The real cure for our environmental problems is to understand that our job is to salvage Mother Nature. We are facing a formidable enemy in this field. It is the hunters... and to convince them to leave their guns on the wall is going to be very difficult.

I said that the oceans were sick but they're not going to die. There is no death possible in the oceans - there will always be life - but they're getting sicker every year.

In order to save the planet it would be necessary to kill 350,000 people per day.

The awareness of our environment came progressively in all countries with different outlets.

I swam across the rocks and compared myself favorably with the sars. To swim fishlike, horizontally, was the logical method in a medium eight hundred times denser than air. To halt and hang attached to nothing, no lines or air pipe to the surface, was a dream. At night I had often had visions of flying by extending my arms as wings. Now I flew without wings. (Since that first aqualung flight, I have never had a dream of flying.)

Mankind has probably done more damage to the Earth in the 20th century than in all of previous human history.

If we were logical, the future would be bleak, indeed. But we are more than logical. We are human beings, and we have faith, and we have hope, and we can work.
