【关于雾霾天气的英语作文】In recent years, the problem of smog has become a serious environmental issue in many cities around the world. Smog, which is a type of air pollution, is mainly caused by the accumulation of harmful substances such as dust, smoke, and chemical particles in the atmosphere. It not only affects people's health but also reduces visibility and harms the environment.

Smog often appears during winter when the temperature drops and the air circulation becomes poor. In this situation, pollutants are trapped near the ground, making the air very dirty. People who live in areas with frequent smog tend to suffer from respiratory diseases, such as coughing, asthma, and even lung cancer. Children, the elderly, and those with weak immune systems are especially vulnerable.

To deal with smog, governments and individuals need to take action. On the one hand, the government should strengthen environmental regulations, reduce industrial emissions, and promote the use of clean energy. On the other hand, people can contribute by using public transportation, reducing the use of private cars, and planting more trees. Everyone should be aware of the importance of protecting the environment and take responsibility for it.

In conclusion, smog is a serious problem that needs to be addressed urgently. Only through joint efforts can we create a cleaner and healthier living environment for ourselves and future generations.
