The growth in the size of the human population has caused an increase in the demand for food, water, home, electricity, roads, automobiles etc. These demands exert tremendous pressure on our natural resources and thus contribute to environmental pollution. It is, therefore, extremely essential to check the degradation and depletion of our precious natural resources and pollution without halting the process of development.
The Government of India passed the Environment (Protection) Act in 1986 which is one of the most comprehensive legislations with a pretext of protection and improvement in the quality of the environment (air, water and soil).
The Air (Prevention and Control of Pollution) Act came into force in 1981 with the pretext of prevention, control and abatement of air pollution.
The Air Act was later amended (make minor changes) in 1987 to include noise as an air pollutant.
