  18. 18. Other planets have sunlight, but the Earth is the only planet we know that has air and water. Without air and water, the Earth would be unable to sustain life.  A diverse community of plant and animal life has thrived on this planet for millions of years, sustained by the sun and supported by the soil, water and air. 
  19. 19.    Air quality is important simply because we can’t avoid breathing in the air around us. Man can survive without food for 5 weeks and 5 days without water but without air???????? not even five minutes The average adult breathes in about 20 cubic meters, or 20,000 litres of air a day! Mass of air taken in is 16 kg./day Those of us who live in cities should be especially concerned, since we are exposed to a greater amount of pollutants coming from automobile traffic, commercial, industrial and manufacturing facilities, as well as other sources.
  20. 20.   Air pollutants can cause a variety of health problems - including breathing problems; asthma; reduced lung function; lung damage; bronchitis; cancer; and brain and nervous system damage. Air pollution can also irritate the eyes, nose and throat, and reduce resistance to colds and other illnesses. Air pollution can be especially harmful to the very young, the very old, and those with certain pre-existing medical conditions.
  21. 21.   Air pollution also causes haze and smog reduces visibility, dirties and damages buildings and other landmarks, and harms trees, lakes and animals. It is also responsible for thinning the protective ozone layer in the upper atmosphere that protects us from harmful ultraviolet radiation from the sun, and may be contributing to the phenomenon known as global warming- the steady increase in average temperature of the global climate.
  22. 22.    Historical explanation With increasing urbanisation and Industrialisation, humans started to release more wastes into the atmosphere than nature could cope with. Since then, more pollution has been added to the air by industrial, commercial and domestic sources. As these sources are usually found in major cities, the gases that are produced are usually concentrated in the air around them.
  23. 23.   The adverse effects of air pollution were graphically illustrated in London in 1952 when, in just a few days, an estimated 4000 people died from effects of fine particle pollution. It is when these concentrated gases exceed safe limits that we have a pollution problem. Nature can no longer manage air pollution without our help.
