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

The end of commercial fishing is predicted long before the middle of the 21st century.

I'm not against extracting a modest amount of wildlife out of the ocean for human consumption, but I am really concerned about the large-scale industrial fishing that engages in destructive practices like trawling and longlining.

Our job is to keep what is working intact and not destroy what we have got.

Any astronaut can tell you you've got to do everything you can to learn about your life support system and then do everything you can to take care of it.

We still have the illusion that the ocean will recover. That even if we do have to lose sharks, people don't understand why this matters. The evidence is in front of us, and we fail to take it in and say, "Now I get it. Now I understand."

Rather than be afraid of evolution and try to stifle inquiry, people should revel in the joys of knowing and find a serenity and a joy in being a part the rest of life on Earth. Not apart from it, but a part of it.
