Perhaps the time has come to formulate a moral code which would govern our relations with the great creatures of the sea as well as with those on dry land. That this will come to pass is my dear wish.

We are human beings, and we have faith, and we have hope

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.

What is a scientist after all? It is a curious man looking through a keyhole, the keyhole of nature, trying to know what's going on.

If human civilization is going to invade the waters of the earth, then let it be first of all to carry a message of respect.

The sea, once it casts its spell, holds one in its net of wonder forever.

We must alert and organise the world's people to pressure world leaders to take specific steps to solve the two root causes of our environmental crises - exploding population growth and wasteful consumption of irreplaceable resources. Overconsumption and overpopulation underlie every environmental problem we face today.
