उत्तर
I visited a local doctor and learned about the harmful effects of smoking. The doctor explained that smoking causes respiratory problems, heart disease, various types of cancer and a decrease in immunity. In addition, I gathered information from books, articles and the Internet and took help from my teacher and parents. When I found out the percentage of smokers in my area, I found that about 25% of adults smoke. Finally, if someone in my family smokes, I will inform them of the information I have gathered. I will collect all the information such as brochures, articles and notes from doctors and present the facts calmly and respectfully.
In this way, using well-researched information can help smokers understand the serious consequences of smoking and encourage them to quit. The aim is to raise awareness and promote a healthy lifestyle for all.
