To control the overfishing and growing industrial fishing market, in 1977 the Canadian Government introduced a 200 mile management zone but by that time most of the ecological damage had started. However, during this time other industries like resource-extraction failed, which put pressure on the fishing industry and even the government had to encourage more catching of fish for exports. However, as stocks of cod fish continued to drastically decline the government finally decided to ban cod fishing in 1992. Though the cod fishing industry boosted the Canadian economy and provided employment for local
El Niño’s have been occurring for about 10,000 years since the last Ice Age. When an El Niño occurs it decreases the rise of cold water off the coast of the Americas. “When this happens the fish either die or migrate into areas that they will find more to eat” (wildlife.ca.gov). When this happens in the in the Pacific close to the Ecuador the Galapagos fur seals struggle to find food. When the fish are gone the wildlife that depend on them for food will die also.
He compares the mass extinction of various animals 65 million years ago (Glavin, 2013, p. 167) to the depletion of big fish in the sea. This presents a false analogy fallacy (Henderson, 2013, p. 52), as the extinction of dinosaurs and near disappearance of cod have very little in common, and appears to exaggerate the situation regarding the exhausting populations of fish. Furthermore, the article later goes on to discuss sustainability in fisheries (Glavin, 2013, p. 168-169), veering off the topic of defending seal hunting. The author makes references to how the Marine Stewardship Council and their "eco-label" are forcing fisheries to take up more sustainable practices (Glavin, 2013, p. 168-169). This information appears to be encouraging the reader not to boycott seafood because the seafood is becoming more and more sustainable.
Newfoundland was known for its Cod fish industry and the prohibition that followed since the early 90s. The dropping numbers of the Cod fish was escalating and it took a governmental standard ban to stop the excessive fishing, even though it was disastrous to the economy. The restriction on Cod fishing was considered a wise thing to do. With or without the ban on Cod fishing, there would’ve been a stop to the overfishing. Whether if it was by legislative power or just dead near extinction of Cod in North Atlantic.
Japan’s Ministry of the Environment officially declared Lutra Lutra Whiteleyi or better known as the ‘Japanese River Otter’ extinct in the wild. Many searches have been conducted over the past years but the last sighting was still in 1979. The Japanese River Otter was a subspecies of the European Otter. It mostly ate shrimp and fish and could grow to be 1 meter long. It is thought the main reason for it’s extinction is due to overhunting, because it’s fur was considered very
Zebra mussels are a big problem because they cost the economy lots of money, eat up almost all of the plankton, and they hurt aquatic life. My first reason we should rid of the zebra mussel is because they cost the economy lots of money. According to the article Zebra Mussels by MNDNR, “Zebra mussels can be a costly problem for cities and power plants when they clog water intakes.” They cost America 5 billion dollars a year just to replace things this small mussel has ruined. My second reason that we need to remove the zebra mussels
Zebra Mussels are invasive species who came to canada accidentally by ballast water ship.This invasive species arrived to canada at late 1980’s came to Ontario and Quebec and it first came to lake St.Clair and get speared to south to Gulf of Mexico and further speared to southern Canada.This invasive species Zebra Mussels is native Caspian region. Zebra mussels lay 1,000,000eggs per years. Zebra mussels are bad for Canadian environment because it eat all the food for fishes and then their will be no food for fishes to eat and then fishes will get extinct that’s cause fishes to extinct.It was first described in 1769 by a german zoologist name Peter simon
The number of animals is from 2 – 50 million. Yes, there’s less animals than there are of humans, but what if both animals and humans were to decrease, you may ask? Well, the Circle of Life is one thing, but to have both animals and humans die at the exact time is dangerously crucial. It’s dangerously crucial because there are 16,306 endangered species threatened with extinction, according to www.endangeredearth.com. If those endangered species die out, in addition to our everyday North American Species of birds and mammals, then we have no chance of survival due to BPA still existing.
Invasive species are said to be one of the most expensive problems being faced by the government. This is why people want the government to stop spending billions of dollars on this management, when it could go towards making more jobs for citizens. Monica Dawson, author of Pythons: 8 Facts about the Exotic Pet That 's Ruining the Florida Everglades, wrote, “What most people do not know is that these Burmese pythons can still cost the government money even when they are not removed by employees of the invasive species management program.” Faine Greenwood, The Global Post noted, “ that it costs over $93,992 every year for the feeding for one Burmese python and continued efforts to decrease the overpopulation of the species would greatly lower the
The lecturer and the reading passage offer two theories to explain why the sea otter population is in rapid decline. The two theories are predation theory and pollution theory. The professor argues predation is the more likely cause than pollution because of the absence of dead sea otters washing up on shores. However, the reading passage attributes the decline of the sea otters population based on evidence of increased ocean contaminates leading to greater vulnerability to infections. Also, the lecturer argues that orcas are likely factors in the population decline of the sea otters because of the scarcity of their usual prepay.
The rivers and streams of the Kenai River inhabit all five species of salmon found in Alaska, contains millions of fish and spawns the largest amount of Chinook salmon worldwide. The southeast border has thousands of short, productive coastal rivers. Bristol Bay, a land of lakes and coastal rivers, support the majority of Alaska’s sockeye population. The Alsek, Taku and Stinkine Rivers are the three great salmon producing rivers of the southeast; these rivers, along with the Yukon, are transboundary rivers for the salmon ahrvest of Canada and Alaska. The Susitna River watershed drainage is home to many important salmon populations.
Firstly, they would drink 2.6 gallons every 5 days for 240 days. Secondly, 240 days overall divided by every 5 days would be 48 days of distributing drinking water (240/5=48). Thirdly, you would have 48 distributing days multiplied by 2.6 which is the amount of water distributed this would give them 124.8 gallons distributed in the 240 days to a single person (48 x 2.6= 124.8). In the final analysis, they have multiplied 124.8 by 4 since that is how many people are in their group which gave them 499.2 gallons of water used (124.8 x 4= 499.2). Since only 41% of the cow and bull’s weight are consumable the group has a total of 409147.2 grams, or 902 servings, of consumable meat divided by four (902/4=225.5) then into 1.5 servings, or 680.4 grams, per 2 days and 3 bushels of wheat that is plenty for the first 120 days.
