Keep close to Nature’s heart… and break clear away, once in awhile, and climb a mountain or spend a week in the woods. Wash your spirit clean.

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.

We won’t have a society if we destroy the environment.

Environmental pollution is an incurable disease. It can only be prevented.

Sustainable development is the pathway to the future we want for all. It offers a framework to generate economic growth, achieve social justice, exercise environmental stewardship and strengthen governance.

The Earth does not belong to us: we belong to the Earth.

Thank God men cannot fly, and lay waste the sky as well as the earth.

If we’re destroying our trees and destroying our environment and hurting animals and hurting one another and all that stuff, there’s got to be a very powerful energy to fight that.

The environment is everything that isn’t me.

When we try to pick out anything by itself, we find it hitched to everything else in the universe.

Water and air, the two essential fluids on which all life depends, have become global garbage cans.
