Question

the human population has surpassed 8 billion and is continuing to grow. what has been a consequence of increased human population growth?

a. one - wayed deforestation

b. increased violent political conflict

c. decreased spread of diseases

d. decreased biodiversity in ecosystems

Explanation:

To solve this, we analyze each option:

• Option A: Over - warmed deforestation is an incorrect phrasing. The correct term related to population growth and environmental impact is deforestation (not “over - warmed deforestation”), so A is wrong.
• Option B: There is no direct, universal link between population growth and increased violent political conflict. Political conflict has multiple complex causes, so B is incorrect.
• Option C: As the human population grows, the spread of diseases is more likely to increase (due to more human - to - human contact, urbanization, etc.), not decrease. So C is wrong.
• Option D: With a growing human population, there is more demand for resources like land, leading to habitat destruction. This destruction reduces the variety of species in ecosystems, i.e., decreases biodiversity. So D is the correct consequence.

Answer:

D. Decreased Biodiversity in Ecosystems
