"... No matter how we touch Mars, we'll never touch it. And then we'll get mad at it and you know what we'll do? We'll rip it up, rip the skin off, and change it to fit ourselves."
– "We won't ruin Mars," said the captain. "It's too big and too good."
– "You think not? We Earth Men have a talent for ruining big, beautiful things..."
("The Martian Chronicles", Ray Bradbury)
