Human’s life is closely associated with the eco-system, which is the consequence of hundreds of millions of slow evolution of plants, chemicals and atmosphere. Ecology has been defined as surroundings or neighborhood or the entire eco-system of a place in which an organism lives.It is also described as the total cosmos which forms not the world alone but the total universe. Strictly speaking ecology refers to that division of biology which treats of the relations between organisms and their environment. Human beings as organisms are exposed to the conditions of environment of different types-social, physical mental; to which are appended the destructive possibilities. Our environment mainly consists of two major elements:(i) The physical environment comprising land, water and air (lethosphere, hydrosphere and atmosphere), and(ii) The biological environment comprising all living organisms, which provides the food and other materials for the survival and growth of man on the earth.The industrial ecologisation is mainly concerned with physical environmental pollution—water, air and noise. The environmentalists are crying dismentalling of the industrial units on the ground that these pollute the surroundings endangering life of even the neighbourhood.
