@Nazz Glass like metal, is an infinitely recyclable product. It is efficient, easy and attractive in all generations of use.G lass is neither scarce nor difficult to harvest. It is environmentally inert, it is biologically safe, it does not impact the lives of creatures except to give them a broader degree of spaces to make their home or to accrete to. It becomes a part of its environment and with the passage of time is so totally subsumed as to fade away entirely. It's inherently attractive, like a gemstone. The processes of nature work upon it and make something inherently fascinating and precious to the beholder. Junk glass can be easily taken and wrought by artisans into beautiful things with ease.
Anyone who tells you that recycled plastic is good for the environment is someone who is phony. They care only because the puppet masters of the television race says that they should care. True environmentalism is incompatible with them. They're told to feel a certain way, they feel that way, and seek for ways to lighten the guilt carefully draped around them like a mantle.
They're not possessed by a spirit of stewardship and responsibility. The overwhelming sense of awe and spiritual wholeness nature provides isn't known to them. They're just possessed by a desire to feel less guilty.
They're your moral inferior.
