geologists. They have given it the name of 'Glacial Epoch'. The reason for the glacial epoch is assigned as follows: All the creatures of the Earth tend to increase the quantity of carbon-dioxide in the atmosphere, during the various metabolic processes going on in their bodies; also the various industrial operations increase the quantity of carbon-di-oxide. With this increase of carbon-di-oxide in the atmosphere, the rate of loss of heat by the earth from its surface is reduced and the earth grdually warms up so much so that the ice caps on the Poles melt and the resulting flood envelopes the entire earth.
