass of compassion asks not what is good for me? but what is good? Not what is best for me but what is best. Not what is right for me but what is right. Not how much can we take? but How much ought we leave? and how much might we give? Not what is easy but what is worthy. Not what is practical but what is moral.

We put the murderer in charge of the crime scene.

Whether on'e special emphasis is global warming or child welfare, the cause is the same cause. And justice comes from the same place being human comes from: compassion.

Economists don't seem to have noticed that the economy sits entirely within the ecology.

Fishing provides time to think, and reason not to. If you have the virtue of patience, an hour or two of casting alone is plenty of time to review all you’ve learned about the grand themes of life.

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.

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.
