I hope that someday we will find evidence that there is intelligent life among humans on this planet.

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

The diversity of life on Earth, generally, is astonishing. But despite those large numbers, it's also important to recognize that every species, one way or another, is vulnerable to extinction. And in our time on Earth... our impact on the diversity of life has been profound.

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.

When some people look at a shrimp they think, "Hmm. Delicious." When I look at a shrimp I think, "You're a miracle, absolutely incredible. Your ancestors have gone back hundreds of millions of years." And to develop a thing as simple as a shrimp cocktail, you have to calculate the hundreds of millions of years that have preceded that moment where you're sitting there with your sauce and fork poised.

You should ask where your food is coming from.

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."
