I live in Son La, Vietnam. Habitat, some clean places, some heavily polluted. But the environment is currently severely polluted. Environmental pollution is also controlled by us, air pollution: Dust generated by industrial plants. Water pollution due to: chemical fertilizers and pesticides leach into groundwater and pond water; Domestic wastewater discharged from riverside residential areas causes serious pollution, affecting the health of people and living in the area. Thus, polluted environment is a threat to human life. We need to hit the alarm bell to wake up people, need to jointly protect the environment.
Many cities have a serious pollution problem. Motor vehicles, factories, and other sources create so much air pollution that it may hang in the air like dirty fog. Air pollution threatens the health of the people who live in cities. City wastes cause water pollution when they are poured into waterways. These wastes kill fish and make some areas unfit for swimming. In addition, many large cities have difficulty disposing of their garbage. The amount of garbage grows each year, but places to put it are quickly filling up.
Citizens, governments, industries, scientists, and business people must work together to gradually reduce pollution. For example, most cities have introduced recycling programs, which cut down on garbage and the space needed to store it. Residents spearate recyclable produces from garbage, and city governments provide drop-off cities or pick up the products from homes.
