What is a major consequence of overfishing on marine biodiversity?

Overfishing significantly disrupts food webs and leads to the depletion of fish populations, which are critical to maintaining the balance of marine ecosystems. When fish species are overfished, not only does their population decrease, but this also impacts predators that rely on those fish for food, ultimately affecting the entire food web. Additionally, the removal of key species can allow for the overpopulation of other organisms, further destabilizing the ecosystem. This cascading effect illustrates how interconnected marine biodiversity is, emphasizing the importance of sustainable fishing practices to maintain ecological balance and protect various marine species.
