Question 6 • Science 7 B (M12 25/26 S2)

Which statement describes the current theory about the relationship between the human population and mass extinction?

Answer
A
The human population is increasing, so the likelihood of a mass extinction is also increasing.
B
The human population is increasing, so the likelihood of a mass extinction is decreasing.
C
The human population is decreasing, so the likelihood of a mass extinction is also decreasing.
D
The human population is decreasing, so the likelihood of a mass extinction is increasing.

Explanation

Human population growth increases demand for land, food, and other resources, which can destroy habitats and put more pressure on other species. These effects raise the risk of widespread species losses, so the current theory is that as the human population increases, the likelihood of a mass extinction also increases. The correct choice is “The human population is increasing, so the likelihood of a mass extinction is also increasing.”
