Final answer:
The rapid growth of the world's population in the last 70 years is due to scientific advances in medicine, agriculture, sanitation and hygiene, and transportation, making 'E. All of the above' the correct answer.
Step-by-step explanation:
The rapid growth of the world's population in the last 70 years is due, in part, to scientific advances in medicine, agriculture, sanitation and hygiene, and transportation. Therefore, the correct answer to the question is E. All of the above.
When analyzing the factors that have strongly contributed to the rapid population growth, we can identify the following significant factors:
- Sanitation and Hygiene: Systems for providing clean water and proper disposal of human waste have drastically reduced the transmission of diseases.
- Medicine: The development of immunizations and antibiotics has played a crucial role in controlling infectious diseases, which previously limited population growth.
- Agriculture: Advances in agricultural technology, including mechanization and use of fertilizers, have increased food production and supported larger populations.
- Public Health Behavior: Changes in behavior, such as reduced smoking rates and precautions against sexually transmitted diseases, have improved overall health and longevity.
These factors combined have led to a significant decrease in death rates and an increase in life expectancy, which in turn contributes to population growth.
