If the sea is sick, we'll feel it. If it dies, we die. Our future and the state of the oceans are one.

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

What we once used as weapons of war, we now use as weapons against fish.

The oxygen cycle, the nitrogen cycle, the carbon cycle, the water cycle - all of these are linked to the existence of life in the sea.

I personally have stopped eating seafood.

The burning of fossil fuels has altered the amount of carbon dioxide in the atmosphere so rapidly and so abundantly that now, we are driving not just the warming trend, not just the sea level rise that is a consequence of the warming trend that is melting polar ice and alpine ice, but also [ocean acidification].

It's taken us a short time to change the nature of nature. In my lifetime, more change than during all preceding human history put together.
