I recommend picking up litter while you walk (or run, aka plogging). I recently passed my 1,300th day in a row picking up at least one piece of litter per day. Since the pandemic, more like 20 or 30 since there's so much more litter.

You'll be surprised at how much you learn about your world and community. The goal isn't to fix the world as only one person, but to raise awareness and humility. Lots more. I ended up on TV a couple times for it https://joshuaspodek.com/im-on-tv-again-for-plogging and approached by politicians.

I don't use gloves, but you can. In Manhattan I carry it to the next wastebasket I pass, but you could also bring a bag.
