If you can change the world to be better with your writing or with speaking, what will you write or speak up to the world?

If I had the opportunity to speak up in front of the world, I want to convey about the dangers of passive smoker. It is uncountable how many victims of lung disease than non smokers. Caught in a circle of smokers, makes passive smokers have the 30 percent potential affected deadly diseases from lung spots until the lung cancer. If passive smokers live together with  active smokers, the chances become greater. Because it is possible the person is exposed to smoke every day, so the accumulation of these chemicals even greater.
If you are passive smokers who do not want lung cancer, stay away from places that have smoke and try not too close with active smokers. Multiply and consume foods that contain antioxidants and healthy life patterns. For active smokers, smoke on the places that have been provided, according to the rules, and as far as possible. Think about the safety of the other people. Do not be selfish. Go away from the people closest to you, so they not become victims.
