Hazardous substances are everywhere around us, even in the air we breathe. The industrial era introduced many benefits into the human lives but, on the other hand, it polluted our environment with many kinds of gases, droplets and particles. The air is polluted in both the city and the country, only the sources of pollution differ from one place to another. In the city, vehicles are the main sources of pollution while in the country, the agricultural industry the causes air pollution. The effects of air pollution is very bad. Thanks for sharing Video.
