Pollution

Do you know that the ultimate cause of pollution is human activity itself. Pollution is a human contribution to nature. Science has evolved technologies and technologies have helped the human welfare. In the process, the pollution has been a part of technology and therefore a part of human miseries.

Human activities mainly include:

·         Industries for various human needs - directly and indirectly

·         Agriculture for food production and industrial needs

·         Health care for health of human beings and animals

·         Transport for mobility of human beings

·         Dwelling for settlement in city or villages

·         Energy for various direct human needs and industrial needs.

All of them contribute to pollution in one way or other and therefore cause miseries. All of them are aimed to be part of human welfare programmes. Along with welfare, all of them have brought the maladies of pollution.

In others, it may be invisible, indirect or negligible. In such a broad sense, no industry is free of pollution.
