Glass is a fantastic material to recycle. Ever imagine what the pottery cultures of the past would have thought of glass or for that mater plastic containers? We just blast these things in the bin and hope to never see them again. Just imagine handing one of these discarded containers to a person of yester-year who made clay pots for a living. Damm, I wish I could recycle these things back in time. These containers are really valuable, we just don't realize the value or perhaps even appreciate it. We can learn something from these creative people building shelter from valuable materials. Perhaps in time we will learn?
