Why is fishing bad for the environment?
Fishing may disrupt food webs by targeting specific, in-demand species. … It may also cause the increase of prey species when the target fishes are predator species, such as salmon and tuna. Overfishing and pollution of the oceans also affect their carbon storage ability and thus contribute to the climate crisis.
