Lars Gustafson 11/4/15 GEOG 304 Research Paper: Shark Finning With an alarming one in four shark species endangered across the globe, we have come to a breaking point where our oceans ecosystems could suffer permanent damage if the practice of shark finning in the oceans off of Eastern Asia continues as shark population’s plummet. According to www.stopsharkfinning.net, tens of millions of sharks are killed every single year just for the fins that are the main ingredient in shark fin soup. Shark fins are harvested to feed the growing demand for shark fin soup that is an Asian delicacy food. When the sharks are finned they are usually thrown back into the water and left to drown slowly. Sharks rely on their fins to swim and allow water to
It’s also very sad as well because entire ecosystem is going down with the recent crazy population of the mussels. Zebra mussels started to show up in the Hudson river in may 1991. Scientists estimated there size in numbers and it turned out to be a whopping 500 billion. That is a lot of mussels in one river. This might sound crazy but if you put all of the zebra mussels on one side of the river it would outweigh all of the other animals in the ecosystem.
The reading states that a huge marine animal known as Steller`s sea cow had been became extinct, and provides three reasons of support. However, the professor explains that no one know why this creation became extinct, and refutes each of the author`s reasons. Firstly, the passage claims that the extinction of sea cows were because of over hunting that made from native Siberian. Although, the professor refutes this by saying these creations were massive in weight, moreover native Siberian were not big population. Therefore they did not have to catch a lot of them in order to feed them.
For many it’s a first pet, a gift from family, something you won as a prize at a carnival, but for Canadian residents the familiar orange goldfish everyone knows and loves is becoming a serious problem. Some flush them in a hurry because they no longer want to take care of them, others commit them to a porcelain vortex because they believe their beloved fish has passed, and the Canadian Government is issuing a warning now to citizens of Canada to stop flushing their fish. Just a few goldfish with the potential to disrupt an entire ecosystem Goldfish are entering the ecosystem the way that a lot of invasive species end up in an environment they don’t belong, Humans are putting them there. Human interference is one of the leading causes of the beginning of over population of invading alien species. In this case many of the fish are going down drains, and ending up in Canada’s lakes and rivers.
Overfishing has drastically changed marine environments in many ways, species have gone extinct, and environments have depleted. If overfishing continues to occur our society won’t have the marine life that we are very dependent on. Ever since the 11th century, overfishing has been a problem. Many fishermen have overused local and regional ecosystems, which led to destruction.This resulted in a major reduction of stocks in fish and marine mammals. After destroying one ecosystem, the fishermen would
They are actually close to extinction. This is because people are going deep-ocean trawling. This means that a net is being drug along the ocean floor, sadly the blobfish gets scooped up as well, and even though it is often tossed back into the ocean, by then it is already too late. In 2006, nature conservationists from all over the world gathered to propose the restriction of bottom trawling on the high seas, but were unable to reach an agreement, leaving the fate of the helpless blobfish greatly uncertain, especially since the deep trawling fishing fleets of Australia and New Zealand are very active, and the blobfish isn’t found anywhere else in the world. The blobfish has become famous because it has been called “cosmetically challenged”.
They take things and just believe it without knowing the truth or doing any research to support the claim. Today in the United States there are approximately three different Sea Worlds located in San Diego, San Francisco, Orlando, and San Antonio. Over the past years, Sea World has begun to lose a lot of revenue and money because of drastic drops in people attending Sea World. According to Michael Calia in his article “Sea World hit by Bad Press; Stock Off 33%” this drop is mainly because of the recent media debate about the treatment of the captive Orcas in Sea World. Publicists and media stated that the treatment of these animals was very bad and they deserved to be set free into the
The Europeans came to America for many reasons but the biggest was wealth. One thing they brought with them was smallpox which had disastrous effects because the Cherokee’s immune system was never introduced to the disease. The medicine men were incapable of finding a cure so they went to the traditional purification treatment, sitting in sweat houses before wading in the chilling streams. This treatment only increased the number of deaths which was around 7,000 to 10,000 Cherokees. The Cherokees tribe suffered heavy losses due to the illness and at the end nearly half of the tribe was dead.
Colonist are going to live in a new place that they have never lived before, will they survive? It is the year of 1607, 100 or more passengers were on a ship and they were sailing to Chesapeake Bay.Many colonists are dying and they don’t know the reason why. Many colonists died because of the water, they didn’t have any skills, and because of their relationships. The colonist died because there was not that much water, some water was Brackish water (Brackish water is freshwater that is mixed with salt), there was droughts, and they wanted to dump human waste into the lake. “ Because the adjacent river and creek became brackish as water levels rose, reliable sources of freshwater would have been scarce,” (Doc A).
During the late 1800s Sea Lions were hunted for their skins and meat which led to Sea Lions population to decrease dramatically then a law came out during the early 1900s to limit harvest of these animals so that they don 't become extinct. During the early years of the 1900s Japanese were killing Japanese Sea Lions for their meat to prevent starvation and used their blubber for oil to light their lamps and whiskers used for cleaning material in which their population was already low ranging from 30,000 to 50,000 then in which started leading to their endangerment and ultimately their extinction which came around the early 1950s which they presumed extinct after WWII due to the radiation the bombs gave off when the U.S dropped bombs on Japan. Going back to the sea lions ancestors it goes back to 32 million years ago and shows that Sea Lions were smaller in size like a sea otter and over those millions of years it 's gotten bigger and was close to a Walrus and was similar size but then later shrink down to the normal Sea Lion size we have today over the millions of years. Going through the Sea Lion species the steller Sea Lion during 1977 Steller Sea Lions where announced endangered due to a lot of the population suddenly disappearing to mysterious
In Canada there are many environmental impacts that affect our ecosystems, wildlife, and overall environment. Invasive species are the greatest threat to the biodiversity of Canada’s waters, woodlands, and wetlands. Within Canada’s great lakes there are an outstanding, 185 non-native species entering and altering our ecosytems. One of the most influential invaders is the Zebra mussel. These small, sharp-shelled mussels are believed to have come from ships from Europe in the late 1980s.
