I see a world in the future in which we understand that all life is related to us and we treat that life with great humility and respect.

Unless we are willing to encourage our children to reconnect with and appreciate the natural world, we can't expect them to help protect and care for it.

If all humans disappeared today ,the earth would start improving tomorrow.If all the ants disappeared today ,the earth would start dying tomorrow.

Change is never easy, and it often creates discord, but when people come together for the good of humanity and the Earth, we can accomplish great things.

If one day I look out from my cabin's porch and see a row of windmills spinning in the distance, I won't curse them. I will praise them. It will mean we are finally getting somewhere.

If we pollute the air, water and soil that keep us alive and well, and destroy the biodiversity that allows natural systems to function, no amount of money will save us.

In nature there is no such thing as waste. In nature nothing is wasted; everything is recycled.

How you imagine the world determines how you live in it.

A lack of empathy is the greatest crime of all.

There's nothing more dangerous than someone who wants to make the world a better place.

Anyone's life truly lived consists of work, sunshine, exercise, soap, plenty of fresh air, and a happy contented spirit.

I try not to get impressed. I just try to look at what I see.

Fang: "Have you guys been playing in the toxic waste again? Been bitten by a radioactive spider? Struck by lightning? Drink a super-soldier serum?"

I'll just say that I made my own explorations of tone by listening to a tone for a long time until I began to understand what my sensations were, what my mind was doing with tone.

Religion and liberty are inseparable. Religion is voluntary, and cannot and ought not to be forced.

When people say I can't or I musn't, I always say I can and I will.

What likelihood is there of corrupting a man who has no ambition.

Using a metaphor in front of a man as unimaginative as Ridcully was like a red flag to a bu... was like putting something very annoying in front of someone who was annoyed by it.
