What are the consequences of overfishing on the balance of marine ecosystems?

• Overfishing has no impact on the balance of marine ecosystems.

• Overfishing actually helps to maintain the balance of marine ecosystems.

• Overfishing only affects a small number of fish species and does not disrupt the overall balance of marine ecosystems.

• Overfishing disrupts the balance of marine ecosystems by causing imbalances in predator-prey relationships, depleting fish species, disrupting ecosystem structure and function, and impacting fishing communities.
