Ocean overfishing is defined by taking wildlife from the sea at rates too high for fished species to replace themselves. Have you ever imagined what the ocean would be like if it was empty? You probably haven’t given it much thought, have you? While watching the documentary called, “Mission Blue” on Netflix, Carl Safina states, “The sad fact of it is that the Ocean could be empty and still look the same. It's a very hard thing to convey what's happening, how it will affect you personally. And so as the Ocean is being emptied, and as the Ocean is dying, the surface looks the same, the waves look the same.” The ocean is dying and the truth is most of don’t even realize it! Since the beginning of man oceans have been a symbol of beauty and the …show more content…
Marine life is very important and we need to work on fixing this problem and finding solutions for it. Is it possible that every time we overfish, it hurts us? From the 11th century onwards, overuse has led to the destruction of local and regional ecosystems. Evidence shows that humans have been depleting the wealth of the oceans throughout history. It has been said that Europeans started over-exploiting freshwater fish at least 1,000 years ago. One of the discoveries in the New World was when the British found cod along the Grand Banks of Newfoundland. Cod, at that time were virtually non-existent along the coast of England due to over-fishing. In “A brief history of overfishing” by Greenpeace they state, “We have now reached a point in time where business cannot continue going on "as usual". With almost no technological and geographical limits left by the beginning of the 21st century, the fisheries crises has turned into a global threat to the oceans” (paragraph 3). You’d think …show more content…
It seems like such a small problem at first, but when you look closer it turns out to be a bigger problem than expected. In “Overfishing” by Pristine Seas it states, “But by 1989, when about 90 million tons (metric tons) of catch were taken from the ocean, the industry had hit its high-water mark, and yields have declined or stagnated ever since” (paragraph 6). It is now 2015 and it’ll keep declining as time moves forward. One solution to this problem is genetic modification which means any alteration of genetic material, as in agriculture, to make them capable of producing new substances or performing new functions. Now, genetic modification does have its many issues, but it can end up being a big help. Rothamsted Research in Hertfordshire is working on this right now. One challenge with this is that they need to find a non-fish source of the omega-3 oil needed to sustain farmed populations. This article from the Independent titled, “GM crops could help to solve the problem of over-fishing” states, “If successful, the Rothamsted crop offers a way out of one of the tighter bottlenecks in modern food production. Nor does the potential end there. Given that fish oils are directly beneficial
First of all, the article Too Many Fishermen enlightens the readers about the dangers and risks of overfishing. For example, on lines 12 through 15 it states, “Overfishing depletes fish stocks by taking fish at a rate faster than they can replace themselves. Many fish are harvested before they are even mature enough to reproduce. As a result, marine species are dying at an alarming rate.” The author used this evidence to better show how real and harmful the situation is. This is used by the author to help support the idea that humans have a negative impact on the ocean and helps to spread the word easier.
Fish and other animals are being genetically modified which means that they could be unhealthy or could lead to huge toxicity cases furthermore they could start to genetically modify other animals like cows. This is an unreasonable decision because the harms are inadequate which could mean there could be much harm like toxicity and allergic reactions which means that GMO is not safe and should not be in the market till all the advantages and disadvantages are figured out.
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 species. Overfishing causes a ripple effect that hurts the entire ecosystem. The balance of the chain depends largely on the interaction between the predator and the prey.
Earth's oceans make up over 75% of the Earth as a whole. With that being said, it is vital to understand the significance on the contents of the oceans. Since fish and marine products make up a large portion of our diet, fishing practices need to be properly managed. In this essay, overfishing will be defined, its consequences will be revealed, and plans for proper fish distribution will be executed.
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
Imagine a lush underwater place. Beautiful structures colorful animals and places that would never have been thought of before. In reality that's not what it really looks like, really the ocean is a desolate place that is barren like a desert. Many marine species have been lost by as much as 49%.(seeker) A big part of that reason is because of coral bleaching which causes as stated above a decline in species that depend on the coral as there home. Coral bleaching is a serious problem that could cause problems for everyone if we don’t fix it.
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).
Overcapacity of vessels in the water is one main reason for overfishing. It is said that there are enough vessels in the water to fish 4 planet earths—crazy, right?. There is so many powerful boats out there with intense competition for limited fish. Technological advances such as sonar detection leaving the fish no hope for escape. These vessels have become so efficient that they have
In the real world, all this comes down to two serious problems. We are losing species as well as entire ecosystems. As a result, the overall ecological unity of our oceans is under stress and at risk of collapse. The affects the fish that is at the bottom of the food chain to overpopulate. If the fish that are at the bottom of the food chain overpopulate, the food they eat will become scarce This means that the fish that is at the bottom of the food chain will become extinct or endangered because of the lack of food. Another effect of overfishing that is fishing down the food chain. That will affect the species that are at the top of the food chain because the species that are at the bottom of the food is chain are important preys to them. That’s why fishers should be aware, that if they catch too much of the fish that is at the top of the food chain it will affect the whole system of predators and preys. If the fishers catch too much of fish, that’s at the top of the food chain, it would also affect the balance of predators and
As highlighted in both greenpeace.org and National Geographics overfishing is a direct result of industrialization and the increase of commercial fishing. What is happening is that in the commercial fishing industry they are fishing at fast pace in order to quickly make a profit at the expense of longterm sustainability of the oceans ecostistem. This will ultimatly lead to a lack of fish, destruction of many oceanic wildlife homes and the extinction of many species of desired fish if not corrected quickly.
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
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...
overfishing is a real problem and needs to be fixed. Some people may ask how
Genetically modified foods could cross-pollinate with other plants and create an entirely new species. In addition, there is the danger of biotech-resistant weeds and insects evolving. GMO’s have the potential to alter ecosystems in significant ways. Companies are currently engineering salmon, tilapia, carp, and other fish to promote faster growth or to provide resistance to certain diseases. Aquaculture farms are located in oceans and other bodies of water and the fish escape the nets regularly, ecologists worry that genetically modified fish could breed with natural fish.
Did you know that more than 90 percent of all organisms that have ever lived on Earth are extinct? According to Pandey, the author of Humans Pushing Marine Life toward ‘Major Extinction’, nearly 10,000 species go extinct each year, and this rate is estimated to be 1,000 times higher than the natural extinction rate (1). Human beings are causing irreversible damage to the oceans and their wildlife, which is being led by two major reasons: Commercial fishing or over-fishing, which damaged the marine environment and caused a loss in the marine life diversity, and pollution, which is a primary way of the extinction causes that drastically modifies the marine life habitat. As a result of the commercial fishing and pollution, many of the marine species will start disappearing of the oceans. 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 (10).”
