Mumbai bans plastic bags, bottles, and single-use plastic containers
Instead, government could've imposed ban on the consumer products which are wrapped using plastic material. Almost 50% plastic come directly from such consumer products sold by all FMCG companies. Such plastic material which is used as a wrapper (e.g. mineral bottles, wrappers of chocolates, biscuits, wafers, tobacco, etc.) is often useless and people tend to throw it right away.I agree that "we", the people need to take a pledge to stop using plastic as much as we can. But if there's no restriction put on giant FMCG companies such as Hindustan Unilever, ITC, Patanjali, Netsle, Procter and Gamble, etc. from supplying their products wrapped in plastic, I consider all of these government initiatives merely as a gimmick.EDIT 1: 
Another comment I left on this thread - https://news.ycombinator.com/item?id=17400028.EDIT 2:
In India, plastic is a major contributor of blocking sewers and rivers, especially in rainy seasons. Another important problem plastic waste produces is that since government bodies (such as, municipal corporations, gram panchayats, etc.) are unable to dump and/or recycle plastic waste properly, it is accidentally consumed by animals and is the major reason for their deaths. Another issue is that, often "dumping waste" is considered as "burning" it. Burning plastic waste disturbs healthy air and is a major factor among others responsible for the increased air pollution in Indian cities recently.
