San Francisco International Airport

Cleared for take-off.

Pilots are drawn to flying because it's a perfect combination of science, romance and adventure.

Charles Lindbergh

My soul is in the sky.

William Shakespeare

When we contemplate the whole globe as one great dewdrop, striped and dotted with continents and islands, flying through space with other stars all singing and shining together as one, the whole universe appears as an infinite storm of beauty.

It's only when you're flying above it that you realize how incredible the Earth really is.

Philippe Perrin

Butte, Montana

Treat the earth well: it was not given to you by your parents, it was loaned to you by your children. We do not inherit the Earth from our Ancestors, we borrow it from our Children.

Crazy Horse

Sheridan, Powder River Country, Wyoming

The earth is what we all have in common.

Wendell Berry

What you do makes a difference, and you have to decide what kind of difference you want to make.

Jane Goodall

Gillette, Powder River Country, Wyoming

Heaven on Earth is a choice you must make, not a place you must find.

Wayne Dyer

Buffalo Gap National Grassland, Buffalo Gap, South Dakota

The earth does not belong to man, man belongs to the earth. All things are connected like the blood that unites us all. Man did not weave the web of life, he is merely a strand in it. Whatever he does to the web, he does to himself.

Chief Seattle

There are no passengers on spaceship earth. We are all crew.

Marshall McLuhan

Merriman, Nebraska

The earth is our mother. Whatever befalls the earth befalls the sons of earth. If men spit upon the ground, they spit upon themselves.

Human use, population, and technology have reached that certain stage where mother Earth no longer accepts our presence with silence.

Dalai Lama

Every moment and every event of every man's life on earth plants something in his soul.

Thomas Merton

Above all we must realize that each of us makes a difference with our life. Each of us impacts the world around us every single day. We have a choice to use the gift of our life to make the world a better place - or not to bother.

Jane Goodall

Tarkio, Missouri

Life comes from the earth and life returns to the earth.

Zhuangzi

People usually consider walking on water or in thin air a miracle. But I think the real miracle is not to walk either on water or in thin air, but to walk on earth. Every day we are engaged in a miracle which we don't even recognize: a blue sky, white clouds, green leaves, the black, curious eyes of a child -- our own two eyes. All is a miracle.

Nhat Hanh

Rushville, Missouri

The air up there in the clouds is very pure and fine, bracing and delicious. And why shouldn't it be?--it is the same the angels breathe.

Mark Twain

When one tugs at a single thing in nature, he finds it attached to the rest of the world.

John Muir

We have nowhere else to go. . . this is all we have.

Margaret Mead

Atchison, Kansas

As the plane descended from 35,000 ft, and we began the approach to Kansas City's Airport, a silhouette of the plane surrounded by a rainbow halo appeared in the clouds.

This natural phenomenon lasted for slightly more than a minute.

This natural phenomenon is called a Brocken Spectre

For those who have experienced the joy of being alone with nature there is really little need for me to say much more; for those who have not, no words of mine can ever describe the powerful, almost mystical knowledge of beauty and eternity that come, suddenly, and all unexpected.

Jane Goodall

Camden Point, Missouri

Kansas City, Santa Fe Trail, Kansas

Touch the earth, love the earth, honour the earth, her plains, her valleys, her hills, and her seas; rest your spirit in her solitary places.

Henry Beston

You must teach your children that the ground beneath their feet is the ashes of your grandfathers. So that they will respect the land, tell your children that the earth is rich with the lives of our kin. Teach your children what we have taught our children, that the earth is our mother. Whatever befalls the earth befalls the sons of the earth. If men spit upon the ground, they spit upon themselves.

Chief Seattle

Suburbia is where the developer bulldozes out the trees, then names the streets after them.

Sooner or later, we will have to recognise that the Earth has rights, too, to live without pollution. What mankind must know is that human beings cannot live without Mother Earth, but the planet can live without humans.

Evo Morales

It's only when we truly know and understand that we have a limited time on earth - and that we have no way of knowing when our time is up, we will then begin to live each day to the fullest, as if it was the only one we had.

Elisabeth Kubler-Ross

We shall continue to have a worsening ecologic crisis until we reject the Christian axiom that nature has no reason for existence save to serve man.

Lynn Townsend White Jr.

Heavier-than-air flying machines are impossible.

Lord Kelvin

Tonto National Forest, Payson, Arizona

Look deep into nature, and then you will understand everything better.

Albert Einstein

Here we are, arguably the most intelligent being that's ever walked planet Earth, with this extraordinary brain ... and yet we're destroying the only home we have.

Jane Goodall

Tonto National Forest, Rio Verde, Arizona

It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.

Neil Armstrong

Man must rise above the Earth - to the top of the atmosphere and beyond - for only thus will he fully understand the world in which he lives.

Socrates
