Fifty years ago, when I began exploring the ocean,

no one -- not Jacques Perrin, not Jacques Cousteau or Rachel Carson --

imagined that we could do anything to harm the ocean

by what we put into it or by what we took out of it.

It seemed, at that time, to be a sea of Eden,

but now we know, and now we are facing paradise lost.

my personal view of changes in the sea that affect all of us

and to consider why it matters that in 50 years we've lost --

more than 90 percent of the big fish in the sea,

why you should care that nearly half of the coral reefs have disappeared,

why a mysterious depletion of oxygen in large areas of the Pacific

should concern not only the creatures that are dying

I'm haunted by the thought of what Ray Anderson calls "tomorrow's child,"

asking why we didn't do something on our watch

to save sharks and bluefin tuna and squids and coral reefs and the living ocean

in ways that will restore the health and,

And I hope Jill Tarter's wish to engage Earthlings includes dolphins and whales

in this quest to find intelligent life elsewhere in the universe.

we will find evidence that there is intelligent life among humans on this planet.

It's when I first got to know fish swimming

in something other than lemon slices and butter.

You see a lot of fish then that you don't see in the daytime.

Diving day and night was really easy for me in 1970

when I led a team of aquanauts living underwater for weeks at a time

at the same time that astronauts were putting their footprints on the moon.

In 1979 I had a chance to put my footprints on the ocean floor

while using this personal submersible called Jim.

It was six miles off shore and 1,250 feet down.

Since then, I've used about 30 kinds of submarines

and I've started three companies and a nonprofit foundation called Deep Search

I led a five-year National Geographic expedition,

They're so simple to drive that even a scientist can do it.

really appreciate the importance of air, food, water, temperature,

all the things you need to stay alive in space or under the sea.

how he had to learn everything he could about his life support system

And then he pointed to this and he said: "Life support system."

We need to learn everything we can about it

and do everything we can to take care of it.

The poet Auden said, "Thousands have lived without love.

Ninety-seven percent of Earth's water is ocean.

I gave a talk not so long ago at the World Bank

and I said, "There it is! The World Bank!"

much faster than the natural systems can replenish them.

Tim Worth says the economy is a wholly-owned subsidiary of the environment.

Most of the oxygen in the atmosphere is generated by the sea.

Over time, most of the planet's organic carbon

stabilizes temperature, shapes Earth's chemistry.

and provides home for about 97 percent of life in the world,

that the Earth -- all of it: the oceans, the skies --
