air pollution is one of the most worrying problems of our time. this problem surfaced during the industrial revolution. the great industrial revolution brought about many positive changes to the world; better transportation, cheaper products, and a better life. however, with it’s riches came the price, pollution. at the beginning of the industrial revolution, no one paid any attention to the problem of pollution. as the science, progressed people started to realize this problem.

air pollution arises from many sources. the burning of gasoline in automobiles produces harmful gases and incineration of products. from various factories come millions of particles that are carried off in the air. chemical plants produce gaseous by-products that are toxic when their concentration is high enough. as parts of the world become more industrialized, air pollution has generally increased and new health hazards have developed. air pollution can result from causes that we can not control. for example, forest fires, dust storms, and volcanoes.

so, all in all air pollution is actually the addition of any harmful substances to the atmosphere, which causes the damaging of the environment, human health and the quality of life. with the development in industry, came along the increase in air polution, which occurs inside homes, schools, offices even in the countryside. consequently there has been an increase in the death rates resulting from various diseases caused by air pollution varying from breathing problem to lung cancer. air pollution does not only affect people but it also damages the whole ecological system in which plants and animals are harmed as well. air pollution has reached such a critical stage where it affects the earth's atmosphere as it lets in more harmful radiation from the sun. consequently, our polluted atmosphere is becoming a better insulator, thus, preventing heat from escaping back into space. that is why there is a global rise in temperature which scientists refer to as "the very global warming". as a result of this rise in temperature the world food supply and sea level will be affected, also there is the probability of increase in the tropical disease.
