2016). Overall, in the past 75 years the global whale shark’s population has declined by 50% (Pierce, S.J. & Norman B. 2016). Whale sharks are protected species in 13 of 100 countries that they visit every year and is classified as a vulnerable species (Rogers M.
It’s perceptible that the ocean’s economy is really important, however but due to overfishing, it is costing many people their jobs. An example of this is, in 1992 when the cod stocks in Newfoundland have depleted to the point where the fisheries had to close down. 40,000 people were put out of work due to the low stocks. At first, it was supposed to be a two- year closure to let the cod replenish. After those two years, there wasere even less cod.
As a result, the hungry Iñupiaq people in Barrow decided to pay no mind to the law and protested. This tragic event proves that the law cannot jeopardize the Iñupiaq people’s way of living. This event showed leadership by taking pride in the culture, working together, and by making the citizens of Barrow voices heard. The warden first arrested John Nusunginya for hunting ducks off- season and shortly after Tommy Pikok Sr. Pikok was outraged due to the fact that he could not provide food for his family and therefore, he kept rebelling. He exclaimed to the warden that they should go ahead and arrest him, however, if he comes back from jail and his children and wife are skinny, he will hunt the warden down and feed him to Tommy’s dogs.
In Mcewen’s article river restoration project offers a sprinkling of hope” he states that “san joaquin... has temperatures more suited for bass and bluegill. So thanks to the choice of fish, the project will result in failure thanks to the salmon when it could have succeeded with bass or bluegill. Due to the poor thought on the matter the government
In the other hand, the speaker contends this by explaining that whales were declined because of the human hunting , orcas changed their diet to survive and because just of the sea mammals were available, human started to hunt sea mammals and cause the decline. Third, the author asserts that scientist believed that the pollution hypothesis could also the uneven pattern of otters decline. However, the professor opposes this pint by explaining that the uneven pattern is better explained by orcas predation theory. she added that it depends on whether the location is accessible by orcas or not, so because orcas are large, they can 't access the shallow region where sea otters have not
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
Since late 2004, Harpseals.org has been promoting the boycott of Canadian seafood in order to pressure the Canadian fishing industry to stop supporting the massacre of seals. In 2013, Harpseals.org added a boycott of Namibian seafood to end the Cape fur seal slaughter. So the reason that they are Boycotting Canadian Seafood is because most of the Canadian sealers are fishermen. Sealing is an off-season activity for them, just a way to earn a few dollars before the start of the fishing season. Their income from selling pelts is only about 5% of their income.
The government wanted clean teeth, but instead got disease and death. The government wanted us to remain healthy and have fresh teeth with every drink of water, but we got sick and most had died yet they still continued with the fluoride. The people of America are sometimes too naïve to figure out what the government does to us, and some are actually smart enough to stand up to them and call them out on their mistakes. The main cause of death in America, when it comes to disease, is cancer. It ravages the American landscape and takes thousands of lives a year.
(show size comparison of human to blue whale) That’s the relative size. We’re producing waste equivalent to the mass of 4357 blue whales. It’s phenomenal. As of June last year, our population stands at about 5.47 million (Monthly Digest of Statistics Singapore, February 2015, 2015). That’s about 144kg per person per year c. Out of all that food we wasted, only 13% is recycled into compost and others (Nea.gov.sg, 2015).
Overfishing is serious problem in the world today, more than half of the world’s population depends on the oceans for their primary source of food. Harmful fishing methods are unnecessarily killing turtles, dolphins, and destroying critical habitats. Global warming is increasing the temperature of the ocean water, reducing the generation of the base of the food web, plankton. The reducing of the plankton generation is causing major marine ecosystem change. Pollution is also a significant environmental issue HAL is facing.
The reading states that the pollution hypothesis seemed the more likely to cause the decline in the sea otter populations and provides three reasons of support. However, the professor states that the predation hypothesis is the most likely the cause of the sea otter decline in populations and refutes each of the others reasons. First, the reading states that the oil ridgs and other sources of industrial chemical pollution caused the death to the sea otters. The professor opposes this point by saying that the pollution theroy is weakened because people did not find dead sea otter on the beaches of the sea, and that supports the predation theory because if the sea otters were killed because of the pollution, they should wash up to the shores, and that did not happen.
Imagine a world without any fish in our ocean, nothing for the next generation no ahis mahi mahis ,marlins and many more fish we won’t have if over fish our oceans. I feel that overfishing in Hawaii is a major problem for 3 reasons such as people are taking fish that are under the size limit on the fish, another example is people are taking the fish that are the big breeders and they don’t give them a chance to repopulate and for the last example is people are taking more than they need and it could be a waste because it just sits in the freezer. The first reason I think overfishing is a major problem in Hawaii is because people are taking fish that are small and under the size limit that they should be taking. This is a problem because they are not giving the fish enough time to reproduce also that when the take the small fish is a problem because, there is not enough meat on that fish anyways so they pretty much just took that fish and wasted it because it to small. They should of have let it go to grow as they say in the island “let um go let um grow” many people
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 increasing temperature in the Columbia and Snake River Basin will provide less of a habitat range for the cold water species, sockeye salmon. The reason being that if the salmon were to attempt to inhabit these warmer waters the individuals that are unable to physiologically acclimate to these new temperature conditions will die; thus decreasing the relative abundance of the sockeye salmon’s population in these areas. The decrease in the amount of sockeye salmon will in-turn affect the communities and interactions of organisms living in the Columbia and Snake River Basin. b. With an initial population of 500,000 sockeye salmon and only 272,000 making it to the spawning grounds.
