When I went to school at the University of Vermont (a notorious "hippy," "tree-hugger" school) I realized that golf is not the enemy to the environment. I was an Environmental Studies major with the focus of "Golf and the Environmemnt" and attended classes with other UVM students that had the desire to save the rainforest, save the environment, and save the world in general, (to which I meekly declared that I wanted to build golf courses: "winning the war against trees"
).
Golf courses are better to the environment than most social constructs of human civilization; the simple permeable vs. non-permeable discussion of a golf course vs a strip mall or parking lot (etc) is undeniable. Granted, a golf course may cut down trees but the water filtration and preservation of open space greatly exceeds the CO2 potential of the 500 trees that the CC just culled.
I am a pure environmentalist at heart but I have come to terms with the fact that golf is not one of the ecological offenders (except maybe the "tropical island par 3").
