The move to synthetics, for "environmental" reasons is one which makes me chuckle, or, would, if it were not for the massive devastation of northern Canada and longterm poisoning by pollution of the fifth largest river system on the planet, the Athabaska River. This feeds raw Canadian "crude" to US refineries, which can then supply the Americans with "cheap" oil, which, in turn, is used to manufacture various synthetics.
The hunting/trapping/fishing culture that existed in these regions for roughly 10-12 millenia, did not cause pollution and the various animals were both far more numerous and wide-spread than is the case today.......
I prefer to kill and grow as much of my food as circumstances allow and avoid the huge "carbon footprint" associated with eating foods from foreign venues to supposedly be "environmentally friendly" by not eating what sustained humans here for eons before "vegans" were ever thought of.
I ue down, wool, leather and see to it that I support REAL ecologically sound sustainable activities and avoid polluting industries and products.
