Question

(iii) The world population has grown very rapidly. Why?​

Answer 1

Answer:

Hope this helps you.

Explanation:

The world population has grown very rapidly because the death rate has gone down as a result of the growth of food supplies and the improvement of medical facilities.

Also, unlike the death rate, the birth rate has remained quite high.

The birth rate and the death rate are two factors that influence population change.

The birth rate is the number of live births per 1000 people while the death rate is the number of deaths per 1000 people.

Thus, the birth and death rates affect the balance of population.

Answer 2

The main reason for the growth of world population is that with better food supplies and medicine, deaths were reducing, while the number of births still remained fairly high.
