Canadian Seal Hunt The famous Nobel Peace Prize winner, Wangari Maathai once said “Environment and the economy are really both two sides of the same coin. If we cannot sustain our environment, we can not sustain ourselves” This has led me to the belief that the Canadian Seal hunt should not be banned because of the environmental benefits, economical benefits and the health benefits it provides that have been discovered through well developed research. Firstly, the seal hunt is balancing out the ecosystem. Research shows that seals in Newfoundland and Labrador are consuming 250, 000 MT of Turbot, 800, 000 MT of capelin and…
Many American families believe that SeaWorld is the best family vacation spot with its many parks all over the country. A typical visit to SeaWorld includes petting dolphins, visiting the aquarium, and being splashed by a majestic Orca. While SeaWorld may seem family-friendly, it definitely is not animal friendly. The tourist attraction, also known as SeaWorld, tortures its animals by ripping them from their homes and families, placing them in pools that might as well be bathtubs. Although families enjoy taking a trip to SeaWorld, they would feel a lot differently if they knew about the constant pain and torture inflicted on SeaWorld’s animals.…
1) After looking at the graphs in Figures 3 and 4, it is obvious that killer whales are the cause behind the deaths of a large amount of sea otters. Despite the data for Figure 3 showing all sea otter the researchers encountered, while the data for Figure 4 showing sea otters with radio tags, both figures still show a drastic decrease in sea otter population with the only main difference between Kulak Bay and Clam Lagoon being the ease of access that killer whales have to the areas. The researchers looked at 2 different sets of data because they wanted to show the general decline in the population in figure 3 and then show a more specific set of otters to show that the general decline was not because of human error. By having figure 4 focus on…
Seal hunting/slaughter began by the aboriginals over 4,000 years ago. But the Europeans started to hunt seals before everyone else for money problems and started to use nets to catch seals in the early 1660’s. then, in the early 1700’s all the sealers began to use guns and the boats became larger and there was more. In 1723 the seal hunt became an actual annual event for all the sealers. These seals were/are killed for oil which is used for cooking, for soap, lamp oil, some types of lubricants and are used for their popular grey, leather skin.…
No, no way, the Canadian government shouldn't ban the seal hunt due to many reasons. I feel the main reasons are: we would lose resources that we acquire from the seals, due to the increase in population of the seals, fishes that we eat are decreasing in population some are even close to extinct, and that the media is going above and beyond by showing nonsense and causing people to act against the seal hunt which is hurting the economy, specially the fishermans. First of all the seals are killed in a humane manner. The seal fishery is highly regulated and is being closely monitored to assure that the seal hunt is conducted in a proper manner, not torturing the seals. It is no less or more humane than the way other animals that supply us…
Scientific Validity of “Study links altered brain chemistry, behavioral impairments in fish exposed to elevated CO2” Coral reefs are having a problem with pH levels and they are dying some places around the world right now, because of it. This is not only affecting the coral reefs, but the animals that live in them and survive with them. There is a Scientific Study called “Study links altered brain chemistry, behavioral impairments in fish exposed to elevated CO2” which discusses the behavior and neurological impairments of coral reef fish due to more CO2 and acidic levels of pH. More CO2 causes lower levels of pH and makes it more acidic and very dangerous for fish. Overall this is a poor scientific article, because it has only one good source…
According to the article “Search for the Missing Sea Otters: An Ecological Detective Story” by Mary E. Allen and Mark L. Kuhlmann, the sea otter population has been decreasing at a rapid pace since the 1990’s in Aleutian, Alaska. This is demonstrated by article “What Could be the Cause of Decreasing Otter Numbers” which states that in 1997, the decline of the sea otter population had increased to about 90%. They hypothesize that the decrease in the sea otter population has been caused by their predator, the killer whale because the sea otter’s bodies do not come ashore. The evidence suggests that killer whales are eating the sea otters because in the text “What Predator Could be Causing the Large Decrease in Otter Numbers”…

Blackfish is a documentary directed by Gabriela Cowperthwaite, released in 2013. Blackfish is a documentary about a killer whale named Tilikum that has killed several individuals and the issues within keeping killer whales in captivity. The documentary is filled with experiences from former trainers that have worked with the aggressive whales in the past and several experts that have worked with orcas all of their lives. This documentary is showing that the killer whale’s aggression in SeaWorld is provoked from captivity, which goes to show we should not bring wild animals outside of their normal habitat for entertainment.…

Captive research has become less important as the study of orcas in the wild is becoming less difficult. Items such as satellite tagging and biopsy darts have made collecting data much easier. A killer whale feces has even given scientists large amounts of information about orcas without having to disturb them (Raja). Another argument that is made constantly is that SeaWorld extends the lifespans of its animals. Multiple SeaWorld employees claim that because they have the correct veterinary tools, orcas will live longer (Cowperthwaite).…
The power of emotion: compassion In Marina Keegan’s essay, Why We Care About Whales, Marina claims on how humans value the life of humans and the life of non-human animals. The essay starts with a social occurrence of emerging beached whales. A natural force that is created by the movement of both the moon and the Earth push whales to the beach. While giving a detailed, vivid explanation of how beached whales die, Marina maximizes the sadness and lamentation of whales’ deaths. Furthermore, she describes her anecdote, which was happened at the beach in front of her house.…
Killer Whales are a very large and strong breed of marine mammals that belong to the dolphin family that can grow up to ten meters long and can weigh up to six tons. Theses whales are a highly social species that are very intelligent with an excellent sense of hearing and have developed highly complex communication systems. Killer whales are immediately recognizable by their distinctive black-and-white coloring, when you see these magnificent creatures many people immediately get the idea of Shamu from SeaWorld and the tricks they preform, most people don’t remember that that captivity is limiting the whale’s freedom and life. Captivity is not only taking away and damaging these animals mental and physical health, it is also playing a role in taking the lives of the trainers that risk their lives swimming with killer whales just to make a profit for SeaWorld.…
