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

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.

A common denominator in every single nuclear accident - a nuclear plant or on a nuclear submarine - is that before the specialists even know what has happened, they rush to the media saying, 'There's no danger to the public.' They do this before they themselves know what has happened because they are terrified that the public might react violently, either by panic or by revolt.

It's terrible to have to say this. World population must be stabilized and to do that we must eliminate 350,000 people per day. This is so horrible to contemplate that we shouldn't even say it. But the general situation in which we are involved is lamentable.

A lot of people attack the sea, I make love to it.

We forget that the water cycle and the life cycle are one.

We have to prepare for what life could become in 40 years. We need to outline what is possible and what is impossible with the non-renewable resources of the Earth. What role will technological improvement play? Taking all this into account, what kind of life can we produce in the best way for 10 billion people? That's a problem that needs to be solved.
