Air is necessary for the existence of all living things so air pollution is one of the most important problems worldwide.
Modern plants and factories send a lot of smoke into air so nowadays it is difficult to breathe in big cities. Enterprises burn oil, coal and wood and produce carbon dioxide that cause destroying the ozone layer and climate changing.
Because of the Industrial Revolution factories spew out smoke and chemicals that had never been in contact with human lungs before. As a result, people have new diseases, allergic reactions, and poor health.
Aerosol sprays and other chemicals also destroy the ozone layer which protects the Earth from ultraviolet radiation which comes from the sun.
Air pollution has a negative impact on water quality. Air pollutants can be deposited on land and water, sometimes at great distances from their original sources.
A further result of air pollution is acid rain. Acid rain basically appears when factories release high levels of sulphur into the air. The sulphur then combines with rainwater to form a weak sulphuric acid. Acid rain itself cannot harm humans but it harms our environment. Over time, the acid rain can kill plants, weaken structures and life in entire lakes and rivers.
Air pollution and destruction of ozone layer are the results of careless handling with nature and requires active measures to prevent environmental disaster.
