Which of these best describes the reason for the very rapid growth of the human population in more modern times?

A. An increase of Earth's natural resources

B. Improved health care, hygiene, and technology

C. The rise in income

D. The absence of limiting factors

Hello! We can instantly cancel out A as you should already know we’re using natural resources too fast for them to increase. Whilst C is correct, it isn’t the answer you want as inflation is also increasing. D is correct too but again, not the answer you want as it doesn’t prevent babies from infant death. B is the correct answer as improved health care and hygiene allows for a better chance of the baby surviving, more chance of the pregnancy being healthy and more chance of mother surviving the birth.
