Paragraph 1: Causes of Air Pollution
Air pollution is mainly caused by human activities.(车排放量+工厂浓烟
Vehicle emissions are a major culprit. Cars, trucks, and buses burn fossil fuels, releasing harmful pollutants like carbon monoxide and particulate matter.
Industrial processes also play a part.
Factories emit large amounts of chemicals and smoke into the air.
Paragraph 2: Problems Caused by Dust in the Air
Dust in the air can bring various problems. It can reduce visibility, which is dangerous for transportation, especially on roads and in aviation. Moreover, fine dust particles, known as PM2.5, can penetrate deep into our lungs. This may lead to respiratory problems such as asthma, bronchitis, and even lung cancer over time.
Paragraph 3: Opinions and Measures to Protect the Air
Air pollution is a serious threat to humanity. We must take action.
We can start by using public transportation more often, cycling, or walking to reduce vehicle emissions.
Industries should adopt cleaner production methods and install pollution-control equipment. Additionally, planting more trees can help as they absorb pollutants and release clean oxygen, making our air healthier.
