Overfishing is a form of overexploitation where fish stocks are reduced to below acceptable levels. Overfishing can occur in water bodies of any sizes, such as ponds, rivers, lakes or oceans, and can result in depletion of certain resources. By deplete resources is meant using up or consuming supplies. Coastal management is defense against flooding and erosion, and techniques that stop erosion to claim lands. Both hard engineering and soft engineering are types of coastal management strategies. The reason for making use of these strategies is the need for protection of houses and buildings around coastal areas that can possibly be subject to harm by floods and erosion. In various circumstances both overfishing and coastal management …show more content…
They are not long-term solutions and do little to preserve nature and sustainability can be a basic issue. Soft engineering, however, uses techniques that are cheap and low technology and can take care of nature whilst battling against erosion. Hard engineering is most often the less efficient when dealing with flooding and erosion. It often destroys habitats of fish and other wildlife. it can thus be considered to have more disadvantages than advantages. Furthermore, other coastal management strategies can also have varying impacts on the food we rely on. Smoke and pollution released from factories surrounding coastal areas can be hazardous to marine wildlife such as fishes and other such foods which can be considerably relied on by millions. To prevent this from occurring, more effective and worthwhile solutions could be used to prevent erosion, flooding etc. such as soft engineering. Hence, strategies used to defend against possible coast damaging natural disasters are to an extent useful, but can have effects on environment therefore decreasing food sources. Overfishing is a profound problem around the globe whereas coastal management strategies only have some disadvantages and have other options the government can resort to if any problem occurs. Nevertheless, both of these have effects on reliable food sources and other aspects. Without a doubt, overfishing has miscellaneous impacts on
The coastal management strategies are not very effective as gathered from the surveys. On average, the participating surveyees gave the strategies a 4 out of a possible 5. This data were gathered from visitors/neighbourhoods who visit on average frequently. The main concern that would need conventional changes are council clean ups for rubbish track paths, washrooms and toilets, increase and improvement in stores and clubs as well as the immediate removal of pet litter.
Economic activity and our environment have been closely linked since man first discovered the concept of trade. In the language of economics, the environment has itself, become an increasingly “scarce resource1”. Since economics is about managing these scarce resources, it will be a useful tool when considering some of the environmental issues facing our planet. One of the major concerns confronting the environment today is the overfishing of the world’s oceans, depleting some species to near extinction. With continued advances in technological and industrial proficiency, fishing vessels are able to fish across the globe, further exacerbating the effects of overfishing. Because the oceans are considered a shared or common
Clover’s stance on overfishing may seem over dramatic, but Clover’s statement is correct in pointing out that the real danger to the ocean’s wildlife is overfishing. Overfishing is when fish and other sea animal populations are being depleted to the point that sea animals cannot keep up with being fished by reproduction. Fishing massive amounts is degrading the oceans, yet there are both developed and developing countries whose economies rely heavily on fishing.
It has become common for sand dunes to be bulldozed to improve the views to the sea. However this destroys the natural protection of the coast. Human activities such as water transport also can cause problems for coastal areas. The dredging of navigation channels and the discharging of the material in deep water to enable larger ships to travel though water channels removes sediment from the coastal system leaving the area susceptible to erosion and will also interfere with longshore drift which will prevent the coastal beach landforms from being maintained such as the development of a spit. It is likely that a spit will be eroded and start to regress in conditions such as these.
Brighton, Glenelg, The West Beach Boat Ramp, Semaphore and Largs North Beach have all been influenced by hard engineering techniques. As an example, Glenelg was one of the few beaches that had some form of a breakwater along the coast. Breakwaters are notorious for having immediate impacts on the beach, but are ultimately useful in protecting the land that meets the beach. The real question is; “Do the benefits, outweigh the negatives?”. Breakwaters are
Soft engineering is working with nature by using natural materials or allowing nature to take back areas. some examples of this is beach nourishment is the process of dumping or pumping sand from elsewhere onto an eroding shoreline which is to create a new beach or to widen the existing beach,this technique is natural and makes the waves lose power travelling across it,However it dosen’t last very long and It does not stop erosion,it simply gives the erosional forces (usually waves) something else to erode for awhile,another type of soft engineering is managed retreat which is where Areas of the coast are allowed to erode and flood naturally,this makes the land become an marsh,slowing waves and reducing ersoion,however land is lost. Another type of coastal management is hard engineering involves building structures to protect the coast. Some examples of this is a sea wall,which is a wall set up to prevent the sea eroding an area of land,thishelps prevent flooding,however waves bounce off the wall and scour the beach removing
The world of today is very different from the world of yesterday. Overfishing affects the economy and could cause major disruptions to the environment of Canada. However, people can ponder about the importance of the impacts that overfishing could cause in
The erosion of shorelines is a natural process that can have beneficial or adverse impacts on the creation and maintenance of habitats. Sands and gravels eroded from the shores of coastal bays maintain the beach as a natural barrier between the open water and coastal wetlands. Beaches move back and forth onshore, offshore and along shore with changing wave conditions. The finer-grained silts and clays derived from the erosion of shorelines are sorted and carried as far as the waters of wetlands or tidal flats, where benefits are derived from addition of the new material. However, excessively high sediment loads can smother submerged aquatic vegetation beds, cover shellfish beds and tidal flats, fill in riffle
According to a study done by Living Planet Report in 2015, 29% of the world’s fishing stocks are considered overfished and an additional 61% is fully exploited with no possibility to produce more fish. Our environment is currently afflicted by a number of different problems, one of which is overfishing. Overfishing is defined by FishOnline as, “Fishing with a sufficiently high intensity to reduce the breeding stock levels to such an extent that they will no longer support a sufficient quantity of fish for sport or commercial harvest.” The overfishing situation is being exacerbated by non-sustainable and destructive fishing practices and unfair fisheries partnership agreements; while there are currently attempts being made at fixing these problems and their effects on overfishing, nothing has been extremely effective.
In contemporary society, human society is progressing rapidly on various fronts. Nevertheless at the same time, the problem of overfishing is becoming increasingly worrisome and attract extensive attention of the society. In this essay, I will address overfishing and propose some possible causes of this phenomenon which can give contribution to some solutions.
Coastal management responses in dealing with impacts such as erosion and pollution in coastal area is managed by groups, government, and individuals. The individual’s response to the dealing impacts such as erosion and pollution is to start cleaning up after themselves for example picking up rubbish or not littering. Group responses in dealing with impacts such as an erosion and pollution by going out of their way to help the wildlife by cleaning and saving the animals from rubbish or trash and well as notifying and making people aware of the dangerous that the natural flora and fauna that pollution has and how the natural beach can erosion which mean they are rapidly changing in structure and tell them about how dangerous the changing of the
The main causes of overfishing are poor fishery management with a lack of regulation, unrestricted access to the ocean and illegal fishing. During the last few decades the demand for edible seafood globally has skyrocketed and the high demand is causing us to overfish to keep up with the demand. Unfortunately, fisherman are catching more fish than can be naturally reproduced. There are only limited regulations in place, which means that fishing companies are basically fishing when and where they want to with out any oversite. Overfishing causes such serious effects such as the ocean life getting knocked out of balance. Coastal communities rely on the benefits of the fishing for social and economic health. When we overfish it
Overfishing is an enormous issue that needs to be corrected or there will be no more fish to catch in the future. The true definition of overfishing is as defined by the national fisheries act from 1996 overfishing is “a rate or level of fishing mortality that jeopardizes a fishery's capacity to produce maximum sustainable yield (MSY) on a continuing basis(kennedy, 2016)." Some of the facts of overfishing are so shocking they would blow you out of the water, as well as some of the effects overfishing can have on the fisheries. The solutions to overfishing are extremely simple and completely within our power to do.
