As a younger man, I was a big fan of Greenpeace.
As time went on, I thought they lost their focus by branching out from protesting nuclear weapons to whaling and trees and basically hanging out a shingle that said, "If you send us money, we will protest for you."
I watched them change from instilling their people with scientific literacy to educating their people on political activism. Then I watched them turn on me because I was a scientist who didn't much like exaggerated evidence in the name of fundraising and because I was a sportsman and because I was a businessman.
I've always believed that sportsmen - hunters, hikers, mountain climbers - are natural allies of the environmental movement.
