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. We have to use our scientific knowledge to correct the dangers that have come from science and technology.
