Answer:
D. Depleted natural resources
Step-by-step explanation:
If the human population on Earth continues to grow, depletion of natural resources is a very likely consequence.
Especially at the rapid rate that humans consume natural resources, continued population growth would eventually deplete them.
Fossil fuels are an example of natural resources that will eventually deplete, as humans use immense amounts of things like coal and natural gas.
Answer choices A, B, and C are incorrect because they would be consequences of decreased human population growth.
So, the correct answer is D. Depleted natural resources.
