The owners of industries dump waste material on the surface of the earth or in rivers. So, water is polluted and the waste on the earth produces different poisonous gases which pollute the air. On the other hand, forests where purity air have been cut down and new cities and industries have been established in their place. The cutting of the forests causes what is called "The Green House Effects". It results in the heating of the earth's surface which has serious consequences for life on this planet.
As a result, generations to come are likely to suffer from a number of incurable diseases. Timely measures must be taken to prevent the 'Green House Effect'.
Paper pollution of public life and morality through Newspapers, Magazines, Journals etc. This kind of pollution is closely related to moral pollution, the results of our materialistic greed. Corruption is wide-spread in every walk of life. Bribes are fearlessly given and accepted and laws of the land are evaded in very clever ways. Character-assassination is another form of this moral pollution.
Trees and plants turn carbon-dioxide into oxygen but when they are cut down, the air is not purified. Deforestation also causes soil erosion. The rich soil is either washed away by water or blown away by the wind. So artificial fertilizers are used to maintain its productivity. Polluted water is used for watering the plants and vegetables. In this way, vegetables and crops are polluted. Pesticides are also a source of pollution to our crops, vegetables and fruits.
Water pollution resulted in the outbreak of cholera and gastroenteritis in a number of colonies of Delhi suffering and death on a large scale. Water pollution has assumed alarming proportions and urgent steps are needed to control it.
Intensive research is essential to solve this problem. Late Mrs. Gandhiji's call for co-operative research, made in another context, is very prudent and farsighted and her suggestion cans profitably be applied to this field also. This is the only way out for the generations to come.
