So if it isn't plastic made from fossil fuels, what do you suggest? Apparently the global human mass excluding humans themselves who comprise 0.01% of the global biomass but including our constructions in concrete, asphalt, aggregates, bricks, plastic & glass exceeded the global biomass back in 2020. The same report claims that this anthropogenic mass doubles every 20 years. I wonder what the thermal capacity of all this is let alone other manifest concerns. https://doi.org/10.1038/s41586-020-3010-5 https://doi.org/10.1038/s41586-020-3010-5
