Because birth rates have begun to fall Earth's population will stabilize somewhere around 9 billion by 2300.

Answer: Option D

Explanation:

During the modern age there was a rapid growth in the population. Those times there were adequate food supply and better hygiene. Now the birth rate has progressively come down. As women were educated of family planning and techniques on child care the modern women have lowered birth rates.

But the decrease in birth rate is just a mirage as it is equal when compared in urbanization and there is decline in the death rate too. The fact is that the birth rate is actually not deteriorating but it is definite pace.
