"Of all the animals, man is the only one that is cruel. He is the only one
that inflicts pain for the pleasure of doing it."
- Mark Twain
"I hold that the more helpless the creature, the more entitled it is to the
protection by man, from the cruelty of man."
- Ghandi
It's not hard, going to work every day in such a place, to be impressed with ourselves. How we've transformed the Earth for our benefit and convenience! But a few hundred miles up or down there are no humans. Apart from a thin film of life at the very surface of the Earth, an occasional intrepid spacecraft, and some radio static, our impact on the Universe is nil. It knows nothing of us. -Carl Sagan
