3. Overfishing. The global consumption of fish is outpacing natural production, posing a significant threat to marine ecosystems. Commercially valuable species are fished at enormous quantities to the point where populations of fish species are dangerously low.
Fishing is one of the most significant drivers of declines in ocean wildlife populations. Catching fish is not inherently bad for the ocean, except for when vessels catch fish faster than stocks can replenish, something called overfishing.
