Fishing is one of the most significant drivers of declines in ocean wildlife populations. While fishing is not inherently bad for the ocean, it is when humans catch fish faster than stocks can replenish, a practice called overfishing. Overfishing decreases the number of species living in the marine ecosystem. How does overfishing affect sustainability




Overfishing causes algal blooms



Overfishing eliminates non-native species



Overfishing alters the food chain





Overfishing introduces invasive species.



Answer :

From the information provided, it is clear that "Overfishing alters the food chain" (Option C) See explanation below.

How does overfishing alter the food chain?

When too many fish are removed from the ocean, an imbalance is created that can damage the food chain and lead to the extinction of other essential marine life, particularly sensitive species such as sea turtles and corals.

A reduction in the number of people in one link of a food chain can have an impact on prey-predator relationships across the ecosystem.

How to prevent overfishing?

To prevent overfishing, the government in alliance with Marine ecosystem monitoring agencies establish fishing quotas to fishermen. Although it is not a perfect system, this helps to reduce the amount of overfishing.
