It's an appreciation for life generally, every bit of life, the smallest creature that lives in the intestines of termites that make termite life possible - to the leaves that turn out oxygen and grab carbon dioxide and with water make simple sugars that feed much of the world. I mean, these are everyday miracles.

If you make the choice to just go with the flow, that is a choice to make a difference in a negative way.

The ocean is dying, and we have no place to escape to if this experiment doesn't go in our favor.

The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents. That, in turn, influences the temperature of the planet. The Arctic is now vulnerable because of the excess carbon dioxide in the atmosphere, with a rate of melting that is stunning.

People ask: Why should I care about the ocean? Because the ocean is the cornerstone of earth's life support system, it shapes climate and weather. It holds most of life on earth. 97% of earth's water is there. It's the blue heart of the planet - we should take care of our heart. It's what makes life possible for us. We still have a really good chance to make things better than they are. They won't get better unless we take the action and inspire others to do the same thing. No one is without power. Everybody has the capacity to do something.

There is a terribly terrestrial mindset about what we need to do to take care of the planet-as if the ocean somehow doesn't matter or is so big, so vast that it can take care of itself, or that there is nothing that we could possibly do that we could harm the ocean...We are learning otherwise.

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.
