We do not inherit the earth from our ancestors, we borrow it from our children.

The environment is where we all meet; where we all have a mutual interest; it is the one thing all of us share.

What we are doing to the forests of the world is but a mirror reflection of what we are doing to ourselves and to one another.

Environment is no one's property to destroy; it's everyone's responsibility to protect.

The greatest threat to our planet is the belief that someone else will save it.

Our environmental problems originate in the hubris of imagining ourselves as the central nervous system or the brain of nature. We're not the brain, we are a cancer on nature.

The environment is not a luxury, it is a necessity for human survival.

We need to reconnect with the natural world, not just because it's good for the environment, but because it's good for us.

The environment and the economy are really both two sides of the same coin. If we cannot sustain the environment, we cannot sustain ourselves.
