The names of the minerals and their products have been used to christen various eras of civilization, such as the Stone Age, the Bronze Age, the Iron Age and the Nuclear Age. The sophisticated world of today is largely the result of the enlarged use of minerals, whether it be as fertilizer for food, coal, petroleum, natural gas and atomic energy as sources of power, or countless other necessities of life, like automobiles, aero planes, ships, modern communications and a host of chemicals which are derived from the use of minerals.

This enormous increase in the number of people is called ‘population explosion.’ Many experts believe it is the greatest danger facing mankind. A doubled population means a greater drain on the world’s limited resources. Increasing in population size, age and distribution is affecting climate by producing more green house gases, either in the form of automobile or in the form of thermal energy to meet increasing electricity demand. A larger global population means a larger demand for everything--most urgently, energy. The world population is growing by 75 million peo...
