The industrialized world we live in today is overdosing our oceans in nutrients like nitrogen, carbon, iron, and phosphorus compounds. These compounds come out of smokestacks, washes into the oceans from fertilized cropland, and seep out of septic tanks and sewer pipes. This process causes the tiny marine plants to run riot, then die and drift to the bottom of the ocean. Afterwards the bacteria takes over, and in a process of breaking down the plant matter, sucks all the oxygen out of the water, leaving little, or none for other marine life, so the only marine life that can survive are the primitive organisms that evolved long ago in an ocean with no oxygen, and so they require little to survive (jacquet). If we do not take action all modern day marine life will die off and primitive organisms will once again, rule our oceans.
Industrialization is a major contributor to the more evolved marine organisms dying off. From over fishing to over dosing our oceans in nutrients, it seems we’re trying to kill off all evolved marine life in our seas.
Overfishing is a huge factor we must consider. Over fishing occurs when marine species are caught faster than they can reproduce. It seems like now days it’s happening more and more
to a variety of species. According to Pavan Sukdev a United Nations Environment Programmer “we are in the situation where forty years down the line we, effectively, are out of fish”. This is not good news for the one in five people that depend on fish as the primary source of protein (Food and Agriculture Organization). Overfishing has become such a threat to our oceans that, the save our oceans foundation has named it number one out of the five biggest threats to our oceans.

...erfishing, to over dosing are oceans in nutrients we are killing more evolved
species of marine life. With these species out of the way for competing for food and shelter, the more primitive organisms, that are not as affected by things like overfishing and too many nutrients in our ocean, are left with an abundance of resources, which is causing them to abundance in population. We have seen this across the globe and the evidence is irrefutable, and the condition of our oceans will only continue to get worse, if we don’t take action!

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
Overfishing can lead to sea creatures becoming extinct. This can ruin an entire food chain and continues
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.)
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.
Somehow our oceans maintain the balance between being some of the most powerful forces on the earth, and the most easily disturbed masses on the planet. There are so many things that could go wrong within the countless cycles, and the delicate processes that stabalize nature and sustain the biosphere; and people are continually interfering with these cycles. Ocean acidification is one of the most obvious results of human interference upon nature. “Pollution is nothing but the resources we are not harvesting. We allow them to disperse because we've been ignorant of their value.” ("R. Buckminster Fuller, in Memoriam").
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
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
Animal extinction is an issue that is occurring all over the globe. It is also something that has occurred since the beginning of time. However, it used to be natural process that would take a long time, now with human involvement the extinction of certain species is accelerating. Most species become extinct because of habitat destruction, introduction of non-native organisms, and direct killing. The marine species are no exception to the human acceleration in extinction either by the general benefit received by them, but only those classified as more valuable that other species get a voice to classify them as endangered while the other are extinct.
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
overfishing is a real problem and needs to be fixed. Some people may ask how
The attempts of overfishing aren’t working and people are not listening to the problem. Pollution, climate change and habitat loss are problems too. “One problem is a decline in fish habitats. Also, the oceans' tropical reefs have decreased by half and could all be lost by the year 2050. Much of this is due to warmer waters and acidification. Over 25% of ocean marine life lives on coral reefs and roughly 850 million people directly benefit from them, the loss of coral reefs could be catastrophic, according to the report. A second problem is pollution. There is 250,000 metric tons of plastic in the oceans. Plastic harms smaller fish that bigger fish rely on for survival and may also harm larger fish and mammals who become tangled or trapped, resulting in suffocation. Related to pollution is climate change, which is responsible for changing the oceans more rapidly than at any other point in recorded history. A slight rise in temperature will change ocean currents and increase acidity levels. A slight temperature increase will also disrupt the ocean's food chain. Species will alter their migratory patterns in search of cooler water, which will only further unbalance the world's oceans.” (CNN, Gray) This shows that people need to stop littering and polluting the
Going to a Japanese restaurant for Bluefin tuna sushi or a fish and chip restaurant for Atlantic cod is a luxury that many people enjoy. However, these consumers may not know that they are eating endangered species. Do consumers put too much trust in the government and fisheries? Should they pay more attention to the source of their food? This essay will address the issue of where the responsibility of conserving ocean-life lies. The responsible parties are national governments, fisheries, and consumers. If these parties have an interest in the future of sea-life, the fishing industry, and seafood, then they all need to take responsibility for protecting endangered species from overfishing.
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
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).”
