Answer 1

Three main reasons for the sharp rise in the human population in the world :

1. Better healthcare for all age groups:
   - The advancement in healthcare for both infants and older people has drastically increased the natality rate and decreased the mortality rate respectively.
   - Hence the difference between natality and mortality widens thus leading to an increase in population.
2. Reduction in infant mortality rate:
   - Better nutrition for pregnant women and better healthcare for newborn babies has resulted in a reduction in infant mortality rate as the chances of babies surviving after birth increased.
3. Availability of food:
   - Advancement in the agricultural sector by the introduction of various capital techniques has increased the production of food to a great extent.
