We have been far too aggressive about extracting ocean wildlife, not appreciating that there are limits and even points of no return.

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.

Great attention gets paid to rainforests because of the diversity of life there. Diversity in the oceans is even greater.

We want to think of ourselves as truly special creatures that are unique in the universe and, well, we are. And we have that capacity to wonder, to question, and to see ourselves in the context of all of life that has preceded the present time, and all that will go off far into the future, one way or another.

I suggest to everyone: Look in the mirror. Ask yourself: Who are you? What are your talents? Use them, and do what you love.
