Thomas Malthus, an English economist, developed a theory that became widely accepted in the nineteenth century. He suggested that because world population tended to increase more rapidly than the food supply, a continual strain was exerted upon available resources. Malthus cited wars, famines, epidemics, and other diseases as the usual limitations of population growth. With recent advances in science and technology, including improved agricultural methods and great strides in medicine, some of the limiting factors in population growth have been lessened, with obvious results. International organizations have put forward several recommendations to alleviate the problem of overpopulation, including an increase in food production, general economic development in target areas, and a decrease in birth rate. Most experts agree that it will be necessary to combine all three recommendations in an effort to affect a lasting solution. 2. The dramatic growth of the world's population in the twentieth century was on a scale without parallel in human history. Most of this growth had occurred since 1950 and was known as the population 'explosion'. Between 1950 and 1980 the world population increased from 2.5 to over 4 billion, and by the end of the twenty century the figure had risen to about 6.6 billion. Growth of this size cannot continue indefinitely. Recent forecasts suggest that the total population will level out at between 10 and 15 billion in the mid twenty first century. Already there are encouraging signs that the rate of increase in many less developed countries is beginning to slow down. - scale: quy mo - without parallel: khong co gi sanh duoc .
