Environmental Pollution and Protection in Our City
In our city, environmental pollution has become a serious problem. The air is often dirty and smelly because of the waste gases from factories and cars. The rivers and lakes are polluted with waste water from factories and garbage thrown by people. There is also a lot of litter on the streets.
There are several reasons for this. Factories pour a large amount of waste water and harmful gases into the environment without proper treatment. People also have some bad habits. For example, they throw garbage everywhere and don't pay attention to environmental protection.
To solve these problems, we can take the following measures. First, the government should make stricter laws to limit factory emissions and punish those who pollute the environment. Second, we should raise people's awareness of environmental protection through education. People should be encouraged to use reusable products and reduce waste. Third, we can organize more volunteer activities to clean up the streets and rivers.
In conclusion, environmental protection is everyone's responsibility. We should work together to make our city a cleaner and more beautiful place.
