Which of the following is NOT one of the main factors responsible for the rapid rise in the human population?

Question

BlackTom AI · Accepted Answer

To tackle this question, I’ll evaluate each option in terms of its contribution to the rapid rise in the human population.
Option a: The Green Revolution. This refers to increased agricultural yields through improved crops and farming practices, which directly boosted food supply and supported population growth, making it a main factor.
Option b: The discovery of antibiotics. The availability of antibiotics reduced death from infectious diseases, significantly lowering mortality and contributing to population expansion, so this is a main factor.
Option c: The use of high density energy (in the form of hydrocarbons). Access to abundant energy, especially fossil fuels, powered agriculture, transportation, and industry, enabling a larger population to be sustained, which makes this a main factor.
Option d: The development of cities. While urbanization accompanies population growth, it is not a primary driver of population increase itself; cities arise as a consequence of growth and economic organization rather than causing rapid population expansion. This makes it the correct choice for NOT being a main factor.
Option e: The application of the Haber-Bosch process (producing synthetic nitrogen fertilizer for agriculture). This massively increased agricultural output by providing essential nutrients for crops, a well-established main factor in supporting larger populations.
In summary, all options except d describe mechanisms that directly enabled more people to be sustained or increased mortality reduction, whereas the development of cities is more a pattern that results from growth rather than a primary driver of the rapid rise in population.
