“My country is the world, and my religion is to do good.”
– Thomas Paine, in The Rights of Man

“My patriotism is not an exclusive thing. It is all-embracing and I should reject that patriotism which sought to mount upon the distress or the exploitation of other nationalities. The conception of my patriotism is nothing if it is not always, in every case without exception, consistent with the broadest good of humanity at large. Not only that, but my religion and my patriotism derived from my religion embrace all life. I want to realize brotherhood or identity not merely with the beings called human, but I want to realize identity with all life, even with such things as crawl on earth…”
– Mahatma Gandhi

Our loyalties are to the species—all the species—and the planet itself. WE speak for earth. Our obligation to survive [and thrive] is owed not just to ourselves but also to that Cosmos, ancient and vast, from which we have sprung.
– Carl Sagan

“We travel together, passengers on a little spaceship, dependent upon its vulnerable reserves of air and soil, all committed for our safety to its security and peace, preserved from annihilation only by the care, the work, and I will say the love we give our fragile craft. We cannot maintain it half-fortunate, half-miserable, and half-free in the liberation of resources undreamed of until this day. No craft, no crew can travel safely with such vast contradictions. On their resolution depends the survival of us all.”
– Adlai Stevenson

“Die gefährlichste Weltanschauung ist die Weltanschauung derer, die die Welt nie angeschaut haben. (The most dangerous worldview is the worldview of those who have not viewed the world)”
– Alexander von Humboldt

“We pledge allegiance to the earth and all the life which it supports. One Planet, in our care, irreplaceable, with sustenance and respect for all.”
– Anonymous

“The more clearly we can focus our attention on the wonders and realities of the universe, the less taste we shall have for destruction.”
– Rachel Carson

“Mankind is a single body and each nation a part of that body. We must never say “What does it matter to me if some part of the world is ailing?” If there is such an illness, we must concern ourselves with it as though we were having that illness.”
– Mustafa Kemal Ataturk

“While our flags are waving and patriotism is a constant subject in public discourse, those of us who care deeply about the environment can add our voices as true patriots — not only supporting our human community but also the earth on which our nation stands.”
– Richard Nelson

“To secure our common future, we need a new international vision based on cooperation and a new environmental ethic based on the realization that the issues with which we wrestle are globally interconnected. This is not only a moral ethic but also a practical one – the only way we can pursue our own self interests on a small and closely knit planet.”
– Gro Harlem Brundtland

“Preserving the resources we share is crucial not only for the quality of our individual environments and health, but also to maintain stability and peace within nations and among them.”
– William J. Clinton

Well I’m a child of many worlds
and if I had to choose just one,
I’d say my home is the planet
that circles around the sun.
It’s like a ship and we’re on it for a ride
at the end of the night we’re all on the same side.
We may be different in the ways we think
but if we don’t hang together the ship is gonna sink.
– Erika Luckett, “Kindness,” from Amaze Me: Songs in the Key of Peace.

“My loyalties will not be bound by national borders, or confined in time by one nation’s history, or limited in the spiritual dimension by one language or culture. I pledge my allegiance to the damned human race, and my everlasting love to the green hills of Earth, and my intimations of glory to the singing stars, to the very end of space and time.”  
– Edward Abbey

“Every astronaut,cosmonaut, and taikonaut comes down and reminds us: we are all citizens of one world,one planet. It’s up to us to preserve it. Clean water, renewably produced electricity, and access to global information – for everyone on  Earth. Let’s Go!”
– Bill Nye

“We are a part of one earth, one pale-blue dot that’s in the middle of an endless sea of blackness. What we’re saying is that we must act as such, we must act as if we are one people, one planet, and one globally interconnected nation.”
– Jerome Foster, at Fire Drill Friday, October 11, 2019  – Quoted in: — What Can I Do?: My Path from Climate Despair to Action by Jane Fonda

“The Earth itself, with its immensely deep history, is a communal heritage and universal mentor that may help us find a set of shared values. Studying its past may cause us to reconceive ourselves as fellow citizens of a profoundly mysterious planet that we urgently need to know better.”
– Marcia Bjornerud, from Timefulness: How Thinking Like a Geologist Can Help Save the World

“We must live together as brothers or perish together as fools.”
– Dr. Martin Luther King, Jr.

“I mean no disrespect for the white-haired veterans in my town, who stand with hand on heart as the flag goes by, whose eyes fill with tears as they recite the Pledge with raspy voices. I love my country too, and its hopes for freedom and justice. But the boundaries of what I honor are bigger than the republic. Let us pledge reciprocity with the living world… If what we want for our people is patriotism, then let us inspire true love of country by invoking the land herself. If what we aspire to is justice for all, then let it be justice for all of Creation.” 
– Robin Kimmerer

“Welcome to the planet Earth—a place of blue nitrogen skies, oceans of liquid water, cool forests and soft meadows, a world positively rippling with life. In the cosmic perspective it is, as I have said, poignantly beautiful and rare; but it is also, for the moment, unique. In all our journeying through space and time, it is, so far, the only world on which we know with certainty that the matter of the Cosmos has become alive and aware.”
– Carl Sagan

“Throughout history, people have spoken of the earth as our mother and the sun as our father, perhaps reflecting prevailing views of traditional sex roles. In an atomic sense, however, it would be more accurate to think of the earth and the sun as our siblings, because they both formed from the same star debris as the elements of life within us.”
– Curt Stager
