Why don't you just go naked? That way you're not using any resources whatsoever and not exploiting anyone. Look, everything you do cannot be 100% good for every human being and every blade of grass on the earth. Let me give you an example:
If we don't buy products that are made in foreign sweatshops by underpaid employees, then those sweatshops will be forced to close their doors. Then what do you suppose happens to those people who used to make a dollar a week? They become unemployed and now make nothing a week. To those people, a dollar a week is certainly better than nothing, and without it, instead of being poor, they and their families will surely starve to death. Not every country has the foolish generosity of the Untied States when it comes to governmental aid. So, while you sit in the comfort of your own home, in front of your thousand-dollar computer, with your fifty-dollar non-bleached, natural hemp shirt on, eschewing the purchase of "sweatshop-products", some little girl in Indonesia is hoping she'll make enough money sewing the soles of sneakers to feed her five siblings. So, I'll hope you'll keep it in mind that sometimes what is good for you is not good for the rest of the world, including our fellow Homo Sapiens.
