A recent report on population trend conducted by the think tank of the Worldwatch Institute
identifies signs of slowing growth in some countries.It says populations in 32 countries-all in
the industrialized world-have stabilized because of declining birthrates.But in a handful of
developing countries where population is slowing, the cause isn’t something to 46 , because
more people are dying.
This trend is called “population fatigue,” and it’s beginning in many of the developing countries that
have experienced 47 birthrates and sharp population growth for several decades.Governments in
these countries are now having trouble dealing with feeding, housing and educating an increasing
number of children, while at the same time confronting the falling water table,deforestation and soil
erosion that rapid population growth brings.In these countries any new threat-infectious disease,
drought or famine-can become a full-blown crisis.AIDS is a case
48.WHO estimates calculate that one-quarter of the adult population of Zimbabwe and Botswana are
infected with the AIDS virus, 49 ,these countries stands to lose at least one-quarter of their labor force
in the next decade from AIDS alone, a situation 50 since the yellow fever swept through Europe in the
14 th century.Social unrest is also increasing in these countries.One example is the 51 conflict between
the Tutsis and the Hutus in Rwanda, where population pressures reduced cropland 52 where it could
no longer feed those who lived on it.Demands on the world fisheries and shared water resources are
likely to spark similar conflicts.Already the waters of the Nile are so heavily used that little
reaches the Mediterranean, so any increase in demand or 53 in allocation will also increase
tensions.
The bottom line is that human population growth is 54 to slow one way or the other.
Developing societies will either recognize problems on the horizon and act to encourage
smaller families-or unchecked births will have their 55 in rising death rates.
