Question

question 7 of 10 assume that the biocapacity of earth does not change and that human population growth continues to increase. how will people’s ecological footprints need to change in order to most effectively sustain our population? a. the average ecological footprint will need to increase. b. the average ecological footprint will need to decrease. c. the average ecological footprint will need to stay steady. d. the average ecological footprint will need to become zero.

Explanation:

Biocapacity (Earth's resource - providing ability) is constant, but population grows. Ecological footprint is resource use per person. To sustain more people with fixed biocapacity, per - person resource use (average ecological footprint) must decrease. A is wrong (more use can't sustain), C is wrong (steady use won't account for more people), D is impossible (zero footprint means no resource use, which is not feasible for survival).

Answer:

B. The average ecological footprint will need to decrease.
