We’re fascinated with outer space, but there’s a place on earth that’s just as alien — and just as mysterious. It’s the bottom of the ocean, and Sylvia Earle has walked there:
"[I walked] on the bottom, two and a half hours, and I later spoke with an astronaut friend, Buzz Aldrin, and he said, ‘Well, that’s about as long as we had to walk on the moon, two and a half hours.’ But what they did not have on the moon, Buzz Aldrin and Neil Armstrong and those who came later, they didn’t have just this avalanche of life, this great diversity all around. Everywhere you looked, there were little fish with lights down the side. Of course, the corals themselves are alive. There were little burrows of creatures that were dwelling in the sediments on the sea floor. The water itself is like minestrone, except all the little bits are alive."
And that life of the ocean sustains all life on earth. Sylvia Earle takes us there with singular urgency and passion.
