It is fashionable nowadays to talk about the endless riches of the sea. The ocean is regarded as a sort of bargain basement, but I don't agree with that estimate. People don't realize that water in the liquid state is very rare in the universe. Away from earth it is usually a gas. This moisture is a blessed treasure, and it is our basic duty, if we don't want to commit suicide, to preserve it.

The reason I love the sea I cannot explain - it's physical. When you dive you begin to feel like an angel. It's a liberation of your weight.

We must plant the sea and herd its animals using the sea as farmers instead of hunters. That is what civilization is all about - farming replacing hunting.

We are living in an interminable succession of absurdities imposed by the myopic logic of short-term thinking.

Man has only to sink beneath the surface and he is free.

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.

No aquarium, no tank in a marine land, however spacious it may be, can begin to duplicate the conditions of the sea. And no dolphin who inhabits one of those aquariums or one of those marine lands can be considered normal.
