Mess free

Last week I was travelling from Mumbai to Pune by bus. The bus had a break at food mall. I was roaming around the bus as didnt feel hungry at all. There was another family from the same bus as mine standing nearby. Husband, wife and their 4 years old daughter. Well educated, well dressed family. The man got few eatables in a paper bag. They had all of its contents and the man threw the paper bag there itself in the parking area. I was shocked as the dustbin was really 7-8 steps and very much visible from where they were standing, still they didnt bother throwing it in dustbin. Does well-educated and well-dressed mean well cultured? I was left with a question. Apart from making the place dirty, the man had given his small daughter a lesson to remember all her life - 'Not to bother the cleanliness of public places'
Don’t throw waste anywhere except for the dustbins. Easier said than done. Its easy to follow when we are at home, because we want our home clean and neat; but otherwise we conveniently forget the same basic thing at public places. It troubles us to take 4 more steps to go to public dustbin, or to carry the waste with us until we find a dustbin/reach home.
I will not request to spare any of your time, energy or money to clean the places. Cleaning is of no use as everytime we clean, new waste is added to the place. Instead we can try to avoid adding to the mess from our side.
Can we carry a paper bag or some carry bag everytime we are out and put all the waste in it and dispose it off once at the end when we are done with the bag to the dustbin at public place or the bin at our home. Does it not atleast lessen the mess by 0.01%?
Can we encourage people around us to do the same or ask them to put their part of waste in our waste bags.
Does it take much of our time, energy, money?
Try doing it once and you will feel proud of yourself for at least avoiding more mess/waste to cause a shame to our nation.
