give reason why the world population is not stable
Answers
Answer: The world population is growing now because the birth rate exceeds the death rate. In the future either a decrease in the birth rate, or an increase in the death rate, or a combination of the two will stop population growth.
Explanation: Projections of population reaching more than one generation into the future are highly speculative: Thus, the United Nations Department of Economic and Social Affairs report of 2004 projected the world population to peak at 9.22 billion in 2075 and then stabilise at a value close to 9 billion. A reduction over time in a region's population can be caused by sudden adverse events such as outbursts of infectious disease, famine, and war or by long-term trends, for example sub-replacement fertility, persistently low birth rates, high mortality rates, and continued emigration.
