Why is that? Without a car I'd be eating loads of cattle, plants, grains, etc, nevermind all the water it takes to grow all that (something like 1000 gallons per 1lb of beef) and the transportation costs to get it all to my plate. It'd take me about 2600 calories a day EXTRA to get where I need to be, and to eat healthy it'd cost me a heck of lot more than I pay in gas.
I understand the appeal of a car free lifestyle, but the eco friendliness touted by some may be exaggerated, or at least not something a blanket statement can be made about.
The 1000 gallons of water per pound of beef "produced" should be more inciting of a riot than my "cliche" statement.
So reducing your cylinders or consumption wont reduce the burden?
How about living in a desert? Not alot of rainfall and natural agriculture going on there? Truck it in anyway, perhaps reroute a river for water - hell were in a desert and we need some water! Thats Eco stupid...or human population location stupid?
Im also a big time doubter and agree with your sentiment...question everything!
Peace!
