state any three causes of population explosion
Answers
Answer:
Increase in the birth rate- Due to lack of control on delivery and unawareness of people the birth rate is increasing rapidly. In addition, the gap between death and birth has gone way wider than what we can think of. Furthermore, the birth rate has increased many folds in comparison to the death rate.
The life expectancy growth- Earlier the life expectancy of people was around 55-60 years. But due to better and improved medical facilities, we are now able to increase the life expectancy of people. Now the average age of a person increased to 70-75 years.
A decrease in infant mortality rate- Mortality rate refers to the number of death of infants below the age of 6 months. Due to science and technology, we are able to minimize this rate and now only a few cases of death are known per thousand death.
