Moreover, numerous unwanted fish and sea animals die unnecessarily in the course of the fishing process annually. Thus, it is worth reiterating that unsustainable fishing is one of the biggest threats to sea animals and its continuation could possibly drive these species to near extinction. Notably, the extinction of sea animals could have a destroying effect on the food security, income, and even livelihood of many people who depend entirely on oceanic resources. Thus, humanity ought to embrace sustainable fishing practices. In addition, shark finning and whale hunting also
Consequently, this is where a massive portion of marine life resides. The corals demise is because of water saturation levels, and most of the marine life around the coral is totally dependent on them. In return, this will have a catastrophic effect on marine ecosystems. The planet cannot possibly recover from all the CO2 emissions. In this chapter, ocean acidification comes to light.
• The ecosystem will be severely impacted as masses of species are wiped out. Impacts of a Volcanic Eruption Economic Impacts • Income earned from agriculture, which is likely to make up a big part of the Island’s export revenue may be cut off as all agriculture (located in Zone A) is likely to be destroyed from the eruption. Income from forestry, fishing and manufacturing industries will also sharply decrease, as these sectors may experience substantial damage. • Income from the tourism sector will temporarily stop. Ash will disrupt airplanes, so Aerial airport will have to be temporarily closed down, and all flights will be cancelled.
With urbanisation and tourism development increasing (Sundseth, Kerstin) it is also contributing to coastal erosion rates. Combining the rates of coastal erosion being increased from urbanisation and tourism development the abandonment of small scale farming practices put pressure on the region's biodiversity (Sundseth, Kerstin). Impacts of coastal erosion include flooding and flood damages, damages from storms, soil erosion (Zachariadis, Theodoros), and degradation of coastal ecosystems and the wetlands. Erosion of the coasts will cause a rise in the sea level and submerge the low lying coastlines (Zachariadis, Theodoros) half a meter rise in the sea-level will expose the population to coastal flooding. Foreseen erosion and flooding is to expected to cause damage to the buildings on the coast or near the coast.
Populations of these animals either increase dramatically or decrease dramatically, e.g. the crabs that would eat these fish in 1992 had their populations increase suddenly, due to the loss of their main predator, whereas shark numbers and other predators of the fish would decrease due to lack of food. As a result, these animals will hunt other fish and decrease the population and etc, resulting in a mass increase and decrease of populations in the ocean. Some major issues surrounding overfishing are environmental sustainability, unemployment and economic loss. The questions that the issue of overfishing poses are ‘do the benefits of overfishing outweigh the disadvantages?’ or ‘how can people change the method of catch in order to provide enough food for people whilst preserving populations?’ National/Local Perspective in Hong
It is also ruining the amazing marine biodiversity that South Africa has. Pollution not only comes from industrial sector such as oil companies, but also from littering and sewage. Plastic pollution is one of the types of pollution that effect the marine environment. It is impossible to give an accurate estimation of the amount of plastic that is being polluted into the ocean. However, in 1975 the global fishing fleet alone dumped approximately 135 400 tons of plastic fishing gear and 23 600 tons of synthetic packaging materials
Off shore dredging of sand and shingle in adjacent areas increases erosion in other areas and significantly affects the ecosystem in the dredging area. Large storms easily degrade beach replenishment inputs, thus increasing costs. £20.000 per cubic meter Managed retreat In areas where Managed retreat is permitted, it retains the natural balance of the coastal system. The eroded material promotes the development of beaches and salt marshes in specified areas. Many people lose their livelihood, for e.g.
Believe it or not, it comes from us littering on the ground. Sun, wind, and water breaks plastics down into microplastic, and moves into the ocean to harm our sea life. Now, there is about 60 times as much plastic as there is plankton. Most animals mistake plastic for plankton. An animal's digestive system can't pass plastic, so it stays in the stomach until they finally approach death.
Here is a list of the aftereffect of some causes of water pollution. From oil: Oil spills comes mostly from the transportation ships, and there are millions of gallons that get thrown it the ocean every year. Oil is threatening marine animals in long term way. It affects their organs badly and ruins their ability to breath. Furthermore it weakens their growth and affect adversely on the fish reproduction.
Sustainable tourism will have a positive impact on the environment, therefore it might include natural beauty, conservation of the environment, habitat for local wildlife etc. However, non sustainable tourism will have negative impacts. More so, based on “BBC And The Tourist Truth”, tourists have parties on the beach. When the tourists are on the beach, they end up loitering, littering and sometimes even death happens. Since the tourists might be intoxicated when they are there celebrating, they will make stupid decisions.
