Absolutely 'Correct' as 'Ecology' Protection is the responsibility not only of 'Governance' but also of 'Inhabitants'

PM2. 5 in indian cities round the clock in danger zone resulted 'Cancer' or abnormal growth of cells in human body

The level of population in Delhi on Deepawali is 999

I think it is correct.

What are the precautions we can take to prevent pollution

Adequate 'Green' with unban population

Sure sir @Pankaj Tomar

Undoubtedly correct. The sound of bursting of crackers is unbearable to the infants and aged people. Even fireworks cause immense air pollution.

There should be provision for severe punishment.

Thanks for suggestions sir Subir Bandyopadhyay

I feel that it will work in favour of people's health specially in crowded cities. We should also find out an eco-friendly way to celebrate the festival as we cannot leave a festival all at once.
