Question

why does the government not do more to regulate nonpoint source pollution?
a. nonpoint source pollution is less harmful to the environment, so it does not need to be regulated.
b. point source pollution is more common than nonpoint source pollution, so it is more regulated.
c. nonpoint source pollution is caused solely by animals, which are not possible to regulate.
d. nonpoint source pollution is difficult to regulate, because its source is difficult to track.

please select the best answer from the choices provided

a
b
c
d

Explanation:

• Option A: Nonpoint source pollution (like runoff from farms, urban areas) can be highly harmful, so this is incorrect.
• Option B: Nonpoint source pollution is actually very common (e.g., agricultural runoff, stormwater), and point source is more regulated but not necessarily more common, so this is wrong.
• Option C: Nonpoint source pollution has multiple sources (not just animals, like human activities too) and the "solely by animals" claim is false, so this is incorrect.
• Option D: Nonpoint source pollution comes from diffuse sources (e.g., multiple farms, urban streets), making it hard to track a single source, so regulating it is difficult. This matches the reality of nonpoint source pollution regulation challenges.

Answer:

D. Nonpoint source pollution is difficult to regulate, because its source is difficult to track.
