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.
A new survey by researchers at Oregon State University and the U.S. Environmental Protection Agency of more than 600 rivers and streams in the western United States found widespread mercury concentrations in fish.
Though few of the more than 2,700 fish analyzed in the study contained alarmingly high levels of mercury, the prevalence of the element throughout 12 western states caught the researchers somewhat by surprise.
You can absolutely bet when a marketing department uses the word "ethical" - about its lingerie - someone is out to make a buck at your expense. And they think you will believe anything, my environmental friends.
Sacred flaming temples, gas-guzzling RVs that converge for a week on the dry Black Rock Desert lakebed - The Exxon-Mobil National Convention, you are thinking?
Not at all. It's the Burning Man Art Festival in Nevada and it causes global warming. For 21 years this ecological disaster has been using gas-powered generators, up to 37,000 of them, so that smelly hippies can gorge themselves on wasteful fossil-fuel consumption. San Francisco scientists are unsure how much this contributes to global warming but they intend to find out.
