In the village I used to tell children not to throw away the plastic wrappers from the hard boiled sweets I used to get them. I would scold them and make them pick up the wrappers and put them away in another cover. When the village people going to the weekly santa (village market for provisions and vegetables) started bringing back their weekly provisions in a plastic cover got there, instead of their cloth bags, I would give them short lectures on the evil of plastics. They are polite, civilized, and would listen earnestly.
The damage I unleashed was far more than all of theirs together. My moral superiority was also far higher than their. ( And I did not face that there is no ‘proper disposal’ of plastic. I could just move it out of my village into another small town !)
I represent the 'concerned' citizen. The 'educated' citizen.
