Question

what is the main source of water?​

Answer 1

Answer:

Human resources must be considered both from the angle of assets as well as the liabilities connected with the attainment of economic development. For the attainment of economic development, proper utilisation of both natural as well as human resources is very much essential.

Proper utilisation of natural endowments and the level of production of national wealth depend very much on the extent and efficiency of human resources.

But too much population will again eat up all the fruits of development. Thus from the point of view of economic welfare, it is quite essential to study human resources in detail. It should be equally stressed that human beings are the vital instrument of production and at the same time, fruits of all economic activities are rested on the betterment of conditions of living of human beings.

Thus in view of its importance, it is quite essential to know both in quantitative and qualitative terms, the size, rate of growth, the composition, distribution and all other demographic features of population of India.
