🌊 Overfishing: What It Is, Why It Matters, and How We Can Help
What Is Overfishing?
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.
The number of overfished stocks globally has tripled in half a century and today fully one-third of the world's assessed fisheries are currently pushed beyond their biological limits, according to the Food and Agriculture Organization of the United Nations. Overfishing is closely tied to bycatch—the capture of unwanted sea life while fishing for a different species. This, too, is a serious marine threat that causes the needless loss of billions of fish, along with hundreds of thousands of sea turtles and cetaceans.
The damage done by overfishing goes beyond the marine environment. Billions of people rely on fish for protein, and fishing is the principal livelihood for millions of people around the world.
Many people who make a living catching, selling, and buying fish are working to improve how the world manages and conserves ocean resources. WWF works with a cross-section of stakeholders to reform fisheries management globally, focusing on sustainable practices that not only conserve ecosystems, but also sustain livelihoods and ensure food security.

Why Is Overfishing a Problem?
* Ecosystem Imbalance:
Overfishing can impact entire ecosystems. It can change the size of fish remaining, as well as how they reproduce and the speed at which they mature. When too many fish are taken out of the ocean it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals.
* Bycatch Issues:
Overfishing often leads to bycatch—the unintentional capture of non-target species such as dolphins, turtles, and seabirds.
* Species at Risk:
Over one-third of all sharks, rays, and chimaeras are now at risk of extinction due to overfishing.
* Human Impact:
Demand for fish continues to increase around the world, and that means more businesses and jobs are dependent on dwindling stocks. Fish ranks as one of the most highly traded food commodities and fuels a $362 billion global industry. Millions of people in largely developing, coastal communities depend on the fishing industry for their livelihood and half the world’s population relies on fish as a major source of protein. When fish disappear, so do jobs and coastal economies. High demand for seafood continues to drive overexploitation and environmental degradation, exacerbating this circular problem.

What Are Scientists and Conservationists Doing?
* Sustainable Fishing Practices:
Organizations like the WWF work with stakeholders to promote sustainable fishing that conserves ecosystems and supports livelihoods.
* Marine Protected Areas (MPAs):
Initiatives like "Revive Our Ocean" aim to protect 30% of the world's oceans by 2030, helping to restore fish populations and marine biodiversity.
* Improved Fisheries Management:
Implementing catch limits, banning harmful fishing techniques, and closing certain areas to fishing have shown positive results in regions like Iceland and the Northeast U.S.
Questions:
* What is one way scientists are trying to fix the problem of overfishing?
* What does “Revive Our Ocean” hope to achieve?
* Why are marine protected areas important?
