London SW2 Hayes Middlesex UB4 OQA 26.02.2010 Dear Sir or Madam, I am writing to draw your attention to problems concerning threats that are connected with fishing. A study shoes that, rather than pollution, fishing appears to be the biggest threat to porpoises. Each year more than 10000 porpoises are killed in the seas around Britain. Fishingboats are using a technique witch consists in leaving the nets on the sea bed for several hours. When porpoises come to feed on the sea bed, they get caught in the nets and drown. There is a need for a research to make nets safer for porpoises. For example, one possibility would be to restrict the length of nets. This should be a duty of marine mammal organisations. Also should be limited the allowed amount of fish to be caught
known at the time. The classification is thus heavily weighted toward whales hunted for oil and other uses, and presents a picture of the common knowledge of whales at the time of the novel. Since Melville presents the study within a fictional context, voiced by a fictional character in the narrative, it is arguable whether or not Melville intended the classification as a serious scientific contribution. Moreover, Melville includes the larger members of the Cetaceans, as well as the porpoises (dolphins). It is quite possible that in the case of the Duodecimo whales (porpoises), Melville has unknowingly combined many disparate species into a single "chapter". Transcendentalism and its importance for the development of the Americans' outlook. Ralph Waldo Emerson. Henry David Thoreau. Literature of Abolitionism. Harriet Beecher Stowe's Uncle Tom's Cabin as a powerful exposure of slavery.
