I'm more comfortable tossing an apple core than I am with an orange or banana peel. As far as cigarettes, I know someone who will pull off the tip containing the end of the tobacco and crush it with her finger or shoe. That part will blow away and degrade. The icky filter is saved for the trash. And I'm with bork about the ditch. I constantly find beer bottles and cans, Hardees bags, and all kinds of other neat stuff in front of my house down by the road. Since my ditch is wet over half the time, it's really hard to clean this stuff out.
