雾霾英语作文初中

As the days go by, the air we breathe has become increasingly polluted. Among all the environmental issues, smog has become one of the most serious problems in many cities. Smog is a mixture of smoke and fog, but it contains much more harmful substances like dust, sulfur dioxide, nitrogen oxides, and other harmful particles.

In my city, smog appears quite frequently, especially during winter. When smog occurs, the sky becomes gray and the air feels heavy. People have to wear masks to protect themselves from breathing in these harmful particles. Schools sometimes even cancel outdoor activities to keep students safe from the poor air quality.

The main cause of smog is pollution from factories, vehicles, and construction sites. These sources release large amounts of pollutants into the atmosphere. In addition, weather conditions such as calm winds can trap these pollutants near the ground, making the situation worse.

To fight against smog, everyone needs to take action. Factories should be required to use cleaner technologies to reduce emissions. We can also try to walk or ride bicycles instead of driving cars whenever possible. Planting more trees and creating green spaces can help improve air quality too.

Smog not only affects our health but also changes the way we live. It reminds us how important it is to care for the environment. By working together, we can make a difference and create a healthier world for future generations.
