The Earth is a unique system in the universe, the only planet we know of that's hospitable for humankind.

All through college, I had frequently been the only girl in a science class - which wasn't such a bad deal.

When I first ventured into the Gulf of Mexico in the 1950s, the sea appeared to be a blue infinity too large, too wild to be harmed by anything that people could do.

Look at a child and realize that their future is in your hands. It's not just those who will be here fifty years from now. The decisions we make in the next ten years will shape the next 10,000 years.

Throughout all of human history we have consumed the natural world. All creatures do. Birds do. Fish do. Earthworms do. We consume the natural world as a source of our survival. But no creature has ever consumed at the scale that humans have, and now there are seven billion of us. I think the good news is that a large percentage of those seven billion minds can work to make better decisions.

Why does evolution matter? There is so much about the evolution of life, the development of life on Earth that should rivet the attention of everyone to understand where we've come from and where we might be going. We need to understand the world around us if we are to succeed as a species on the planet.

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