Jimmy Carter wrote this essay to persuade his audience that industry should not develop Arctic National Wildlife Refuge for its resources . Carter used evidence, such as facts and examples to support his claim. In Carter’s writing, he clearly shows the reader how the Arctic National Wildlife Refuge remains America’s last truly great wilderness. Many animals live there, for example, the polar bears, caribou, Dall sheep, and wolves.
The bald eagle is the national symbol of the United States and was on the endangered list due to eggshell thinning which was caused by DDT. “DDE and its parent pesticide DDT were used to control mosquitoes and other insects. The chemical was linked to egg shell thinning in bald eagles. It was banned in 1972” (Murray). In 1995 the bald eagle was moved to the threatened species list and was removed from the list in 2007.
Prompt 2 I believe that Sharon Levy presents her text about protection of wolf populations better than Ed Yong’s text. She displays more statistical facts about how wolves are being hunted and trapped on a regular basis. For example, she says in line 15, “ In Alaska, up to 50 percent of wolves are shot or trapped every year, with little effect on their numbers.”
The owl and its habitat are of immense scientific value, providing opportunities for inquiry and for increasing our understanding of this unique ecosystem and its role in our lives and in those of future generations. To date, little research has been done on these forests in the Pacific Northwest. To allow their extinction is to permanently destroy the possibility of exploration and the benefits generated by new
In the 1900s the Environmental Protection Agency listed the bald eagle as an endangered species. During those years, DDT usage was widespread, and it is believed that its use was responsible for the decline in the number of eagles. DDT is a chemical that was used to control mosquitoes, and it caused a thinning of the eagle egg shells. The population of breeding pairs of bald eagles has changed in several states over a 12-year period as is shown in the table below. Population of Breeding Pairs of Bald Eagles State Year 1 Year 3 Year 6 Year 9 Year 12 Maryland
Aside from the otters, dolphins, and seals there are Shamus that are being taken out of their natural habitats. When this happens it causes unnecessary mental stress which can cause deaths of Shamus or trainers. For example, a notorious Shamu named Tilikum just recently died in captivity January 6, 2017. Tilikum was involved in the death of three people: a trainer at the now-defunct Sealand of the Pacific, a man trespassing in SeaWorld Orlando, and a Seaworld Orlando trainer. This is what happens when animals are held in a small confined area.
Although it is nearly impossible to get an entirely accurate count, there exist at least 6,500 languages. Something tells me that if language were about something as simple as communication, that number would be smaller. In all actuality, people feel deeply connected to their native languages for another reason. Language and culture are one and the same, and Gloria Anzaldua illustrates this in her piece “How to Tame a Wild Tongue” using examples of changes and suppressions of her language, to represent changes and suppressions of her culture as a whole. This evident not only in the piece itself, but through much of linguistic discourse as well.
The number one priority should be to increase the survival rates of the female juvenile monk seals; doing so will ultimately increase the population size. With the programs such as Head Start and the translocation program at French Frigate Shoals, there was evidence of improvement in the monk seal population, but as always there was a decline that followed. The current Recovery Plan for the Hawaiian Monk Seal states that for the monk seal to be downlisted from endangered to threatened, the population needs to be more than 2,900 individuals in the Northwestern Hawaiian Islands and that at least 5 of the 6 main sub-populations need to have more than 100 individuals (National Marine Fisheries Service, 2007). For this to occur, the main criteria that needs to be addressed is the pup and juvenile survival rates. The Hawaiian monk seal population cannot continue to survive and grow if less juvenile female pups are reaching reproductive age and not surviving, this has caused the current decrease in Hawaiian monk seal populations to continue to decrease and to decrease more rapidly (Norris et al, 2011).
Four million birds are estimated to use the Sea each day in the winter, more than any other resource in the nation” (DesertUSA, The Salton Sea, CA). Some rare birds that can be seen on special occasion are Bald Eagles, White Ibises, Pine Warblers, Red Crossbills, and over fifty other rarities. Some common birds are: killdeer, Caspian terns, American Avocets, Great Egrets, burrowing owls, Black-necked stilts, and Black skimmers (5). One species, the Yuma Clapper rail, relies heavily on the survival of the Salton Sea because around 40% of all Yuma Clapper rails in the United States live in the basin. These birds were listed as endangered on March 11, 1967 and also rely on the basin for crayfish to eat.
The successful return of sea otters on North America’s west coast Though the Gold Rush of 1849 is considered one of California’s significant historical events, the Californian Fur Rush is much overlooked in Pacific America’s history. Dating as far back as 1741, the Californian and Alaskan coasts were targeted by American, English, Spanish, French and Russian fur traders harvesting the warm pelts of the sea otter, fur seal, beaver, river otter, marten, fisher, mink, fox, weasel, and harbor seal. Sea otters (Enhydra lutris) were particularly overhunted and their populations suffered serious fragmentation up the west coast, coming dangerously close to eradication in this area (Estes, 1990). This essay will discuss the history of their decline
In today 's modern world as we expand, we are taking away habitats from animals and other diverse ecosystems. By doing this we are causes animals to become endangered and extinct. One animal that is harmed by the expansion of humans is the manatee. The manatee lives in warm shallow water next the the shore because that is where the animals have access to food and other resources.
Due to the fact that only Native Americans were in the Oregon Territory, and they used animal products efficiently and did not hunt unless it was necessary, the animal population was very high. The main animal hunted by trappers were beavers. Their fur had become a commodity due to the near extinction of the creature from over hunting. “The possibility of profiting from the western beaver trade had led,”(McNeese OL) many to the territory in search of wealth and fame.
Last Thursday, I took the metro to Peel and then walked north up Peel to the mountain’s edge. The mountain was rather busy given that it was a week day. It’s really an easy trek once you’re downtown, all you have to do is find the mountain, and begin walking up towards the base. The air was particularly crisp on this chilly October morning which blended well with vibrant coloring of the trees. When I reached the outskirts of the mountain at Peel and av.
Sixty years after the extirpation of wolves in the Northern Rockies and Great Plains of America, biologist and ecologist in Yellowstone National Park reintroduced wolves into a declining ecosystem that once thrived during their presence. The reintroduction brought immense controversy into the West and continues to stir outrage among anti-wolf groups. These anti-wolf supporters argue wolves are ruthless predators that cause destruction to natural environments and livestock. Conversely wolf advocates and scientists suggest that wolves are a keystone species that are essential to the natural regulation of our Western ecosystems. Although pro and anti-wolf advocates can agree that wolves have an effect on livestock, ungulate populations and ecosystems,
Native Americans were seen as a small price compared to the industrialization of loggers, miners, and white homesteaders. With the depletion of wildlife, the United States began to recognized the importance of wildlife on the culture, economy, and religion of Native American tribes. State agencies now preside over fish and game to closely control the hunting of wildlife by setting limits on methods, seasonal harvest, and size of animals to ensure a healthy population. The Marine Mammal protection act of 1972 states “recent legislation generally forbids the taking, possession, or sale of designated species by any person subject to federal jurisdiction acting without federal permission” (U.S.C. 1372
