The Effects Of Pollution On Killer Whale Populations

The effect on orca whales being held in captivity is not the greatest, and the history between humans and the whales that are held in captivity is also not very good. It is a subject that many scientists are working together to learn about. Even though the orcas help to educate kids by doing live shows and by helping the kids understand that they need to save the orca whales that are endangered, orcas should not be held in captivity because many accidents have happened between humans and the captive orcas and it is not good for their health. Another name for the orca whales is the scientific name, “orcinus orca”, or the name that you probably hear most often which is “killer whale”. These killer whales have been known for attacking humans,

“Around 195 Orcas have died in captivity, in addition to 30 miscarried or still-born whale calves. SeaWorld is a major role in Orca endangerment, holding 23 Orcas across their five parks in the United States: Florida, California, Texas, Virginia, and Pennsylvania”(“The Fate of Captive Orcas.” WDC). SeaWorld’s distinctive entertainment is detrimental to the health of Orcas; bringing stress, frustration, and aggression. Most guests of SeaWorld do not realize the animal abuse that exists in this chain of “marine mammal parks, oceanariums, animal theme parks, and rehabilitation centers owned by SeaWorld Entertainment”

Oceans cover approximately 75% of Earth 's surface and are vital to this planet and the people who inhabit it. Oceans provide food, natural resources, and recreation for nearly everyone in this world. Unfortunately Oceans have been receiving mass amount of pollutants including oil spills, toxic waste dumping, and industrial dumping. These pollutants will have negative impacts on the wildlife in the ocean, as we are seeing already with the Coral Reefs, and soon enough it will begin to affect our lives as well.

the whales is also bad. When they take the Whales from the ocean, many whales die in the

There are numerous harmful effects of keeping whales in captivity. For instance, there is often a decrease in survival rates, the orcas begin to convey rough behavior, and there have been an increasing amount of human injuries and deaths within the past few years. However, some individuals believe that companies such as SeaWorld are doing the public a favor by educating families about wild whales. Also, some believe that the quality of life is better in captivity than in the ocean. However, while keeping killer whales in captivity might appear as a harmless entertainment act to the public, there are numerous cases of evidence that further support

Cetaceans use sound extensively in both communication, hunting, and navigation. However as humanity continues to make use of the ocean we are constantly filling it with equipment that produces high amounts of sound. These devices are starting to have an impact on cetaceans worldwide, from mass strandings often linked to military exercises to area denials caused by busy commercial shipping lanes and seismic surveys. If consideration is not taken towards this problem now it could develop into something that could have degrading effects on cetacean populations in the future.

At least 164 Orcas, Killer whales, have died in captivity all of them being premature deaths. Orcas should not have to suffer in captivity and should be left alone and stay in the wild. All Orcas in captivity will die at half there age. They must live in tiny tanks equaling to us living in a bathtub. They are captured from the wild when they are young and are taken from their family and then forced to interact with other whales from different whale pods which also speak a different language then them.

Killer whales were not considered a threat to humans until one day in February 1991. Keltie Byrne, a marine biology and former killer whale trainer was killed by Tilikum. According to the reports, she slipped from the tank, where Tilikum was located, prevented her from surfacing and killed her. Sadly, another tragedy of a trainer who was killed by someone she knows

Today, the global theme park has 41 killer whales live, in which 26 marine parks in Orlando. Over the years, more than 130 killer whales were captured after the death. Until the 1960s, it has never been thought about the killer whale into the aquarium, not to mention, and who perform together. The public know very little about this animal, in addition to their name sounds very dangerous. Killer whales, also known as orcas, or killer whale, is the largest member of the dolphin family size. The fishermen used a rifle to shoot killer whales near the fish.

Killer whale is known as the Orca or their scientific name, Orcunus Orca. Killer whale is the largest of the dolphin family and also the strongest and powerful predators. The Orca has the name killer whale because they can take down any large creature such as seals, sea lion or even white shark. The killer whale’s current population range is about 50,000 and they are the most distributed marine mammals. Their territory extends from the Artic to the Antarctic but they mostly can be found in the cold-water upwelling areas such as the Pacific Northwest, the Southern Ocean that has high latitude. Not only they can be found in the cold ocean, many data has also shown that they have been seen in the warmer area such as Florida or Hawaii. They are predators, so they eat marine animals such as seals, sea lions, fish, sea turtles, birds or even the great white shark. The difference between the female and the male killer whale is the male Orca is 32 feet long; weight 22,000 pounds with 6 feet tall dorsal fin while the female Orca is 28 feet long; weight 16,500 pounds with a little curve dorsal fin on the back. Their color is black on the upper body and white color on the lower body with gray saddle on their back or behind their dorsal fin. They have two white spot on the side of their face called eyespot. Even though the eyespots look like the eyes, the Orca’s eyes and ears are actually located below the eyespots. They depend on their sound and vocal to communicating, navigating,

Keeping whales in captivity is so cruel that the whales became erratic and could kill people. Ms Brancheau's death demostrates that close contact with killer whales is a hazard likely to cause death or serious injury additionally osha found that Seaworld had violated the general duty of clause of occupational safety and healthy exposing trainers to recognized hazards when they are working in close contact with killer whales.

It’s also highly morally and ethically wrong to keep killer whales in captivity because of their intelligence. Killer whales “have the second-largest brains of all ocean mammals, and are believed to be one of the smartest animals on the planet.” (Independent) They are not able to use their intelligence their natural way in captivity. Whales in the wild “build complex family lives as well as sophisticated hunting techniques” (Independent) but captive whales are suppressed

After arriving at the aquarium, the whales are put into tanks that are a maximum of 40 feet deep and 80 feet wide, much smaller than the 100 mile area an Orca would swim daily in the wild. To put things into perspective, the human equivalent to these tanks would be about; 10 meters long, 6 meters wide, and 2 meters deep (WDC), which is about the size of 2 school buses parked side by side. Among other things, the tanks are harmful to the whales for three main reasons. The first reason is the tanks are much too shallow for the whales to dive down into the shade of the ocean to escape the suns hot rays. This being said, the whales are forced to stay on the surface much more than they would in the wild, resulting in extreme sun burn.

By calculating the amount of food lost because of dropping sea levels, and combing this with estimates of the food needed to keep a whale alive, Lindberg and Pysenson calculated the impact of global cooling on gray whale populations and the populations that would have had to exist in order for the whales to survive. They then concluded that populations would have had to have alternative feeding modes sufficient to support a population of around 70,000 during warm periods so that population drops during glacial periods wouldn't be below 5,000 to 10,000 whales. Much lower numbers would have produced a genetic bottleneck obvious in the DNA of the whales and Lindberg stated "such a signature has not been
