Select the correct statement about the global carrying capacity for the human population.

a. Estimates of the global carrying capacity for the human population depend on resource use per capita.

b. It is impossible to calculate the global carrying capacity for the human population.

c. The global carrying capacity for the human population is limitless because technological advances allow food supply to keep up with global population growth.

Estimates of the global carrying capacity for the human population depend on resource use per capita.

Explanation:

The carrying capacity may be defined as the maximum population that can be sustained by the environment. For the exponential growth, carrying capacity is infinite.

The logistic growth has some limit for the carrying capacity of the population. The resources determines and limit the carrying capacity. The global carrying capacity can be determined by depending ob the resources used by the population.

Thus, the correct answer is option (a).
