The current environment is heavily polluted by industrial wastes, domestic waste, dust, and traffic. With the pace of population growth and the pace of industrial and industrial development As the current urbanization, the area of cultivated land is increasingly narrowed, the quality of land is increasingly degraded. Polluted water reduces biodiversity in water. Water pollution is caused by water, industrial wastes are discharged into river basins but not treated properly; chemical fertilizers and pesticides that leach into groundwater and pond water; Domestic wastewater discharged from riverside residential areas causes severe pollution, affecting the health of people and living in the area. Air pollution is caused by exhaust gases of the factory, the emissions from the vehicles make the air unclean or cause bad odors, reduce vision when looking away due to dust. 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.

Nowadays, big cities are facing with air pollution, one of the most serious global issues. One of the causes is vehicular traffic. The combustion of the automobile fuel whether it is diesel or petrol, that powers a vehicle, leads to the release of poisonous gases released through the exhaust of the vehicle. Smoke generated by factories is also let out into the air leading to pollution. Moreover, the burning of fossil fuels such as coal, as also the burning of wood for cooking, and of farm wastes lead to harmful smoke polluting the air. Air pollution always has bad effects on our life. People around the world are suffering from respiratory and cardiac problems, and diseases such as cancer affecting other organs of the body too. To improve the air quality, people should plant more trees and use pubic transports instead of private vehicles.
