Provided that sharks have not been fished out of certain areas it is reasonable to assume that their disappearance would be a result of the destruction of a suitable habitat. The fact that shark species are so diverse and inhabit every ocean on the planet makes them key players essential to the ocean environment. Yet despite their importance in the marine food-chain they remain a low conservation priority. For all their evolutionary success and apparent menace, sharks are incredibly fragile, unable to withstand the increased pressures forced on them by the voracious world fishing industries. This is partly due to the fact that sharks are slow growing animals that mature late, live long, and have a low reproduction
Certain species have a huge impact to an ecosystem, but even the smallest fish could have the biggest impact. Overfishing occurs when more fish are caught than the population can replace through natural reproduction (overfishing). The results not only affect the balance of life in the oceans, but could also affect the coastal areas that depend on fish for their way of life. For centuries, our seas and oceans seem to be considered a limitless food supply. But that is not the case, increasing fishing efforts over the last fifty years as well as unjustifiable fishing practices are pushing many fish stocks to the point of extinction.
Dispersants cause the oil to break up into smaller droplets, which become miscible in water. However, these dispersants may result in more ecological harm than good. The chemicals contain nonbiodegradable toxins that can kill fish and migrate great distances. Dispersants also are blamed for the massive oil plumes several hundreds of feet underwater, harmful to all aquatic life, especially fish larvae and filter feeders. Moreover, because of the large volume of oil that has been spilled, the amount of dispersant required and the amount of oil dispersed simply suppresses the problem, rather than solving
2008). Therefore, plenty and diversity of fish decreases (Dudley and Platania 2007). Some fishes evolve for living in habitat change. Because water flow changes in the river affect their breeding and growing (Nilsson and Berggren 2000), but few species can adapt from a flowing water system to a still water system (Huntingford and Torricelli 1993, McCartney 2009), including salmonids (family Salmonidae) (Gharbi et al. 2006).
As people have to be hired to clean up, and people not wanting to go to dirty beaches. Cost money to people working at the beach. This problem doesn’t just occur in the Persian Gulf, it occurs world wide. A study from the university of Georgia, February 3rd 2015, claims that about 8 million metric tons of plastic trash enters the ocean every year. Pollution in the Persian gulf is negatively impacting marine life, as oils spills occur, and ocean mining is at it’s peak, but most importantly sewage dumping.
The population of the largest and most significant vertebrate plants feeds, including sea turtles, dugongs, have been severely decimated by the impacts of humans on the reef. The loss of these vital animals has and will more severely disturb the coral reef food web in a significant manner, although the specific impacts are not clear
A state that heavily participates in these cleanups is Florida. The Florida Department of Environmental Protection hosts many reef cleanups in various counties and even offer giveaways for participating. The only downfall is that you have to be a certified diver in order to participate in the cleanup. I think that the practice that will have the greatest impact on the problem would be for the human population to focus on making changes that will help decrease global warming affects. If we began to lower the amount of energy we use, the amount of waste we produce, and the amount of pollution we allow to go into the oceans the algae would not be forced to leave the coral due to the conditions of the water.
As demand for metals and other materials grow in economy, countries turn to the ocean for collecting these materials that may occur more readily in the ocean floor. As informed by conserve-energy-future.com, the deepest parts of the ocean are being affected the worst by the mining; and acidity is increased due to the materials polluting the water: “For example, copper is a major source of pollutant in the ocean and can interfere with the life cycles of numerous marine organisms and life.”. They also state that as the acidity increases, corrosion of man-made objects is inevitable, leading to more pollution due to degrading material and increased oil spills. This then leaves another overcast of deadly substances to hinder the lives of creatures that must endure the circumstances placed by human
Ocean acidification is killing off the oyster population, which is also affecting the jobs in Washington. Initially, ocean acidification is when acidic gases are emitted into the air and absorbed into the ocean. According to the video Ocean Acidification by NOAA, ¼ of all the carbon dioxide release into the air is absorbed into the oceans. Some major contributors to carbon emissions are automobile gas and factory emissions. This is a problem in the Pacific Northwest because acid sinks to the bottom, but Pacific winds bring acidic water up from the bottom near the shore by the shellfish.
As humans expand they are producing more waste and need a place for it to go. In some countries, people just pump the waste into the water, as a result it is harming the manatees. The waste that humans are pumping into the ocean is causing toxic algae which the manatee eats and it makes the sick or could kill them. The waste from humans hurts the manatee also by
Growing up, I often found inspiration snorkeling in the Florida Keys. Each trip, I entered an ever-changing resilient ecosystem of vibrant, vivacious sea life. However, in recent years, nonnative lionfish have invaded the entire East Coast devastating our coral reefs. Because they have no natural predators in the Atlantic Ocean, lionfish have almost completely depleted our oceans of juvenile fish, creating a major food shortage for native fish. If no action is taken, the future of our coral reefs over the next 50 years looks alarmingly grim
