Intro: You know what is absolutely delicious? Sushi. I mean who doesn’t like Sushi? But did you know that the yummy blue fin tuna that we eat in our Sushi is nearly extinct? But oh well, who really cares? There’s plenty of fish in the sea, right? Um… maybe not.
CNN Opening Theme:
Hey guys, Mahek here for CNN news. Now oceans are massive, like they cover 71% of the Earth and 99% of Earths living space. So there is a lot of space in Oceans. Could you imagine that humans could even impact or actually even change the ocean life?
Yet over the past few decades, fish populations have been decreasing year after year. YES, WE ARE OVERFISHING OUR SEAS. Overfishing is when more fish are caught than the population can replace through natural reproduction. For most of human history, overfishing occurred through small tiny boats of fishing fleets. But in the 1900s new technology changed fishing techniques. Bigger and advanced nets and radar allowed fishing to be more quick, efficient and of more quantity. All of a sudden, fishing became a huge commercial resource. So for a while, things were going great, enough food source and lots of money.
In spite of that, the world got a wake up call around 1990. After 500 years, one of the oldest fisheries suddenly

Trawling is one of the most popular methods of fishing. It is extremely helpful in catching lots of fish, but it is also extremely helpful in causing lots of damage. One study from the Proceedings Of The National Academy Of Sciences, states that it “removes a layer of sediment, which over time leaves the fishing area completely infertile.” I’m not trying to find fault on fisherman here. In fact, the UN states that “Fishing is central to the livelihood and food security of 200 million people.” And many people living in coastal communities depend on fish as a primary source of protein and
I believe that killer whales held hostage, should be retired and allowed to live freely because of the unnatural punishment and torture that Seaworld is putting them through. There has been 151 cases of aggression between Orcas and their trainers. Also 100% of male Orcas in captivity have a collapsed fin compared to the 0.01% in the wild. In fact, every single mother within captivity has had its calf taken away around age 2. This isn't going to stop without your help. So, here are some more facts to convince you to SAS ( strike against Seaworld. )
In this entertaining, search into global fish hatcheries, New York Times writer Paul Greenberg investigates our historical connection with the ever changing ocean and the wild fish within it. In the beginning of the book Paul is telling his childhood fishing stories to his friends, that night Paul discovers that that four fish dominate the world’s seafood markets in which are salmon, tuna, cod, and bass. He tries to figure out why this is and the only logical answer he could come up with is that four epochal shifts caused theses wild fish population to diminish. History shows that four epochal shifts happen within fifteen years causing certain fish species populations to diminish. He discovers for each of the four fish why this happened to
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
Overfishing is a major problem in economy today. The practices of fishing too much or too often result in a decrease of the fish population. Constant removal of fish from the oceans (fishing) accounts for both adult and baby fish. With the consistent decrease in adult fish, mating becomes more difficult or even impossible, resulting in an overall lack of fish in the oceans. Pepijn Koster defines overfishing as, "Overfishing can be defined in a number of ways. However, everything comes down to one simple point: Catching too much fish for the system to support leads to an overall degradation to the system. Overfishing is a non-sustainable use of the oceans." (par.1). When fish stocks cannot be replenished faster than they are being depleted, a reduction in fish population occurs, which is what is referred to as overfishing.
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.
Ocean Pollution is a serious issue in today's global politics. The delicate balance of Earth's ecosystem is put in jeopardy when the ocean is not clean. Problem evolving from ocean pollution directly harm marine life and indirectly affect human health and the Earth's many valuable resources. Ocean Pollution is a Broad term that encpompasses any and all foregin matter that directly or indirectly makes its way into the ocean. This includes everything from the extreme: oil spills, Toxic Waste dumping and industrial dumping-- to the small scael: human activities and basic carelessness. Because the oceans and all other water bodies are invariably, somehow connected, and because they account for 3/4 of the Earth's surface, they are an ideal method of transportation for pollution, allowing the rapid spread of seemingly far away toxins into a river near you! It is increasingly important that we educate ourselves as to what, exactly, ocean pollution is, so that we can identify the causes at their source and take action in small and large ways, and hopefully, prevent this terrible form of pollution from getting any worse than it is today.
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.
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 ...
Many of the methods used in commercial fishing are very destructive to the aquatic systems. Industrial ocean trawlers scrape the bottom of the water, often dragging up the seafloor with them. This destroys the habitat and kills many of the bottom dwelling organisms that are vulnerable to these practices. There is also a large amount of marine animals that are unintentionally caught by the large nets. These animals are considered bycatch, having no value to fishermen and are usually killed. These large fishing vessels also add a significant amount of pollution to the water. Fishing vessels cause oil spills as well as discharging chemical elements and wastes into the water. The thousands of of trawlers that pass through Japanese waters create large quantities of water pollution that can devastate aquatic life by changing the chemical composition of the water and affecting all the organisms that inhabit these
industrial fisherman catch too many fish at one time and it affects not only the
So lets start by taking a look at where we a get a major percentage of our food today. The oceans are being over fished and fish populations are dwindling more rapidly than ever. Many people don’t understand the various consequences of this horrible dilemma which we face daily. The reasoning is that killing off the fish doesn’t only effect fish but everything dependent on fish, such as humans, sharks, mammals and other types of fish. You can further understand this if you took a look at a food chain. Every creature is a link you remove one the chain is weak, and susceptible not to function properly.
Going fishing Are we being greedy by taking more than we need,when we go fishing?Why is overfishing a problem,and how can we solve it?These days people are overfishing by taking more than they need,and they're doing it very often which are not letting the fish reproduce. The question that we are trying to solve today is what happens to commonly used resources in society?My hypothesis is that a commonly used resource in society is that they well start to disappear and become rare if we don't allow them to produce again. A solution for overfishing is for a government to enforce the amount of fish caught by persons. Most fishing areas are unprotected and are in dangerous areas.
In addition, the weight and width of a bottom trawl can destroy large areas of seafloor habitats that give marine species food and shelter. Such habitat destructions can leave the marine ecosystem permanently damaged,” (Destructive Fishing). Although we only intend to can a few fish, we end up catching too much fish, as well as other things, such as rocks and seaweed, that we didn’t need to tear from the ocean. National Geographic states, “Faced with the collapse of large-fish populations, commercial fleets are going deeper in the ocean and father down the food chain for viable catches. This so-called "fishing down" is triggering a chain reaction that is upsetting the ancient and delicate balance of the sea's biologic system,” (Overfishing).
While humans like to think of themselves as the smartest species on the planet, there is still so much to be discovered about the ocean and the creatures living inside of
