What is the impact of fishing on marine life?


overfishing can have an adverse effect on marine biodiversity. it wreaks havoc and destroy the environment and marine ecology and completely disrupt the food chain. For example, herring is a vital prey species for the cod. Therefore, when herring are overfished the cod population suffers as well.
