I personally have stopped eating seafood.

By the end of the 20th century, up to 90 percent of the sharks, tuna, swordfish, marlins, groupers, turtles, whales, and many other large creatures that prospered in the Gulf for millions of years had been depleted by overfishing.

Health to the ocean means health for us.

It's mainly the high-end luxury market now that drives much of the fishing in the sea. It's not feeding the starving millions. It's feeding a luxury market.

Knowledge is the key to making a difference.

I actually love diving at night; you see a lot of fish then that you don't see in the daytime.

When I write a scientific treatise, I might reach 100 people. When the 'National Geographic' covers a project, it communicates about plants and fish and underwater technology to more than 10 million people.
