The variety of life in nature can be compared to a vast library of unread books, and the plundering of nature is comparable to the random discarding of whole volumes without having opened them, and learned from them. Our critical dependence on the great variety of nature for the progress we have already made has been amply documented. Indifference to the loss of species is, in effect, indifference to the future, and therefore a shameful carelessness about our children.
