Answer:
Explanation:
Human beings evolved under conditions of high mortality due to famines, accidents, illnesses, infections and
war and therefore the relatively high fertility rates were essential for species survival. In spite of the relatively
high fertility rates it took all the time from evolution of mankind to the middle of the 19th century for the global
population to reach one billion. The twentieth century witnessed an unprecedented rapid improvement in
health care technologies and access to health care all over the world; as a result there was a steep fall in the
mortality and steep increase in longevity. The population realized these changes and took steps to reduce
their fertility but the decline in fertility was not so steep. As a result the global population has undergone a
fourfold increase in a hundred years and has reached 6 billions
