Question

Explain how pollution is spread.

Answer 1

Pollution is spread through air, water and land due to various human activities. Industrial and commercial wastes release harmful substances into the environment. Vehicles and transportation add smoke and harmful gases to the air. Agricultural activities such as the excessive use of fertilizers and pesticides pollute soil and water. Domestic waste, sewage and garbage also contaminate water and land. Rapid industrialization, population growth and urbanization further increase the spread of pollution. Noise, heat and light from industries, vehicles and other human activities also cause pollution. Thus, pollution spreads widely through human activities and affects the natural environment.
