In recent year population growth has become one of the most crucial human problems. The number of people in the world is growing at a staggering rate. It took the entire period of our history as a planet until 1850 to attain a population of one billion. The second billion took an additional 75 years. In early sixties the number was 3.5 billion. If the trend continues twice as many people will be living earth in the 2000 as they were in 1968. The world population will shoot up to 7 billion. Today every tick of the clock adds 2.2 people to the population. The rhythm would increase to 2.7 by 1980, to 3.3 by 1996 and 4.4 by 2000 if the same rate continues. The picture is not very rosy to conceive. If the crisis has not yet arrived it is just round the corner (Mehta-1982).
