A ziploc bag that has been blown into my path from the actual storm, we are experiencing. And of course, I picked it up, and did dispose it correctly.
However, I think that here in this community we do not need such a hint as in the title, as I'm sure we are all very aware that we have to take care of our "only" world.
You have turned this “mundane” into real art. Very nice. Yes, we carry a bag with us for our neighborhood walks just to pick up the trash we see on our trails.
