Q. How people are important to develop the economy and the society?

Ans. The people are important to develop the economy and the society. The people make and use resources and are themselves resources with varying quality. Coal is nothing but a piece of rock, until people were able to invent technology to obtain it and make it ‘resource’. Natural events, like a flood or a tsunami, becomes a ‘disaster’ only when they affect a crowded village or a town.
Hence, population is the pivotal element in social studies. It is the point of reference from which all other elements are observed and from which they derive significance and meaning. ‘Resources’, ‘calamities’ and ‘disasters’ are all meaningful only in relation to human beings. Their numbers, distribution, growth and characteristics or qualities provide the basic background for understanding and appreciating all aspects of the environment.
