Dky5 19 smoking is a very common phenomenon in today's society. From elderly grandparents to teenagers, they are constantly taking the poison of "chronic suicide". Everyone knows that smoking is harmful to health, but few people really understand the harm of smoking. O I don't know if you have paid attention to it. The outer package of every cigarette says: Smoking is harmful to health. It is reported that millions of people in the world die of various diseases every year, among which smokers account for about 25%. This is by no means a small number. O A's "chronic killer" is only eight or nine centimeters long, but it is so heartless. O In order to prevent such a tragedy from happening again in the next century, the United Nations has set up a "Quit Smoking Day", and countries have successively formulated their own "cigarette laws". To control the growth of death population, o smoking is not only harmful to smokers themselves, but also harmful to people around them, because the smoke from smoking is still harmful to non-smokers and more harmful than smokers. This is called passive smoking. O While protecting our own health, we should also protect our living environment, because the smoke released by cigarettes is toxic. It contains a lot of harmful gases such as carbon dioxide, which is one of the important reasons for air pollution in public places. O So in order to protect our home, we should start with teenagers and me and carry out extensive and in-depth publicity on smoking restriction and smoke-free: For everyone's health, please don't smoke!
