Many of us ask what can I, as one person, do, but history shows us that everything good and bad starts because somebody does something or does not do something.

Never again will we have this good a chance as we now have to find an enduring place for ourselves within the natural systems that keep us alive. It's a sweet spot in history. That's why this is such a critical time.

Places change over time with or without oil spills, but humans are responsible for the Deepwater Horizon gusher - and humans, as well as the corals, fish and other creatures, are suffering the consequences.

Far and away, the greatest threat to the ocean, and thus to ourselves, is ignorance. But we can do something about that.

I want to get out in the water. I want to see fish, real fish, not fish in a laboratory.

Eating wildlife is probably not the smartest thing that we can do in terms of maintaining the integrity of natural systems.

Every time I slip into the ocean, it's like going home.
