On my walks along the streets that border the complex where I live, I pick up trash. The ethic among the condominium owners is to do what they can to keep up the common areas.
My contribution is to pick up trash. I’m out walking anyway. If someone else want to pick up trash, they’re welcome to. There’s enough to go around.
I pick up a lot of cigarette butts. My sense is that smokers are smoking Marlboros in preference to other brands.
On the other hand, perhaps Marlboro smokers are wont to toss their butts out the windows of their vehicles, but smokers of other brands don’t.
Put that in your pipe and smoke it.
