          Currently, the air pollution in my city is getting worse and worse. There are many causes of air pollution but mostly from vehicles including trucks, jeeps, cars, and the use of insecticides, pesticides, and fertilizers in agricultural activities has grown quite a lot. Moreover, manufacturing industries release a large amount of carbon monoxide, hydrocarbons, organic compounds, and chemicals into the air.

   Air pollution is also a direct cause of global warming, leading to a series of phenomena, such as the greenhouse effect, ice caps melting, natural disasters such as droughts, floods, volcanic eruptions, and so on. The sea level is rising, more and more natural disasters occur, which threaten all species, make some of which be rare or extinct, break the ecological balance on the Earth. Human beings are no exception. In recent years, we have seen a dramatic increase in the number of people suffering from respiratory and cardiac problems, and affect other parts of the human body. To reduce the air pollution in my neighborhood nowadays, I think everyone should travel by public bus. Planting more trees is also a good idea to clean the air. In short, clean air is very important for our health so I hope in the future the air in my community will get cleaner, people will have better awareness to protect it.
