Realize we literally cannot stop making plastic. If we did, modern civilization would collapse. All PCBs and electric devices have some type of plastic in them, including wires and plugs. The only way to read this comment is via plastic.
Plastics are incredibly useful and enable modern society as you correctly point out. In an ideal world, governments would at least phase out single use plastics.
I always think of modern medicine and how much plastic is involved there.
We could make a lot less without collapsing modern civilization though.
