Nobel Peace prizes are generally given to someone who has worked to inspire or broker more peaceful relations between waring factions of humans. I think the Nobel committee's choice of awarding the prize to the most salient and influential [but hardly the only] parties working to end a war heedless humanity has waged against their own environment is long overdue.
Many wars are ultimately fought because that seems more logical to the waring groups than trying to share the dwindling resources for which they are contending. How much more sensible it is to work instead against wasting those resources in the first place. We have a long way to go before Planned Parenthood or any ZPG/NPG activists get the peace prize but at least we see here a step in the right direction.
