I wonder, how much of that I get everytime I brush my teeth.
I was well on a road to organic gardening by that point, and one day while sweeping, I had picked up the broom and noticed that the bristles were abraded. The plastic bristles. Well fuck. There's only one place all that plastic is going and that's into my yard. So I popped off the head and dumped it in the trash (the handle had not committed any crimes, and they are reusable, which can save a bunch of space). There are several natural fibers that are about as tough as plastic, but they're exotic so I couldn't tell you how long the carbon footprint is, but at least I have less plastic in my yard.
The dryer vent, however, is an unsolved problem.
