Walking the streets of any city (other than Singapore) you will probably notice two common items anywhere you go.
1. Chewing Gum
2. Smoking butts
My thoughts on these two things is that they should be taxed to hell with an environmental or litter fee. I will admit I am guilty of spitting gum on the street, but even myself, I need to make an extra effort to make sure that chewing gum ends up in the rubbish.
Smokers and Gum Chewers, try to make sure that your gummy butts end up in the trash. Streets will look nicer!
