Activist Mike Vandeman has taken a radical stand on such matters. He began with the readily-observable fact that mountain bicycle trails are composed of gullies and ripped-up soil, and from this, drew the conclusion that mountain bicycles are as harmful to the environment as motorized vehicles. Predictably, he caught backlash from the mountain cyclist community, who -- like everyone nowadays -- like to portray themselves as environmentally aware. To their discredit, however, some among them have stooped to the same sorts of tactics Creationists use: deliberately taking Vandeman's words out of context, to try to make them seem ludicrous. But suppose it was me? If someone like Vandeman criticized my favorite outdoor activity, could I take an objective view?
I once read a spoof on "ecotourism" -- a very simple writing, simply a comparative list of all the characteristics of ecotourism, and all the characteristics of regular tourism. The humorous point was, the lists were nearly identical. For example, both lists mentioned burning up huge amounts of fossil fuels to fly to and from the destination; both lists mentioned eating well on imported foodstuffs while the local populace suffered in poverty and hunger; both lists mentioned emphasizing Western superiority by bringing digital camcorders and other high technology. In fact, the only difference between the two lists was one single word in the final item:
Ecotourism: spend time looking at flora, fauna, and natural landscapes.
Regular tourism: spend time not looking at flora, fauna, and natural landscapes.
I look back on my life of vagabondage, and I find I have left some very big footprints. How many plastic and aluminum containers have I thoughtlessly thrown away? How much fossil fuel has been burned in getting me from point A to point B? How much agricultural pollution has resulted from producing the foods I have eaten? For all my high-sounding ideals, in practice I have done little better than the average eco-slob.
Changes have come about as a result of this awakening. Whether at home or travelling, I make as much of my food as possible the unpackaged kind; I became a vegetarian; and I travel overall lighter, having found that stuff is usually more of an encumbrance than a convenience. Ordinary tourism has lost its appeal, as I think more and more of how to make my presence matter. In this, I am not unique -- there is a wave of young people with just such ideals, preferring to do overseas volunteering rather than mere travel. Ironically, this is a move away from "leave only footprints" and toward leaving a legacy.
