In this article, you're introduced to the concept of YIMBY - Yes In My Back Yard -- as a method of decreasing the overfill of landfills. We find this passage really illuminating:
"By all standards, yard wastes make up at least 13 percent of the municipal waste stream. Food wastes comprise another 10 percent of the total volume. That works out to about 200 pounds of yard waste and another 150 pounds of food waste per person, per year. These segments alone can reduce our total waste volume by almost one-fourth. The result of a properly managed composting effort can be an economically sensible, environmentally sound, waste management strategy with a value-added end product."
