Question

what might happen to a shared fishing lake if no limits are set on the number of fish that can be caught?
the fish population will grow larger and faster.
the overall water quality will start to improve.
the lake will become more popular for fishing.
the fish population may decline significantly.

Explanation:

If there are no limits on the number of fish caught from a shared lake, overfishing is likely to occur. Overfishing means more fish are removed from the population than can be naturally replenished through reproduction, so the fish population will likely decline significantly. The other options are incorrect: no limits on fishing won't cause the population to grow faster (option A), won't improve water quality (option B), and while the lake might be popular initially, overfishing would likely reduce its popularity for fishing over time rather than make it more popular (option C).

Answer:

D. The fish population may decline significantly.
