You should know what is taken out of the ecosystem in order to give you a moment's sustenance.

If you think the ocean isn't important, imagine Earth without it. Mars comes to mind. No ocean, no life support system.

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.

We've got to somehow stabilize our connection to nature so that in 50 years from now, 500 years, 5,000 years from now there will still be a wild system and respect for what it takes to sustain us.

Even our rules and regulations, our laws, our policies, favor the destructive nature of taking too much from the ocean and using techniques that are horribly destructive. We know they don't work. We know it's not sustainable.

Historically, girls have not been encouraged to be scientists, to be explorers, and there's a social kind of constraint, of course. Having the responsibility, a disproportionate part of the responsibility, for caring for families, caring for children.
