We teach our kids to pick up after themselves at home and outside. Schools hand out gloves and teach the environmental message by getting kids to pick up thrash on school grounds (why are the thrash there in the first place?). But would you pick up a potentially bacteria-laden piece of thrash that “just happens” to be strategically left lying on the ground?
If you do, you just might be caught doing something good. Remember to wash your hands afterwards.
