Question

Which one has mainly controlled human population density?

• A. Industry
• B. Natural resources
• C. Climate
• D. Communication

Answer 1

The correct option is B Natural resources

Natural resources are resources that people can use which comes from nature. People do not make natural resources but obtain from the nature such as air, water, wood, oil, wind energy, iron, and coal. Higher the population, more the demand on resources. Thus, the growth of human population will result in the decrease of natural resources. More the number of human will demand more of land, water, etc. In other words, availability of natural resources is a limiting factor of increase of human population. They are inversely proportional.

So, the correct answer is option B.
