Recommended: Effects of pollution on marine ecosystems
I will be presenting the first affirmative of today’s debate. The United Stated federal government should substantially increase its non-military exploration and/or development of the Earth’s oceans. Before I go further I would like to define the key terms of today’s debate. The United States federal government is defined as the system of government in the Constitution which is based on the separation of powers among three branches: the executive, the legislative and the judicial. The ocean is defined as the whole body of salt water that covers nearly three fourths of the surface of the earth. To increase means to become larger in amount or number. Nonmilitary means not belonging to, characteristic of, or involving the armed forces. Exploration …show more content…
means the act of traveling to a place or searching a place in order to learn about it. Development means the process of developing or being developed. Substantial means the “essential” part of something, important, and not imaginary. Solving overfishing by banning destructive fishing practices will be substantial to life. These definitions come from the Oxford Advanced Learner’s Dictionary, Merriam-Webster, The Macmillan Dictionary, The Cambridge Dictionary, and Baylor Briefs. I strongly believe that we should increase exploration and/or development of our oceans.
Why? Our oceans cover nearly three fourths of the surface of our earth. According to overfishing.org, eighty percent of all life on earth is in the ocean, and us humans are threatening and driving them to extinction by overfishing. What is overfishing? Overfishing is defined as “To fish (a body of water) to such a degree as to upset the ecological balance or cause depletion of living creatures.” (Merriam Webster Dictionary) Recent studies from the Environmental Defense Fund reveal a bleak truth: Overfishing is depleting our oceans of sea life around the world. 87% of the world’s assessed fish stocks are at their breaking point, classified as overexploited or fully exploited. 1 out of 2 fish stocks in the U.S. are either overfished or at risk of being overfished. Moreover, 100 million sharks are killed each year. Carl Safina, world-renowned author of books such as Song for the Blue Ocean, once said, “If you're overfishing at the top of the food chain, and acidifying the ocean at the bottom, you're creating a squeeze that could conceivably collapse the whole system.” Overfishing is classified as the most dangerous threat our oceans are facing today. Worldwide, about 90% of fish stocks are gone forever. In 1990 our oceans contained at least six times more fish than they do today. Collapsing fish stocks create large ecological dead zones in our
oceans. We are ruining our lives ourselves by overfishing. This leads me to believe that we need to increase exploration of our oceans. Ocean scientist estimate that only five percent of our oceans have been explored. For the past three decades, NOAA (which stands for the National Oceanic and Atmospheric Administration), has pursued a course of ocean regulation and management without ever developing a comprehensive exploration program. Thus, our science lacks a fundamental understanding of enormous ocean regions and important ocean systems. According to a press conference held by authors Steven Gaines and Christopher Costello, Michael Arbuckle of the World Bank, Brett Jenks from RARE, an internationally known environment conservation society, and Amanda Leland, who is the Environmental Defense Fund's Vice President for Oceans, giving fishermen a concrete stake in the fishery means that they are invested in protecting it. When overfishing ends, the amount the entire fleet can catch increases, as does fishermen’s share of the catch. Economic interest and conservation interest go hand in hand and fishermen lead the way. Amanda Leland also said, “This study shows that recovering the world’s fisheries is absolutely critical, and, by working with fishermen, completely achievable.” Moreover, the Greenpeace International organization says in their 2013 Oceans in the Balance: The Crisis Facing Our Waters report, “Every second breath we take comes from the oceans. Billions of people rely on our oceans for their food and for employment. In return, we are plundering the oceans of fish, choking them with pollution and altering them forever with the impacts of human-induced climate change. Once seen as boundless, the world’s oceans are finite and the marine life they hold can indeed be exhausted. Soon our oceans will be unable to recover.” Additionally, the United Nations have taken action as well. In their third United Nations Global Biodiversity Outlook, they warned, “Unless radical and creative action is taken quickly, our oceans will collapse.” Moreover, the White House Council on Environmental Quality also emphasized the importance of the oceans. They said, “The importance of ocean, coastal, and Great Lakes ecosystems cannot be overstated; simply put, we need them to survive. It is clear that these invaluable and life-sustaining assets are vulnerable to human activities and, at the same time, human communities are rendered more vulnerable when these resources are degraded.” This absolutely proves that our world NEEDS to increase exploration of our earth’s oceans, and that it is completely feasible as well. Therefore, my plan is, “The Department of Interior will ban all commercial fishing in Marine Protected Areas and establish guidelines and enforce regulations on the recreational use of Marine Protected Areas.” Thank you and I now stand down for questioning.
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.)
Everybody has one thing in the world that they feel strongly about. Weather if it is a stuffed animal, person, or a job. We all praise something. I believe that we need to stop whaling. Every day whale after whale die. Why? Just because people want their meat and to make oil and some money. We need to find a way to stop these terrible Pandemic. There has to be another way to make money and oil than killing this marvelous animal. If this was happening to you what would you want to do to stop this?
Salmon are in huge demand all over the world. In 2014, over 146,000 were caught statewide. Even though it may seem as though catching all of these salmon will cause them to go endangered, they still thrive. There are many ways that humans also contribute to keeping the salmon population high. We raise them ourselves and also help out the ones in the wild. One of the ways we do this is by creating fish ladders. Fish ladders are like stairs underwater that fish like salmon can use to get over an obstacle that is in the way. Salmon can travel up to 1,000 miles and can not be stopped by different things such as water falls for dams. These ladders have helped them out tremendously.
In the last 30 years since the lionfish first appeared in the Atlantic Ocean, they have become a destructive nuisance. The lionfish species which are native to the Pacific Rim and Indian Oceans are now invading the Atlantic and Caribbean Oceans, eating any fish that can fit into it's mouth. Scientists don’t believe the invasion will ever be completely eradicated, however if the problem is recognized there are steps that can be taken to try and contain this invasion at a manageable level. Through education, fishing or hunting of the species and by teaching other species to eat the lionfish, there is hope humans can gain control over these invasive creatures.
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
Jack: Yes, Overfishing is a global disaster. Over three quarters of the world is covered by oceans and are full of fish. You see, lots of people love to fish, but some people take it a bit over the top. Fishermen fish almost everyday but some of them fish for hours and hours catching a ton of fish. Millions of people rely on the ocean every day and other people in other parts of the world that need the fish in the water to eat and survive on.
Oceans flourish through increased productivity, still, potential exhaustion though extinction is casting out a possible “tragedy of commons”, hook, line, and sinker. From thriving to potential empty oceans; the environmental and human impact on our oceans remains extensive, with over one-half of the world’s fish populations being exploited, according to the United Nations Food and Agriculture Organization (FAO). Additionally, the expected depletion of our ocean species according to scientists within a 2006 scientific journal, predict the total collapse of all oceanic species by the year 2048 (Withgott & Laposata, 2012). Oceanic productivity may have potential toward recovery by assigning no-fish zones and marine reserves. The capability to shift the tides toward replenishing our oceans should also combine monitoring and protecting its productivity by encouraging oceanic reef systems and decreasing over-fishing.
Overfishing has become a huge problem for today’s oceans. A total of almost 80% of the world's fisheries are fully- to over-exploited, depleted, or in a state of collapse. Overfishing is exactly what it seems like it would be. The act of “fishing too much” is when fishermen are catching fish so fast and with a high occurrence that the fish are not able to reproduce quickly enough to regrow the population in the respective bodies of water. This problem has gotten progressively worse as we humans are now relying on fish as a food resource even more then the past and the equipment and techniques used by the fishermen have made it easier and more efficiently for more fish than ever to be caught. Even though overfishing
How important is the ocean? Plants that grow in the ocean produce half the oxygen all of the world’s population needs to survive (The Nature Conservancy, 2014). The Carbon dioxide the body releases is also absorbed by the ocean’s waters (The Nature Conservancy, 2014). Medicine that is used to fight cancer and cure disease is formulated from ingredients from the ocean (The Nature Conservancy, 2014). Not only does the ocean keep the people of the world healthy but it accounts for 128 billion dollars of the GDP, keeping the economy healthy also (The Nature Conservancy, 2014). The ocean is a big part of what makes Earth a place where human beings can live and flourish. It is surprising that despite the oceans great importance people are still destroying it, through a series of events that starts with a simple trip to a local sushi restaurant. Eating tuna causes destruction of the ocean because of the elimination of species and it’s effects on the food chain.
Overfishing takes place when fish and other marine creatures are fished more quickly and than they can reproduce and sustain their populations. To put it simply, taking too many fish out of the seas before new fish can be born to replace the ones that were caught by us. If current trend keeps continueing we might not have a future where all our kids cant enjoy the great fishes in this world. Extracting too many fish from the ocaen can hurt the food web. What im saying is that people need to fucking care about the land or we can leave in trash in the furture. I believe that around 2040 that there would be alot of fish on the edge of being extinted.
Approximately 70% of marine production is used directly for human food, and marine fisheries play an important role in food security. Part of the world fish production is reduced to fishmeal and oil used for raising cattle, poultry and pigs and is therefore used as human food indirectly. The ability to catch fish is reflected by the growth of global fish landings, which peaked in the late 1980s at around 90 million tonnes per year. Global fisheries are living on borrowed time. The generally expressed objective of fishery management: to catch the maximum yield that a population can sustain. However, most stocks are being removed faster than they can reproduce and so are actually being mined rather than harvested. Coastal ecosystems produce more than 90% of the food provided by marine ecosystems. Coral reefs alone produce 10-12% of the fish caught in tropical countries and 20-25% of the fish caught by developing nations. Making overfishing one of the main issues regarding marine protection. Giant ships are now using...
Well, this is a hard question to answer because those two countries have been hunting whales for a long time, but honestly I do not agree with the Norwegian and Japanese position to hunt whales. I would be agree if whales would be the only source of food they have in their territories, but hunting whales is not really necessary because there are more ways to feed themselves. The whaling ban can affect their cultures and traditions from ancestors, but they have to understand that we have to conserve the existence of whales to avoid their endangered in a future.
There are many ways that we can stop overfishing. One way is to have more protected marine areas. We can do this by setting up more protective areas in the oceans which can help reduce the effects of overfishing on some of the world’s most incredible reefs and marine structures
To stop overfishing would take the collective power of governments all over the world. Fortunately, the actions taken against overfishing have steadily been increasing but currently only about 1.5% of oceans are considered protected from fishing. The reason it is so hard to fix the problem is that “overfishing has impacted over 85% of the world’s fish resources” and the world has gotten so used to the amount of fish it consumes, it does not want to stop (Kukreja). Not to mention countries such as China ignore laws and regulation having to do with fishing making them one of the leading countries for overfishing. The loss of predators in marine environments has already taken hold as planet wide temperatures are increasing, and coral reefs and ecosystems are dying. If we do not do something before key species are wiped out completely there will be almost no hope for restoring the marine ecosystem. Overfishing negatively effects nearly everything around it, from the air we breathe to coral reefs of the
Flyfishing for trout isn’t a complicated, difficult sport. A close look reveals that a successful flyfisherman has mastered several basic abilities: casting smoothly and accurately, knowing how to select a fly that trout will eat on a given day, presenting a fly in a manner that is enticing to trout, and fighting and landing hooked fish. It’s all about problem solving, one step at a time. The following 10 pointers will help you execute those key elements of flyfishing, whether you’ve just gotten your first fly rod or you’re an experienced angler who wants to become even better
