Question
What could be the reasons behind enormous increase in human population?
✓
Answer
Human population has increased enormously in last century due to increased natality and reduced mortality.
Due to advances in medical sciences, vaccinations and better life expectancy mortality rate has been considerably reduced. With the exception of Covid 19 Pandemic, all the mortalities due to epidemics were controlled due to modern medical facilities.
Due to better food production and advances in agriculture methods, people are not starving anymore. This has considerably reduced the deaths due to starvations.
However, natality rate has not been reduced especially in developing countries. Lack of family planning measures, ignorance, illiteracy and traditional thinking about birth of male child, all such factors have caused tremendous increase in the human population.
