Question

which change is a direct result of continued population growth in the united states?
a an increase in the size of wildlife habitat areas
b an increase in the spending on highway networks
c a decrease in the use of energy - efficient building materials
d a decrease in the use of alternative energy sources

Explanation:

Population growth leads to more people needing transportation infrastructure. An increase in spending on highway networks is a direct result as more roads are needed to accommodate the growing population. An increase in wildlife habitat areas (A) is unlikely as population growth often leads to habitat encroachment. A decrease in the use of energy - efficient building materials (C) and alternative energy sources (D) is not a direct result; in fact, with more people, there might be more of a push for sustainable options in some cases.

Answer:

B. An increase in the spending on highway networks
