That land is a community is the basic concept of ecology, but that land is to be loved and respected is an extension of ethics. - Aldo Leopold

If we lose our wilderness, we have nothing left, in my opinion, worth fighting for; or to be more exact, a completely industrialized United States is of no consequence to me.

One swallow does not make a summer, but one skein of geese, cleaving the murk of a March thaw, is the spring.

Ideas, like men, can become dictators. We Americans have so far escaped regimentation by our rulers, but have we escaped regimentation by our own ideas? I doubt if there exists today a more complete regimentation of the human mind than that accomplished by our self-imposed doctrine of ruthless utilitarianism.
