Hopefully energy used will become less important. CO2 emissions seem like the biggest threat to our long term health. Microplastics also matter, a bit.

How much plastic is escaping into the environment from the recycling process vs. landfill? What are the CO2 output of landfill vs. recycling? I imagine burning would be the worst option for these.

Not surprised that the market forces tended towards the most energy efficient waste disposal systems; glad we don't have mountains of trash or poor landfills.

I don't remember energy use being the problem with plastic bags?

It was plastic bags being absolutely everywhere in the environment. Streets, parks, trees. Wrapped around anything sticking out of the ground. On your face on a windy day.

Pollution is the problem with plastic. Probably health, too, now that microplastics are being recognized as an issue.

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".

Every winter in my city, once the leaves all fell, our trees would be draped in shredded plastic bags. Banning single use plastic bags has done a significant amount to beautify this place.
