@Anonymous Make reading a daily habit, maybe at bedtime. Read to him or her if your child is reluctant at first. Choose adventure or fantasy or mythology, whichever interests the child! For very young children, picture books would be very appealing.
@Anonymous Show them pictures of people who are affected by the smoke. Tell them about animals in distress. Talk to them of the illnesses and even deaths due to fires caused by the manufacture of crackers in ramshackle sheds and huts. Maybe your child can becone the ambassador for a new age of caring for people and voiceless animals!
