throughout history population growth has proceeded at a relatively slow pace,from approximately 250 million people in A.D.1 to 500 MILLION PEOPLE BY 1650.wITHIN THE past 300 years,however,ournmubers have invreased dramatically,douubing in ever_shortning cycles,so that by 1930 world population stood at 2 billion and a brief 48 years later at over 4 billion.if population growth vontinues at its present rate,it willl put enomous pressure on world food supplies, making it difficult,if not impossible,to avoid hunger and starvation on a massive scale.Despite all the triumphs of atrclture in the twentieth century,population growth goes way ahead of the gains in food production.Hundreds of millions of people in Africa,Asia,and South America lead lives dominated by hunger and malnutition,and we are adding 75 million people to the world each year.TO provide adequate food for the world's people by the year 2000,according to one expert,the production of grains must be doubled,animal prducts quadrupled,and fruits and vergetables tripled,the probability of accomplishing such goals is not high,given the uncertainties of weather and the difficulty of raising sufficient capital to finance such efforts. |
