It is mentioned in the passage that population problem ………. .

The population problem arises as the result of a high birth rate, together with a fairly high death rate which is now in some parts declining rapidly, as the result of improvements in public health. There are, in consequence, an increasing number of Survivors producing a population growth of 3 percent annually in Turkey whereas this rate is 0.3 percent for England. Between 1900 and 1967, the population of Turkey grew from approximately 9 million to 34 million, resulting in an annual increase now of just under one million. Even an increase of 2 percent per annum in population, can, if unchecked, lead to a doubling of numbers in less than forty years. So long as food supplies can be increased at a commensurate rate, either by farming within the country, or by an expansion of industry and commerce that can pay for imported food, the position is without danger.
