For every minute, the future is becoming the past.

We are not talking about esthetics. We are talking about life: survival of Man. We must train young people to get another vision of Nature. We call it 'wilderness,' and we think it is progress to get further and further away from it. How crazy! Where would we have been if Nature had not built us up?

This world has seen a great many civilizations. And many of them have survived for longer periods than ours up to the present. They were all as sure as we are today of having founded the first eternal civilization. We today differ from them in having our western civilization spread to embrace the entire planet, leaving no room on any continent for any other culture to take over if we fail.

One learns more from listening than speaking.And both the wind and the people who continue to live close to nature still have much to tell us which we cannot hear within university walls.

But if we begin thinking about the world being over 100 million years old, then it's absolutely by chance that you and I are sitting here alive today, while all the others are dead or have never been born.

It is progress when a centuries-old oak is cut down to give space for a road sign.

It is progress when weapons are improved to kill more people at a longer range.
