WORLD POPULATION
Projections issued in 2000 showed the world population (31) increase from 6.1 billion in 2000, to 7.9 billion in 2050. “High” and “low” projections for 2025 are 8.4 billion and 7.5 billion respectively. The average world birth rate is projected to (32) decline from the 1990 level of 26 per 1,000 to 22 per 1,000 at the .end of the century and to 17.6 per 1,000 in 2025 (corresponding to a fall in TFH from 3.3 in 1990 to 2.1 in 2025). Because of the (33) expanding share of the population at high-mortality ages, the average world death Tate is expected to decline only (34) slightly; from 9 (per 1,000) in 1990 to 8.4 in 2025. Average world (35) life expectancy, however, is projected to rise from 65 years in 1990 to 71.3 years in 2025. Wide (36) variations in population growth will undoubtedly persist. In the developed world, population growth will continue to be very low and in some nations will (37) even decline. Western Europe as a whole is projected to have a declining population after 2000. U.S. Census Bureau projections, assuming middle fertility and (38) mortality levels, show U.S. (39) population increasing from 250 million in’ 1990 to 349 million in 2025 and 420 million in 2050. Thereafter, (40) growth would be virtually zero.
B. Read the passage, then choose the correct answers.
No one knows the limits of population that the earth can support. 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.
