“I actually love diving at night; you see a lot of fish then that you don’t see in the daytime.”

And there’s no question that it is a factor, but it’s preceded by the loss of resilience and degradation.

Nearly all of the major kinds of life, divisions of life, phyla of animals, occur in the sea. Only about half of them can make it to land or freshwater.

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.

There is a terribly terrestrial mindset about what we need to do to take care of the planet.

They have a lateral line down their whole body that senses motion, but maybe it does more than that.

For heaven’s sake, when you see the enemy attacking, you pick up the pitchfork, and you enlist everybody you see.

The Arctic is an ocean. The southern pole is a continent surrounded by ocean. The North Pole is an ocean, or northern waters. It’s an ocean surrounded by land, basically.

Everyone has power. But it doesn’t help if you don’t use it.

Like a shipwreck or a jetty, almost anything that forms a structure in the ocean, whether it is natural or artificial over time, collects life.

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

The Arctic is a place that historically, during all preceding human history, has largely been an icy realm with an impact on ocean currents.

I have come up at the end of a dive, and the boat was not where I left it. I had to take care of a buddy who did panic. But I was confident the boat would come back.

Humans are the only creatures with the ability to dive deep in the sea, fly high in the sky, send instant messages around the globe, reflect on the past, assess the present and imagine the future.

If somebody dumps something noxious in my back yard, the dumper is the last one I would call on to repair the damage.

We have become frighteningly effective at altering nature.

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

To take what there is in life and use it, without waiting forever in vain for the preconceived, to dig deep into the actual and get something out of that; this, doubtless, is the right way to live.

There’s a reason why there’s a problem with bodies, and it’s because you never actually get to see any normal versions of them.

We say that the sun is behind the clouds, but actually it is not the sun but the city from which we view it that is behind the clouds. If we realized that the sun is never behind the clouds we might have a different attitude toward the whole thing.

There are moments when the inner life actually ‘pays,’ when years of self-scrutiny, conducted for no ulterior motive, are suddenly of practical use.

We actually did perform it in front of all those thousands of people. And just beforehand, we had a little dress rehearsal, and there were all these famous wrestlers going around and watching as well. Terrifying.

When I was in college, I actually had them change the starting lineup to say ‘from Robbins, Illinois’ instead of ‘Chicago, Illinois.’

Sometimes people carry to such perfection the mask they have assumed that in due course they actually become the person they seem.

That, for me, actually is the most important thing about doing a period film is trying to make these people as lovable as they are back then.
