Photosynthetic organisms in the sea yield most of the oxygen in the atmosphere, take up and store vast amounts of carbon dioxide, shape planetary chemistry, and hold the planet steady.

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

In terms of personal choices, let's all think more carefully about where we get our protein from.

This much is certain: We have the power to damage the sea, but no sure way to heal the harm.

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.

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.

You don't have to touch the ocean for the ocean to touch you
