"No society has ever yet been able to handle the temptations of technology to mastery, to waste, to exuberance, to exploration and exploitation. We have to learn to cherish this earth and cherish it as something that's fragile, that's only one, it's all we have."

Margaret Mead, anthropologist (1901 - 1978) Radio excerpt reproduced by Voice of America, 17 January 2010.
