The impacts of overfishing include destruction of marine ecosystems, negative economic ramifications and the loss of aquatic biodiversity. Over the past 50 years, unsustainable fishing practices have pushed many fish stocks to the brink of collapse. The vast majority of the world's fisheries operate at or beyond their biological limits, causing significant harm to the marine ecology.
Growing evidence suggests that the increased volume of fishing activity seen worldwide is seriously harming the health of the oceans as a whole. The loss of key marine species due to overfishing often has a ripple effect that can be catastrophic for entire ecosystems. Overfishing of large sharks has seen increasing number of rays that have placed greater strain on smaller fish stocks. Large scale fishing operations also do harm by capturing large number of untargeted marine life, including corals, juvenile fish and bottom-feeding organisms.
Overfishing is a global problem, one that has many serious economic, social and environmental ramifications. Fishing is the principle source of income for millions of people around the world. Billions of people rely on fish and seafood as a source of protein. Advances in fishing equipment, industrial fishing operations and the growing trend of utilizing larger vessels have allowed commercial operations to harvest more fish than ever before.
