Lets be honest with ourselves for a moment. In the long run, most of us don't think about the environment outside of what directly affects us... hot days, smog, litter in front of our house - that sort thing. At the end of the day, the economic burden we face on a business or personal scale is the price tag that weighs heaviest, and this is a key facet of sustainability. If we take a moment to rethink the economics of something as trivial as tossing out an old junked computer, the idea of "garbage" can be viewed in a whole new light. Consider the amount of time, money and energy spent in acquiring and transporting the materials, not to mention actually making the thing in question.
