Why is smoking harmful
Smoking is bad for your health. It can cause diseases of the heart and lungs. Every year, millions of people around the world die as a result of smoking. That's terrible!
If you smoke, you harm yourself, but you're also harming the people around you with your second hand smoke.
Smoking pollutes the environment, too. Everyone wants to live in a clean environment and breathe fresh air. In many countries, smoking in public places is now against the law.
What should we do
Never touch cigarettes. Whenever someone offers you a cigarette, you should always say no. Don't take that risk.
When somebody talks about smoking, change the topic.
If your family members smoke, encourage them to stop smoking. It will be hard for them, but you should try explaining how important it is for their health.
Eat more fruits and vegetables, do more exercise, and form good habits.
Once you get into the habit of smoking, it's not easy to give it up. Stay away from cigarettes and you can live a long, healthy and happy life.
No smoking, please!
