Abstract: The human race is faced with an increasing number of resource management and environmental
problems. Population growth, particularly in the developing world, has become a significant part
of these environmental problems. Simply put a major problem of lasting significance facing the
world in this century, may well be the sudden and unprecedented expansions of its population.
Studies have shown that the recent population growth in all regions of the world is the
consequence not of increased birth rates per se, but of unprecedented worldwide decrease in the
death rate especially in developed economies. (Ayeni and Adewale, 1996).
Reasons adduced have been that, since the 20th century human race had begun to declare victory
over famine-related and infant mortality problems and at the same time significant advances in
public health and medicine have been applied. These advances, although felt around the world,
did not happen in the same way in today's richer and poorer nations. Death rates are declining
more in developed countries, basically due to changes in preference for smaller family size
compared to the rather large ones which is still common in less developed countries. (Ayeni and
Adewale, 1996).
The relationship between population growth and economic development has occupied an
important position in demographic studies, since Malthus drew the attention of the world to the
fact that world population was increasing at a geometric rate while the means of subsistence was
increasing at an arithmetic rate and he posited that if this is left unchecked it may lead to an
adverse consequence on the world economy |
