Yeah, in Philly we'd be able to collect this much within a 30 foot radius of our apartment building. Looks like Philly has a Spring Cleanup in April (from 2019). If 5% of residents were out, I bet we could clean up a large amount of the litter in West Philadelphia. Would really transform the area.
A couple months ago, there was a panhandler near our apartment who asked me for money. I had just seen him litter a plastic food wrapper. I said I don't have any money but will pick up your litter for you. He was neither happy nor mad that I picked up his refuse, but perhaps he'll reconsider littering in the future.
