Answer:
b. According to Malthusian Theory, the remaining population would rapidly grow to consume the newly available excess resources rather than maintain the high standard of living that Thanos was trying to create.
Step-by-step explanation:
Economists believe that the growing population of humans on earth is a source of concern as there are inadequate resources to satisfy the teeming population. However, reducing the population of the world by half would not address the issue.
According to the Malthusian theory, there are positive checks such as famine and death that help to regulate a population. Reducing the population of people in the world by half will cause pressure on the environment, resulting in an increase in the population, so that the population is commensurate with the available resources.
