The end of commercial fishing is predicted long before the middle of the 21st century.

We have found ways to capture, kill and market ocean wildlife on an unprecedented scale. It's an absolute catastrophe.

No water, no life. No blue, no green.

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.

When I arrived on the planet, there were only two billion. Wildlife was more abundant, we were less so; now the situation is reversed.

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

Ocean acidification - the excess carbon dioxide in the atmosphere that is turning the oceans increasingly acid - is a slow but accelerating impact with consequences that will greatly overshadow all the oil spills put together. The warming trend that is CO2-related will overshadow all the oil spills that have ever occurred put together.
