Ubiquitous Plastic
Have you noticed it? Its lying everyywhere you go, be it a gorgeous fort, a beautiful valley, virgin lands, etc etc. It's everywhere. It's litterred in various forms, be it wrappers (zarda wrappers), covers, bottles, cups, etc etc. People whereever they go, they leave their mark their with whatever plastic they have. They have to do it, otherwise their trip is not fruitful.
This act of leaving plastic is not just restricted to people who don't know the harmful effects of plastic to environment. Most of us who know the harmful effect do it, either knowingly or unknowingly do it. Oh well, some people just throw whatever they have in their hands, when they are done with it. Asking them to do drop the trash in the dust-bin, would be of no use. They would also come up with this question - "Do you know whether the trash in the dust-bin is going to be properly disposed ?".
