As the human population grows, what happens to our natural-resource requirements? a. resources will be depleted b. we will continue to find resources on earth c. more plants will grow due to increased human consumption of herbivores d. the sun will provide less energy per person

The Correct answer is option (A :Resources will be depleted )
