The problem is that most of your neighbours and friends would see you as the hippy idealist guy who gave up apples in vain, because while you don't use apples anymore, airplanes full of apples keep flying, apples factories and farms keep producing and consuming apples, and apples provider ads keep showing how cheap apples are. There's a sense of helplessness (learned helplessness, some would say), due to the perception that your efforts are pointless, as you are but a drop in the ocean.
