In the context of the human population, what is a likely consequence of continued human population growth if resource consumption patterns remain similar?

• A. A long-term decrease in total resource use because larger populations inherently consume fewer resources per person
• B. An overall increase in global biodiversity because more land will be protected as human populations expand
• C. A reduction in atmospheric $C_0{2}_2$ concentrations due to increased urbanization
• D. Increased demand for food, water, and energy leading to greater pressure on ecosystems and natural resources

Answer: (D)

Verified step by step guidance

1. Understand that human population growth leads to more individuals requiring resources such as food, water, and energy.
2. Recognize that if resource consumption patterns remain similar, each additional person will consume roughly the same amount of resources as current individuals.
3. Analyze how increased resource demand can strain ecosystems by depleting natural resources and causing habitat loss or degradation.
4. Consider the impact on biodiversity, noting that increased human activity often reduces biodiversity due to habitat destruction and pollution.
5. Conclude that continued population growth with unchanged consumption patterns results in greater pressure on ecosystems and natural resources, rather than a decrease in resource use or an increase in biodiversity.
