Is it necessary to forbid smoking in all public areas? It is increasingly admitted that smoking is harmful for health and more governments have taken action to limit this kind of negative behavior in some public areas. Even though some people insist that smokers should be allowed to preserve their own rights if they do not make troubles with others, the number of smokers is decreasing among the younger generation. In my own country, a relative law was introduced to keep individuals from cigarettes, especially in restaurants, airports, high-speed trains, which is beneficial for non-smokers from ‘second-hand cigarette’. On the other hand, for smokers, banning them from smoking is likely to constrain their freedom by chains, as if they are poisoning the public. Breaking the law means to take high risk that would be published by the government and be blamed by others, so they usually decide to keep silence instead of announcing their own rights. As a non-smoker, I am glad to see the government are trying their best to isolate its citizens from this harmful hobbies, so that more non-smokers are able to enjoy fresh air in public circumstance. To keep youngsters away from smoking, however, is a long-term tough task for both the governments and the public, and as a result of which, our offsprings will be easy to obtain good habits, and could live longer lives. In conclusion, even if smokers are suffering from the forbidden rules, it is an effective measurement to rise our standard level of living by forbidding smoking in public areas.
