The word pollution has been derived from the Latin word pollution, which means to make dirty. Pollution is the process of making the environment land water and air dirty by adding harmful substances to it. Pollution causes imbalance in the environment. Environmental pollution is a serious problem of industrialised societies. The industrial development and the Green Revolution have adversely affected the environment. People have converted the life supporting system of the entire living world into their own resources and have vastly disturbed the natural ecological balance.

Environment pollution is defined as the unfavourable alteration of our surroundings. It is a by-product of man’s activities which directly or indirectly are responsible for the changes in environment. Industrialisation has led to urbanisation. The migration of rural population to cities in search of work has created an unhealthy environment. It has led to overcrowding and establishment of slum areas. Towns and cities are full of smoke, fumes, dirt, dust, rubbish, gases, foul smell and noise.

Public education and awareness of the relationship between climate change and human health is a key to deal with these problems more effectively.

We should be united and work together to eliminate such issues from our environment.
