I hate litter, but I don't see much difference between something biodegrading over tens of years or never. Given all of the advantages plastic has over everything else, I would much rather we used that. We could penalise people who improperly dispose of waste - this seems to work quite well in Singapore.

Paper is a particularly bad replacement as it falls apart when wet - a couple of days ago a paper bag did this to me as I walked back in light rain. Additionally, paper necessarily has a higher environmental cost due to the weight and packing fraction of the raw materials.

I shared that number because it shocked me and the report looked authoritative. Thanks for helping to add context to it :)
