Question

3.2.5 quiz: impact of humans on ecosystems
question 9 of 10
a small town wants to begin a conservation program to protect its natural resources. how might the town best begin designing a solution to conserve its freshwater sources?
a. figure out which sectors have the highest water usage, and then develop specific solutions to decrease water in those sectors.
b. randomly test solutions in one sector to see which solution has an impact on water use, and then apply that solution to all other sectors.
c. implement sustainable practices on power plants after the freshwater supply runs out.
d. focus mainly on the homes of individuals, which collectively use more water than the other sectors.

Explanation:

This approach is targeted and efficient. By identifying high - usage sectors first, resources can be focused on the areas that will have the most significant impact on freshwater conservation. Random testing (B) is inefficient, waiting for water supply to run out (C) is reactive and risky, and focusing only on homes (D) ignores other potentially high - usage sectors.

Answer:

A. Figure out which sectors have the highest water usage, and then develop specific solutions to decrease water in those sectors.
