In May 1996, I wrote to Prince Philip, the Duke of Edinburgh, in his capacity as President of WWF. I stated in part:
"Myself and many colleagues who specialize in forest science are distressed at recent statements made by WWF regarding the environmental impact of forestry. These statements indicate a break with WWF’s strong tradition of basing their policies on science and reason. To the best of our knowledge, not a single species has become extinct in North America due to forestry."
