Recommended: What is the environmental impact of overfishing
For several years now, overfishing has been in the spotlight as one of the most important environmental issues we can actually solve. As time goes on, our oceans are emptying incredibly quickly; over the course of the past few generations, the amount of available fish in the ocean has changed dramatically. This is largely due to the fact that technology has evolved in such a way that it allows for more effective mass fishing. As we develop new techniques to catch more fish, the level of technology begins to overwhelm the number of fish left to take. Even though this extreme and often illegal loss of fish is shocking, this issue is one that can be worked on and perhaps even solved. Short- and long-term solutions range from simply creating and enforcing more restrictions on fishing to ending the fishing of all wild species. The latter example may seem extreme to some, but others see it as the best solution to a problem that could worsen significantly within the next few years. If the fishing of all wild species would be halted, then ecosystems would be given time to rebuild as populations would grow. However, if the oceans were to near absolute depletion, then there would be no turning back; once all the fish are …show more content…
Walter Starck, an important figure in the scientific investigation of coral reefs, claims that “overfishing simply isn’t happening [in Australia]” (Starck). A point consistently being made by those in support of this theory is that fishermen are too restricted by laws and therefore cannot overfish. Starck supports this by asserting that “the greatest environmental threat we face [comes] from environmentalism itself” (Starck). Environmentalists must learn not to exaggerate statistics or draw conclusions from weak data. If overfishing is truly not an issue, then ending the fishing of wild species would be
Overfishing may have some benefits to it, but does it out way the negatives? By fulfilling our demand we can wipe out our whole oceans! Not just the fish, but water mammals too. Sure it can create jobs, but as what cost? It can help bring up our economy, but at the same time it can bring it down with many fish companies closing down due to lack of profit. Fish is a great source of nutrients, but too much can kill you! In other words, fish can be both beneficial and harmful to not only humans, but everyone and everything surrounding fish. There are three things people can do to help with overfishing, the first thing is to be aware of what you are eating. Is the fish on the fear of extinction list? Also asking yourself is the fish you’re about to eat really the fish you intend to eat? Another thing to ask is, was it shipped over seas? If it was it doesn’t benefit anyone, it won’t help the economy or you. Many fish shipped from a long ways creates pollution and may have lost its nutrients value from the long voyage. One last thing to do is if you see a sewer with a sign leading to the ocean, try not to leave trash near it, or better yet don’t litter at all! All the litter left out on streets or near sewers can cause pollution in oceans, lakes, and rivers which is very harmful for marine life. You can still enjoy fish, but not at such a high demand as
Simply, overfishing depletes fish stocks. The consumer demand for fish has risen dramatically over the past decade or so, so much that fisheries are designing new and innovate ways to catch more fish, and at a faster rate to meet consumer demands. What fisheries do not realize, though, is that their removal of fish from the oceans is too great and far too fast for new fish stocks to be made. So, no mating is occurring, leaving the oceans emptier each day. If this rate continues, all fish in the ocean will be almost non-existent. Already, we are experiencing a major decline in fish population: "In 2003, a scientific report estimated that industrial fishing had reduced the number of large ocean fish to just 10 percent of their pre-industrial population. "(par.6).Overfishing brings the main consequence of decrease in the fish population. People rely on fish for survival (in some countries, fish is their only source of food), and they rely on marine life for products (goods like lipstick, petroleum jelly, make-up, etc.)
Countries, fisheries, and consumers all need to share the responsibility for conserving endangered marine life. First, governments should base their policies on scientific factors and should look for better economic incentives to stop fisheries from overfishing. Second, fisheries should use methods that are not so destructive to the fish population. Finally, consumers should avoid buying endangered seafood, even if they have to pay a little more. If these parties recognize that it is worthwhile to conserve marine species, then they must accept this responsibility.
You're planning a vacation to Hawaii and want to do some fishing while here. If you're planning to hop on a charter sport fishing boat or some other commercial offshore excursion, you don't have anything to worry about except for showing up at the dock on time.
Overfishing refers to an act of fishing more than what the population can replace through normal reproduction (WWF, 2016). This was led by international government efforts to increase fishing capacity in the mid-20th century, which then led to the increase in availability and affordability of protein-rich foods. With this, profitable commercial fleets became aggressive, scouring the world’s oceans and developing sophisticated technologies to find and catch their targeted species. Thus, with a wide selection of fish species available at affordable prices, customers soon became used to them (Geographic, 2016).
There are many impacts that fishing and land animal farming have on the ocean, which are detrimental to ocean ecosystems as well as many other aspects of the environment. Overfishing, killing fish at a much quicker rate than the fish can repopulate, is one major problem. Three-fourths of the world’s fisheries are either fully exploited, overexploited, or depleted (Cowspiracy). Researchers have estimated an end of all viable fisheries by 2018 if the current trends of fishing continue (Mason). According to the Monterey Bay Seafood Watch, hundreds of thousands of animals die every year as bycatch, with one of the worst offenders being shrimp fisheries, catching up to six pounds of bycatch per pound of shrimp. Endangered species are also caught, including predators which are important in keeping the balance in ocean ecosystems (Smith). While many organizations such as the Monterey Bay Aquarium Seafood Watch recommend consumers to eat more “sustainable” fish, this will not stop the massive environmental impacts. Sustainable fishing for one does not account for the natural flux in the population of species of fish; what is considered a sustainable amount of fish to harvest one year may deplete the fishery in another year (Smith). Sustainable fish also are becoming even less sustainable as companies that label sustainable fish must find more For example, after Wal-Mart pledged to selling Marine Stewardship
With a coastline of over 202,000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around $5 billion a year, being one of the world’s most valuable. However, the coasts have not been treated with respect; overfishing, over consumption, and wasteful practices have deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries is projected for 2048.
Demand, revenue, cost, and profit are the driving forces behind any economy. This notion is taught to most students in grade school and will carry on through the rest of their lives helping them make the most educated decisions they can. Logically, the greater the demand for something, the greater the profit will be. Whaling used to be a sizable part of the economy, due to the innumerable uses of a whale’s by-products, and consequently, there was a substantial profit margin. Presently, the largest demand for whaling is by Japan, Norway, and Iceland all of whom partake in whaling for either commercial or “research” purposes. However, the demand and revenue from whaling do not outweigh the costs that have tolled on the species. This practice is largely scrutinized by conservationists who believe that commercial whaling is going to bring some species of whales to extinction. The current demand for whaling is incredibly low; however, it is still necessary to continue the ban on commercial whaling.
Overfishing is a harmful practice, that will eventually lead to the collapse of aquatic ecosystems, if it’s not dealt with promptly. Overfishing emerges from the combination of our over consumptive society mixed with the great profits that come from hauling in a good catch. The consumers demand for fish in Japan seems to be at an increasingly high rate due to the enjoyment and cultural values that arise from sushi and other traditional dishes involving seafood. Approximately 23 percent of Japan’s protein intake comes from the ocean, and as a nation consumes 7.5 million tonnes of seafood annually. CITATION
Every year 73 million sharks are slaughtered, statistically that is over 10,000 per hour, imagine if this were to occur to humans (SharkAngers.org). Sharks are tortured as their fins are slashed off and sold for little profit. This brutal process is called sharks finning and it consists of slicing the shark's fin while they are still alive. After this process is completed they are thrown back in the water severely injured they and are faced with a slow death that is pushing them to the brink of extinction. Shark finning is more common than perceived, this barbaric method is gruesome and should be stopped due to its impractically since it has no taste or medical use, the sharks are treated in an inhumane manner and it interferes with the aquatic
Shark finning is something that should be illegal because shark are animals that should not be hurt for no reason. Because sharks are living creatures that under no circumstance should suffer. Shark finning is the process in which you cut off a shark fin in order to sell for a very large profit to make shark fin soup, this wasteful and often cruel practice contradicts all principles of sustainable shark. Shark finning is something cruel and violent, it affects the population of sharks. It’s something that has to stop because sharks didn’t not came to this world to suffer in that way.
Overfishing is a major threat to ocean ecosystems and to our food source. Overfishing is when we capture drastic amounts of fish in a smaller amount of time than fish can reproduce. For centuries we have relied on fishing as a source for food. Over the years we have developed new methods of fishing and have enhanced our equipment to capture vast amounts of fish in a minimum amount of time. We now have industrial fishing companies that provide for our seafood demand.
Overfishing is the most major problem related to oceans, but it is also the most overlooked. Fishing has been going on for thousands of years, and fish have always been seen as a renewable resource, that would replenish itself forever for our benefit. But around the world there is evidence that fish are not recove...
Unless the current situation improves, stocks of all organisms that are currently fished for food are predicted to collapse drastically by 2048 (WWF 2.) Briggs emphasizes that over-fishing “has induced population collapses in many species. So instead of having less than a hundred species at risk, as was the case some 30-40 years ago, there are now a thousand or more
They are a huge part of the world’s diet. In order to have fish available for years to come, regulations must be set in place and followed. These regulations should include an off season for each fish species. While one species can be fished, another has time to repopulate. When the fish are depleted the oceans ecosystems are set off balance.
