Johann von Goethe on Earth
The world is so empty if one thinks only of mountains, rivers and cities; but to know someone here and there who thinks and feels with us, and though distant, is close to us in spirit - this makes the earth for us an inhabited garden.
Wendell Berry on Earth
To cherish what remains of the Earth and to foster its renewal is our only legitimate hope of survival.
Marshall McLuhan on Earth
There are no passengers on spaceship earth. We are all crew.
