Answer 2

Answer:

Population explosion can be used to refer to the sudden, large increase in the size of a population. There is an increase in the population every day, leading to population explosion. Two of the major reasons are as follows:

• Increase in the birth rate and the longevity

• Decrease in the death rate

In the last 50 years, the death rate has decreased evidently. Decrease in the death rate and increase in the birth rate can be attributed to the various measures that have been adapted such as diseases-control, measures taken to create awareness and spreading knowledge of importance of reproductive health, measures taken to introduce sex-education topics at school level, better medical facilities, ensuring food supply and medical assistance during emergency times and so on. These reasons have also led to an increase in the longevity of people.
