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.

It's baffling why the issues relating to climate change - [which] have far more obvious and tangible and much more clear-cut evidence about the cause - have been slower for people to accept as a given.

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

We are not only warming the ocean and the planet as a whole, but we are also acidifying the ocean and changing its chemistry.

The best scientists and explorers have the attributes of kids! They ask question and have a sense of wonder. They have curiosity. 'Who, what, where, why, when, and how!' They never stop asking questions, and I never stop asking questions, just like a five year old.

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. I know this challenge from firsthand experience because I have three children and four grandsons.And some of the time I have spent as a scientist and as an explorer has meant choosing to not be with my children and grandchildren as much as I might otherwise have done had I not been a scientist, an explorer.

I am driven by what I know; that the world I love is in trouble.
