Lady Bird Johnson
5.

I think the environment should be put in the category of our national security. Defense of our resources is just as important as defense abroad. Otherwise what is there to defend?
Robert Redford

We came all this way to explore the Moon, and the most important thing is that we discovered the Earth.
William Anders

Chief Seattle

All of us have a God in us, and that God is the spirit that unites all life, everything that is on this planet. It must be this voice that is telling me to do something, and I am sure it's the same voice that is speaking to everybody on this planet - at least everybody who seems to be concerned about the fate of the world, the fate of this planet.
Wangari Maathai
22.
The study of history is a powerful antidote to contemporary arrogance. It is humbling to discover how many of our glib assumptions, which seem to us novel and plausible, have been tested before, not once but many times and in innumerable guises; and discovered to be, at great human cost, wholly false.
Paul Johnson
23.
There is a great need for the introduction of new values in our society, where bigger is not necessarily better, where slower can be faster, and where less can be more.
Gaylord Nelson

Juvenal

My world, my Earth is a ruin. A planet spoiled by the human species. We multiplied and fought and gobbled until there was nothing left, and then we died. We controlled neither appetite nor violence; we did not adapt. We destroyed ourselves. But we destroyed the world first.
Ursula K. Le Guin
30.
A Zen master, when asked where he would go after he died, replied, 'To Hell, for that's where help is needed most.'
Philip Kapleau

The future will be green, or not at all. This truth lies at the heart of humankind's most pressing challenge: to learn to live in harmony with the Earth on a genuinely sustainable basis.
Jonathon Porritt

I love not man the less, but Nature more.
Lord Byron

Till now man has been up against Nature; from now on he will be up against his own nature.
Dennis Gabor
36.
Our primeval Mother Earth is an organism that no science in the world can rationalize. Everything on her that crawls and flies is dependent upon Her and all must hopelessly perish if that Earth dies that feeds us.
Viktor Schauberger

Rachel Carson
47.
Contrary to the ecologists, nature does not stand still and does not maintain the kind of equilibrium that guarantees the survival of any particular species - least of all the survival of her greatest and most fragile product: man.
Ayn Rand
