Question

question 9 of 10 human population growth rates are increasing. assuming that the biocapacity of earth does not change, what will need to happen to the average person’s ecological footprint to best sustain our population? a. it will need to become zero. b. it will need to stay the same. c. it will need to decrease. d. it will need to increase.

Explanation:

Ecological footprint is the resource use by an individual. With population growth and constant biocapacity (Earth's resource - providing ability), to sustain, total resource use (population × average footprint) must not exceed biocapacity. If population increases, average footprint needs to decrease to keep total use within limits. A (zero) is impossible for survival. B (same) would increase total use. D (increase) worsens the situation. So C is correct.

Answer:

C. It will need to decrease.
