The Puma Blues #1

"... We must do our utmost to maintain the diversity of the earth's animals and plants.  It is not just that we depend on many of them for our food - though that is the case.  It is not just that we still know so little about them or the practical value they might have for us in the future - though that, too, is so.  It is, surely, that we have no moral right to exterminate for ever the creatures with which we share this earth." - David Attenborough
