The modern civilisation depends upon products—natural as well as man made. With the help of technology, resources are being utilised on a large scale. The exhaustible resources will not last long. 80% of the fossil fuels will be finished in one century With the exhaustion of resources, the civilisation will come to an end. Therefore conservation of resources is necessary. A balance should be maintained between population growth and utilisation of resources so that the continuity of modern civilisation goes on. The natural resources are common heritage. We have to share these with future generations.
