As far as I am concerned there are no conservative enviro-whackos. Prince Charles included.
You know, I remember in the 1960s and 1970s when a large part of the early environmental movement were conservatives. Country people, hunters and similar who were the actual people who lived on the land and spent their time on the land, and understood nature. It got hijacked - especially in the United States by the left after that.
Prince Charles was part of it as part of that earlier movement, and he remains so. His father was President of the World Wildlife Fund for most of the 1980s and 1990s, before it too was at least partly hijacked.
