The argument that is pro-polyethylene plastic bags over cotton completely ignores the source: Renewable plants that are grown and harvested, vs. finite fossil fuels extracted from the Earth and refined.
> Instead of a simple blowing and sealing process, the cotton must be made into yarn, woven into fabric, prepared, dried, sized, dyed, and finished, which takes around 1,725 megajoules, around 3,050 times as much energy.
That conveniently ignores the drilling, extracting, transporting, refining, and transporting again to make "polyethylene resin".
