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.

There is this sweet spot in time when we have an opportunity to stop killing sharks and tunas and swordfish and other wildlife in the sea before it's too late.

Humans have always wondered the big questions, "Who am I? Where have I come from? Where am I going?" It's part of human nature. It's perhaps the underpinnings of religion.

Nothing has prepared sharks, squid, krill and other sea creatures for industrial-scale extraction that destroys entire ecosystems while targeting a few species.

The observations that have developed over the years have given us perspective about where we fit in. We are newcomers, really recent arrivals on a planet that is four and a half billion years old.

Some experts look at global warming, increased world temperature, as the critical tipping point that is causing a crash in coral reef health around the world. And there's no question that it is a factor, but it's preceded by the loss of resilience and degradation.
