To me a lush carpet of pine needles or spongy grass is more welcome than the most luxurious Persian rug.

Helen Keller

All sensible people are selfish, and nature is tugging at every contract to make the terms of it fair.

Ralph Waldo Emerson

When Nature has work to be done, she creates a genius to do it.

Ralph Waldo Emerson

You can't just let nature run wild.

Wally Hickel

Climb the mountains and get their good tidings. Nature's peace will flow into you as sunshine flows into trees. The winds will blow their own freshness into you, and the storms their energy, while cares will drop off like autumn leaves.

John Muir

You can't be suspicious of a tree, or accuse a bird or a squirrel of subversion or challenge the ideology of a violet.

Hal Borland

There is a pleasure in the pathless woods,
There is a rapture on the lonely shore,
There is society, where none intrudes,
By the deep sea, and music in its roar:
I love not man the less, but Nature more.

George Gordon

Never does nature say one thing and wisdom another.

Juvenal's Satires

The human spirit needs places where nature has not been rearranged by the hand of man.

After all, I don't see why I am always asking for private, individual, selfish miracles when every year there are miracles like white dogwood.

Anne Morrow Lindbergh

In wilderness I sense the miracle of life, and behind it our scientific accomplishments fade to trivia.

Charles A. Lindbergh

The poetry of the earth is never dead.

John Keats
