The problem with plastic is not the CO2, but the fact that we are producing more and more of it and it does not decompose so we now have it in forests, rivers, ocean, fish, drinking water, our bodies... this can't continue, it's not a sustainable path.

If the biodegradable plastic isn't made of oil but something we grow, then it would still be CO2 neutral.

So is petroleum-derived plastic buried in the landfill.

In fact bio-derived plastic buried in the landfill is carbon-negative and should be encourged!
