This large number of fisherman leads to the second cause, illegal fishing. You cant fast forward to a century-old coral forest. When we talk about commercial fishing, we often talk about stocks and catch size; we talk about how many fish there are for us to take and put on plates. When large predators are removed from the ecosystems they help to regulate, creatures further down the food chain are often negatively impacted. Fish ranks as one of the most highly traded food commodities and fuels a $362 billion global industry. With the fish population decreasing, fishing jobs will become scarcer causing people to lose jobs and having to find other work. 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.

From climate change and plastics, to deep sea mining and overfishing the threats facing our oceans are growing and becoming more urgent by the day. Overfishing is closely tied to bycatch the capture of unwanted sea life while fishing for a different species. As these populations decrease, these species of fish also face other issues. Even though bycatch is used to provide restaurants with fish, overfishing also impacts humans and the job market. The rise of industrial fishing has led to the harvesting of wildlife at rates too high for species to replace themselves.

About a third of global stocks are overfishedand the overall proportion of fish stocks at sustainable levels has continued to decline. When a fish population declines, algae can grow unchecked and eventually smother corals. Fish then become underpopulated in the overfished area and that throws off the balance of the surrounding ecosystem. Approximately 80% of fish stocks are overexploited. Why high seas fishing isn't just destructiveit's unprofitable. Here's how. And that would mean the climate will benefit too.

The time shift started as a way to maximize limited daylight hours, but its benefits are debatable. Understanding the vast amount of disruption and harm that overfishing creates is the first step toward putting feasible solutions into action. Subsidies lead to overcapacity of fishing vessels and skew production costs so that fishing operations can continue when they would otherwise be unsuccessful. An increased use of aquaculture, the farming of seafood, would also help. As National Geographic reported at the time, harmful subsidies are those that fund practices that would not otherwise be profitable, such as for industrial trawlers fuel costs.
