Preface: In this age of science, where humans have got some boons, there have been some curses. Pollution is a curse born out of the womb of science and which most of the public are compelled to bear.
Meaning of pollution: Pollution means - defect in natural balance. Neither pure air, nor pure water, nor pure food, nor a peaceful atmosphere.
There are many types of pollution! Major pollution are air pollution, water pollution and noise pollution.
Air pollution: This pollution is more spread in metros. Around the clock, the smoke of factories, the black smoke of motor vehicles has spread in such a way that breathing in healthy air has become difficult. When the women of Mumbai go to remove the washed clothes from the roof, they get black and black particles frozen on them. These particles go into the lungs of humans with breath and give rise to incurable diseases! This problem is more where there is dense population, lack of trees and the environment is tight.
