A world is sooner destroyed than made.

You may drive out nature with a pitchfork, yet she’ll be constantly running back.

Are we not ourselves nature, nature without end?

It seems to me that we all look at nature too much and live with her too little.

The earth is beautiful and bright and kindly, but that is not all. The earth is also terrible and dark and cruel.

Man’s great mission is not to conquer nature by main force but to cooperate with her intelligently but lovingly for his own purposes.

Those who cross the seas change their climate but not their character.

When nature is overriden, she takes her revenge.

The oldest voice in the world is the wind.

We seek with our human hands to create a second nature in the natural world.

Before the earth could become an industrial garbage can, it had first to become a research laboratory.

In tampering with the earth, we tamper with a mystery.

It is hard when nature does not respect your intentions, and she never does exactly respect them.
