When physical, chemical and biological projects of the different components of environment: air, water, soil, noise change to the detriment of living of humans it may be said that environment has been affected. Many developing countries are placing more and more reliance on industrialization. It is not only a mechanical but also a social process.
Therefore it affects the environment physically as well as socio-culturally. All aspects of pollution are directly or indirectly related to human health and well being. The excessive growth and rush of people from villages to urban areas resulting in over crowding of cities. Rapid urbanization and industrialization have led to an increase in environmental pollutant load that poses serious public health problem. It also affects the socio-cultural environment with the close ties of groups coming under pressure. Traditional ties are replaced with new work based ones. Religion becomes secular. Thus industrialization affects the social fabric making the society more materialistic.
