【英语作文雾霾】In recent years, the problem of smog has become a major concern for people all over the world. Especially in big cities, smog often appears during winter, making the air very dirty and difficult to breathe. This kind of pollution not only affects people's health but also brings many problems to our daily life.

Smog is mainly caused by the burning of fossil fuels, such as coal and oil. When these fuels are burned, they release a lot of harmful gases and fine particles into the air. In addition, the increasing number of cars on the road also contributes to air pollution. These pollutants mix together and form a thick layer of smog that covers the city, reducing visibility and making the air hard to breathe.

The effects of smog on human health are very serious. People who live in areas with heavy smog are more likely to suffer from respiratory diseases, such as asthma and bronchitis. Children and the elderly are especially vulnerable to these illnesses. Long-term exposure to polluted air can even lead to heart disease and lung cancer.

To deal with this problem, governments and individuals need to take action. The government should strengthen environmental regulations, encourage the use of clean energy, and promote public transportation to reduce the number of private cars on the road. At the same time, people should raise their awareness of environmental protection. For example, we can choose to walk or ride a bike instead of driving, and we can also plant more trees to help improve air quality.

In conclusion, smog is a serious issue that needs to be addressed. Only through joint efforts can we create a cleaner and healthier environment for ourselves and future generations. It is everyone's responsibility to protect the air we breathe.
