The species, Homo sapiens (human beings) appeared late in the Earth’s history. Nevertheless, they were able to modify the Earth’s environment as a result of their activities. The early human beings lived in harmony with the environment. It was only when the human population started increasing and technology improved and expanded that the various kinds of population related to the environment arose. In the developing country like India increasing need for food and firewood has resulted in deforestation and cultivation of steep slopes, causing severe erosion. The ozone layer that shields us from the sun’s harmful ultraviolet rays is being damaged by the increasing use of industrial chemicals called the chlorofluorocarbons (CFCs) that are extensively used in refrigerators, air conditioning, cleaning solvents, packing materials and aerosol sprays. The more people there are in an urban area, the more the cities tend to sprawl and thus, there is an increase in the use of vehicles. Vehicle exhausts release a mixture of chemicals including carbon monoxide, sulphur dioxide, nitrogen oxides and hydrocarbons that adversely affects the environment. The Central Pollution Control Board (CPCB) of the Government of India maintains records of atmospheric pollution levels in many cities around the country. These data show that in many cities, air pollution reaches unacceptable levels on several days of the year. The World Health Organization has classified Delhi as one of the ten most polluted cities in the world. Largely the industrial, agricultural and domestic activities are responsible for deteriorating the environmental quality. Thus, proper enforcement of regulatory measures is required for deteriorating the environmental quality.
