National Geographic photographer Brian Skerry makes a powerful case for protection of the world’s marine environments during a recent TED talk.

From TED:

Photographer Brian Skerry shoots life above and below the waves — as he puts it, both the horror and the magic of the ocean. Sharing amazing, intimate shots of undersea creatures, he shows how powerful images can help make change.

I think it goes without saying that Brian isn’t using a waterproof point and shoot camera.
