Recommended: Essay on effect of overfishing

Human activity creates many problems to the environment. Depending on the activity, humans harm the environment in different ways, such as pollution, deforestation and wasting water or electricity. Overfishing is another example of a human activity that people don´t give much importance to and it´s actually one of the most dangerous and harmful things to the environment and to ourselves. Overfishing is the activity of collecting great quantities of fish to levels that the ecosystem is unable to sustain itself, so it doesn´t have the possibility to recover properly. Species don´t have enough time to reproduce by themselves. Overfishing is becoming a global disaster that should be taken care of in order to maintain marine life stable. Over the …show more content…

Some fishermen still go fishing to areas that are restricted, and they catch the bigger fish like whales and sharks, to sell their fins or other parts of the body. It took us only 55 years to wipe out 90% of the ocean’s predators causing a disruption of the marine ecosystem . On the other hand, not all the fishers are bad, some respect the law and fish where they are told to and to the amount of fish that they are allowed. However, some people think that catching the bigger fish, instead of the small, is better because that way the small fish have time to recover. That´s a theory, but the problem is that when one starts removing the big species from the sea; that’s when there are less predators than prey, and the ecosystem needs to have more predators to help to keep the balance. The big fish, the bill fish, the groupers, the big things will be gone. It is happening now. If things go unchecked, we'll have a sea full of little horrible things that nobody wants to eat. We might end up with a marine junkyard dominated by plankton . Otherwise, the ecosystem would be a chaos. For example, turtles eat jellyfish, but if the turtles become extinct, then the jellyfish population will rise and there would be a change in the ecosystem. This is why nature needs more predators, to maintain everything under

    Under those circumstances, it is only appropriate to preserve the lives of Sharks and acknowledge their importance to the ecosystem, because without them, the aquatic world may collapse and affect the world on the surface likewise. With the ecosystem gone, the niche of the Sharks are gone too, which lead to depletion of the rest of the marine life. This will cause much economic stress and lead to failure. We must know killing sharks are wrong, and we must stop it.

  • Essay On Canada's Fishing Industry

    1832 Words  | 4 Pages

    Overfishing is defined as a form of overexploitation where fish stocks are brought down to unacceptable levels. In the UN Food and Agriculture Organization’s 2 yearly report (SOFIA), it states how over half of the fish stocks, worldwide, are fully exploited. Other research has shown it only takes 10-15 years of industrial fishing to obliterate a tenth of the intended specie. Overfishing causes a ripple effect that hurts the entire ecosystem. The balance of chain depends largely on the interaction between the predator and the prey. For example, if the larger fish are removed than its prey begins to overpopulate, due to the lack of population control. The balance in the oceans are a urgent problem, around 90% of predatory fish stocks are depleted. The ripples can extend even further to land creatures like

    Due to the demand many packaging for the fish can find its was back to sea, or when fishermen are out at sea they can leave their garbage. Many nets from the boats and gears can also be found in the water, that fish can later see as food, eat it, and die; this ties back to extinction in fish. There is much pollution and decline stocks in fish because it is very hard to regulate the seas. To fulfill the growing demand for seafood, many companies are forced to fish beyond areas that are supposed to be non-fishing zones. This is because there are hardly any laws or restrictions telling them where they can and cannot fish. Sally Driscoll and Tom Warhol report in, ‘Overfishing’, that itt wasn’t until 1956 where we saw our first regulation, the United Nations organized the first UN Convention of the Law of the Sea or the NCLOS which helped promote rights of all countries by establishing boundaries off shore. Meaning that some seafood fished in certain areas of the ocean cannot be sold in certain countries, and in some areas it is illegal to fish unless you have a permit from that country. Economy also helps make it harder to regulate the seas, in ‘Overfishing’ it is explained that Preisdent Barack Obama brought up Antiquities Act of 1906, that let fishermen expand their fishing areas. The United Nations FAO estimates that 25 percent of all fish trapped in nets are labeled unusable or not licensed for fishing by the

  • Analysis of The End of the Line by Rupert Murray

    Rupert Murray’s The End of the Line focuses on the depletion of the oceans fisheries and the devastating effects it has already begun to have on ecosystems and less affluent populations. The film opens with a description of the tribulations of Newfoundland. Once possessing waters so populous with cod that one could “walk across their backs in the water,” improved technology and larger fishing vessels began to deplete the fish stocks. Despite placing a moratorium on fishing in 1992, the fisheries had already been depleted to the point of complete collapse. Similar processes are occurring around the world, as only .6% of the ocean is restricted to fishing vessels. According to the film, much of the ocean’s catch has declined by 90%; the continuation of current trends if continue, stocks will collapse by 2048.

  • The Pros And Cons Of Overfishing

    794 Words  | 2 Pages

    We are also catching to many fish and the fish are not able to sustain their population. There are plenty of fish on the endangered list due to over fishing and some of these fish are surprisingly commonly consumed across the United States. I’ll fill you in on the top ten: Alaskan Halibut, it’s a largest flat fish and it’s found in the North Atlantic. #2 is the Beluga Sturgeon, it’s usually consumed for its fillets and eggs that are known as “true caviar”. #3 is Acadian Redfish. #4 is Orange Rough, #5 is the Winter Skate (usually made into fishmeal or lobster bait). #6 the Bocaccio Rockfish, the most endangered in the West. #7 is the European Eel, when these juveniles are caught out at sea they have not yet spawned. #9 is the Goliath Grouper, their harvesting has been banned. #10 is the Maltese Ray, that is now only found in one area of the world, The Strait of Sicily. Most of these fish are being caught as bycatch, meaning they weren’t the intended target species. Our methods of fishing are a big contributor to this problem and bottom trawling, which is mainly used, is one of the most destructive ways to fish. Bottom trawling uses heavy nets that are dragged across the ocean floor catching everything, letting nothing escape. Simultaneously, this kind of trawling destroys reefs and habitats along the way and It could take decades to repair the damage done by bottom

  • Impacts of the Human Ecological Footprint

    and is existing surely because of humans themselves- overpopulation. “Overpopulation is the problem” and causes other externalities such as pollution, deforestation, and a greater handful of biodiversity losses. In addition, overpopulation causes economic and political factors such as more consumption per person and the reduction of resources that can be provided per person. This contributes to the strain on ecological systems and the economic and population growth. With overpopulation, many resources become finite and an umpteen amount of ecosystems are being destroyed. Overpopulation relates to the impact of humans on pollution. Obviously with more human life, there is more necessity for jobs such as factories that give off fumes, automobiles, and the use for burning fossil fuels. In greater extent, this leads to an environmental factor in that it accumulates chemicals in food chains such as mercury, arsenic, and copper. It can lead to political problems as well, when trying to interact with other countries and stop the problem of global pollution and eventually endin...

  • The Effects of Overfishing on the Restaurant Industry

    1580 Words  | 4 Pages

    To fish or not to fish is a personal choice. The fact that the oceans are being overfished is a growing concern for individuals, organizations, and governments throughout the world. In this paper I want to discuss the effects of overfishing on the restaurant industry, and possible solutions to solve the problem. Fishing is an ongoing source of food for people around the world. In many countries it is a food staple in their everyday diet. In more modern societies eating fish has become a sensual experience, and not just for the wealthy. It hasn't been until population explosions in the last century that the demand for seafood has led to more effective fishing techniques and technologies. Now the demand for popular fish like the salmon, tuna, sea bass, cod and hoki, which is the key fish in McDonalds filet o' fish, is diving wild populations to dangerously low levels. The methods used to catch the amount of fish demanded by the industry do not leave sustainable populations in the wild. In an attempt to preserve the fish population, governments have set limits on the minimum size that may be harvested and how many of each may be taken. Boundaries have been set up saying which areas can be fished and which ones should be left alone. A number of smaller fisheries have gone out of business because of the limits imposed by the government. This leads to even less fish being harvested and brought to market. Therefore the amount and varieties of fish at markets are smaller and can cause shortages for wholesalers and restaurants. Some restaurants will no longer have the variety on their menus that they used to enjoy. If a restaurant thrives on its seafood menu they may be unable to cope with the shortages and will go out of business. In the ...

  • Water Pollution: Plastic in the Ocean

    1110 Words  | 3 Pages

    Water pollution has had devastating effects on the environment, which include irreversible effects to the oceans ecosystem. People often underestimate the importance of the ocean. They don’t realize how much damage pollution has caused to the ocean and the thousand of creatures that inhabit it. Earth is a huge place, but resources are actually very limited and will not last forever; unless there is a balance. We must protect the resources we have in order for them to last into the next generation. Every time we throw away a plastic bottle, drive our cars, and even burn those millions of fossil fuels to operate all those huge factories, there is a chance it will pollute the ocean and eventually effect the way we live. There should be stricter laws regulating human pollution, in order to protect our oceans ecosystem.

  • Due To Overfishing

    ...makes the issue of overfishing one that needs immediate attention. It seems that government action is the only means of solving overfishing. Although the fishing industry will be initially resistant to increased regulations, in the end the entire industry can end up better off. Although this is a global issue, it is more relevant in the Mediterranean than many other regions. If issues aren’t resolved now consumers of the Mediterranean diet will undoubtedly face increased food prices and therefore other cascading negative repercussions. A utilitarian approach is the only means of achieving true progress. Bearing the initial burden of a decrease in the supply of fish will not only save the oceans’ fish from devastation but also produce lasting benefits for both consumers and suppliers of fish. If serious initiative is not taken soon, the damage will be irreversible.

    Jacques-Yves Cousteau once said, “Overconsumption and overpopulation underlie every environmental problem we face today” (“Population,” Internet). With the current statistics, Jacques could not be more accurate. Every second, 4.2 people are born and 1.8 people die, which would be a net gain of 2.4 people per second (“Population,” Internet). At this steady rate, the environmental health is spiraling downwards, and it is safe to assume humans are responsible for this. As the population increases, harmful effects on the land, water, and air also do.

  • What are our responsibilities toward the environment?

    1810 Words  | 4 Pages

    We all belong to the same world and all of us have the same responsibilities towards the world and its environment. This fact might be hard to digest, but if we continue to pollute the Earth at the current rate, all of the world’s ocean waters will become one-hundred-thirty percent acidic. This means that the ocean will be unable to sustain most of its marine life and only a few creatures will be able to survive in the water. A big population of people think that they do not or have few responsibilities towards the environment. People think that the governor of a country should take steps to help the environment. They leave it to scientists since they have the technology to prevent pollution, or that is what most people think. There are more responsibilities to the world each individual has than most of realize. The amount of negligence and ignorance of humans towards the Earth is taking a heavy toll.
