I don't think we can go back to living in a "steampunk society," where glass, wood, metal, cotton, wool were the basic materials of our lives, as dreamy as it seems. Steel mines, cotton farming, and sheep farms create their own environmental disasters. The solution has to be focussing on using and creating new biodegradeable substances, and saving plastics for where it counts, like medical devices and waterproofing.
The whole disposability of our current society is the problem. But there is no money for Wall Street in reuse, repair, recycle. Ketchup comes in a plastic bottle because it's cheaper to manufacture and ship. Shoes are no longer leather. Car dashboards are no longer wood. Even lightbulbs are now plastic. WE used to buy less, but of better quality. I miss that.
