The cigarette thing pisses me off. We have some beautiful nature trails in my city, and there is a bylaw against smoking on any of the nature trails or parks. The trail I frequent the most is along the lakeshore, and there are signs literally posted everywhere that say "NO SMOKING". Do you think anyone listens? Hell no. Not only do they smoke along the trail, they leave their butts all over the path, in the sand, near the water, etc. Cigarette butts injure and kill wildlife and can also be harmful to children (if your child is playing in the sand and they decide to shove a cigarette butt in their mouth, for example). And the interesting thing is that most of the people I see actually smoking on the trail are fatties. I guess it's no surprise - they don't give a shit about their bodies, why would they care about anything else?
