We all know that smoking is bad for people’s health. But not many people know about the danger of secondhand smoke.

Secondhand smoke is the smoke that comes from the smoker’s breath(呼吸). If people breathe in secondhand smoke from time to time, they could get sick from it.

But how serious is the problem of the secondhand smoke? The World Health Organization(WHO) did a study of 194 countries. They found that secondhand smoke causes about 600,000 deaths every year. That is about 1% of the world’s deaths.

Secondhand smoke is especially bad for children because their bodies are still growing. According to the study, around 165,000 children under the age of 5 die each year because of secondhand smoke. Most of these deaths happen in Africa and southern Asia.

You can do something to keep yourself and other people away from secondhand smoke. You can ask the smokers, such as your parents, to smoke outside. And, if someone smokes close to you, you’d better hold your breath or just walk away.
