Smoking in public places

I would like to put my opinion about this topic I think smoking is not good in public places or not .when we wak in some pleases like malls or park we get out to find some thing to relax to smile fresh  air but with smoking it will be horrible .Smoking in public places is sources other righ to get clean air.Also it is way to encourage children to smoke because they're see the  adults are smoking  I'm not agree  with somke any where it is loost money, health ,air pollution, disturbance and not good model for childer.
