The advert I have is about smoking , is says ' Don't smoke around children' why it is so important ?

The advertisement which says "Don't Smoke Around Children"
is an important warning regarding the evils of what is called Passive
Smoking. The habit of smoking is a killing habit for the smoker, but the
smoker also causes considerable damage to the people near or around him who may suffer
the similar health-hazards as passive smokers. Since children are the most vulnerable
community and should be best protected against all such hazards, it is strongly advised
that a smoker even while smoking at home or such other private places must be very
conscious as well as cautious about the presence of children around. Quit smoking if you
can. Take every care to see that the smoke you exhale does not cause trouble to
children.
