I have written a piece for the Dawson Centre, titled,
Pharisees of the New Age:
Environmentalists and How They Went Wrong.
It's in the centre's newsletter (about 1/2 way down the page). I wrote it after it struck me that both the environmental and Pharisee movements started out with good intentions but they became corrupted and they neglected their original mission.
