How economic development causes environmental degradation? Explain.

1. Air Pollution: It occurs when greater reliance is placed on mechanisation and automation. Greater use of energy like of coal, kerosene oil and diesel causes greater emission of smoke (and pollutions) in the air. It causes a serious damages to public health. Expenditure on public health owing to environmental pollution is becoming an alarming component of social cost of development.

2. Water Pollution: Process of development has shown a phenomenal rise in industrial production. In the context of environment pollution, growth of textile industry merits a special mention. The process of bleaching and dyeing in the textile industry is passed on an intensive use of chemicals. Industrial waters are often channelised into rivers and canals of the adjoining areas. It causes water pollution. The consequences is obvious spread of water-borne diseases. Implying damage to human life as well as animal life, particularly the sign, the survives largely on water.

3. Noise Pollution: The process of mechanisation and automation (which is the hub of production activity these days) is well known for noise pollution. Machines must produce noise and greater the horse power, greater the noise factor. Unwarranted noise is a great irritant and it erodes the quality of life. In the unorganised sector of iron and steel production, one often encounters deafening sounds which indeed are injurious to public health.
