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.

I am not in any hurry to grow up.

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

What we put into the atmosphere in terms of burning fuel is unprecedented.

It doesn't matter where on Earth you live, everyone is utterly dependent on the existence of that lovely, living saltwater soup. There's plenty of water in the universe without life, but nowhere is there life without water.

The oceans deserve our respect and care, but you have to know something before you can care about it.

Many of us ask what can I, as one person, do, but history shows us that everything good and bad starts because somebody does something or does not do something.
