The growth of population during the
past few centuries is no proof that population will continue to grow straight
upward toward infinity and doom. On the contrary, demographic history offers
evidence that population growth has not been at all constant. According to
paleo-ecologist Edward Deevey, the past million years show three momentous
changes. The first, a rapid increase in population around one million B. C.,
followed the innovations of tool-making and tool-using. But when the new power
from the use of tools had been exploited, the rate of world population growth
fell and became almost stable. The next rapid jump in population
started perhaps 10,000 years ago, when men began to keep herds, plow and plant
the earth. Once again when initial productivity gains had been absorbed, the
rate of population growth abated. These two episodes suggest
tha A. One. B. Two. C. Three. D. None.

On the contrary, demographic history offers evidence that population growth has not been at all constant.

C., followed the innovations of tool-making and tool-using. But when the new power from the use of tools had been exploited, the rate of world population growth fell and became almost stable. The next rapid jump in population started perhaps 10,000 years ago, when men began to keep herds, plow and plant the earth. Once again when initial productivity gains had been absorbed, the rate of population growth abated. These two episodes suggest that the third great change, the present rapid growth, which began in the West between 250 and 350 years ago, may also slow down when A. Human population expands at a straight upward trend. B. Population growth has shown ups and downs in demographic history. C. Population growth can not be regarded as a social failure. D. Increase in population is related to productivity.
