Overfishing significantly impacts ocean ecosystems by depleting fish populations and disrupting food webs. When fish are harvested at unsustainable rates, it can lead to the collapse of local fish stocks, altering predator-prey relationships and affecting other marine species. This disruption can result in biodiversity loss and habitat degradation. Furthermore, overfishing can threaten the livelihoods of communities that depend on fishing for their economic stability. Implementing sustainable fishing practices is essential to preserve marine ecosystems and maintain global fisheries.
