"It is not simply what a society does to its women, racial minorities, handicapped, children, or future generations, but what it does to its fauna, flora, species, ecosystems, and landscapes that reveals the character of that society."
-- Holmes Rolston, III (moral philosopher, academic, writer) (Essay: What is our duty to nature? (2004))
