To leave the world better than you found it, sometimes you have to pick up other people’s trash.

One of the things I enjoy is the challenge of Mother Nature.

We have forgotten how to be good guests, how to walk lightly on the earth as its other creatures do.

Mother Nature comes up against reality, and the reality is that the system doesn't work.

Preserve and cherish the pale blue dot, it’s the only home we’ve ever known.

That's the thing about Mother Nature, she really doesn't care what economic bracket you're in.

Rain is grace; rain is the sky descending to the earth; without rain, there would be no life.

Mother Nature made me the way I am, and I should be happy.

He that plants trees love others besides himself.

Those who find beauty in all of nature will find themselves at one with the secrets of life itself.

Sunset is still my favorite color, and rainbow is second.

There are no passengers on Spaceship Earth. We are all crew.

Time spent amongst trees is never wasted time.

Nature is pleased with simplicity. And nature is no dummy.

Land really is the best art.

On Earth there is no heaven, but there are pieces of it.

There are always flowers for those who want to see them.

And forget not that the earth delights to feel your bare feet and the winds long to play with your hair.

The earth belongs to the living, not to the dead.
