Impacts Of Blue Whales

However it is critical to understand that when they are conserved in captivity, we prevent them from getting their main biological needs from the ocean as a natural habitat. With their wide food spectrums, orcas hunt for turtles, sea lions, crabs, seals and many other food varieties depending on their ecotypes. This makes them travel over large regions in the ocean in search of the same. Just as human beings are top of the food chain with regards terrestrial animals, so are orcas in the oceans. It is therefore important to raise our voices against this practice to avoid the risk of classifying them as endangered species. Even though the whales “gave me so much in my life and my career” (BioExpedition 1), he grew to believe that the whales’ physical and emotional well-being was incompatible with captivity. Confined to unnatural social groups for the convenience of their owners, bored and restless, forced to perform tricks for food that trainers withheld as punishment, they occasionally slipped, he writes, “into the dark side” (Adler 2).

There is no doubt that humans have always been intrigued with the majestic beauty of the large giants found in all of the world’s oceans. Whales and people have had a long history together, marked by many turns of events.

Humans fish to survive and in doing so they will target specific species leading to overfishing. Sound pollution is causing issues with the wildlife of the ocean in how they communicate and move around. With human interaction comes trash which gets left in the ocean and affects many different species.

The panda of the sea is in danger. The local Southern Resident Killer Whale J,K, and L pods population is disintegrating quickly. This is due to habitat destruction, reproductive issues, and a limited food supply. All of these factors are causing the Southern Resident Killer Whale population in the Pacific Northwest to decrease drastically and now they are a species that is listed under the Endangered Species Act. According to whale researcher Ken Balcomb, “The SRKW population was declared Endangered under the US Endangered Species Act in 2005, and earlier this year it was listed as a “species in the spotlight” by NOAA for its lack of recovery since then”(Balcomb). With recent deaths of J28 and her calf J54, many whale activist have been pushing

and they are dangerous in captivity. It is clear that whales should not be held in captivity. Whales

Orcas are complex social creatures deserving freedom and respect, not captivity in theme parks under the guise of public education and entertainment. Aquarium staffs say captive whales are priceless educational tools. However, people can educate their children by bringing them to the wild instead of bringing the wild to them at the expense of the Orcas health and well-being. "The price of a family admission ticket is what continues to drive this cruel spectacle," according to Michael O' Sullivan, the Executive Director of The Humane Society of Canada (Whales in Captivity, 2010, Para. 3). Orcas suffer in many ways in

For years the killer whale, also known as Orcinus orca, has been drawing the attention of the public through the entertainment industry. These marine mammals have been bringing in billions of dollars to amusement parks such as Sea World, but at what cost? An idea that these killer whales can live happily and content while in captivity may be going through the minds of the public, but this cannot be further away from the truth. To have such complex creatures in captivity is not morally correct and there are many points against it, such as their level of emotional competence, violence between the killer whales, violence of killer of whales towards trainers, shorter lifespans, physical harm, and their level of intelligence. After taking a look at how these creatures function and the conditions they are put in while in captivity, there is no question about whether or not these mammals should be kept in captivity; an experience such as this affects these marine mammals just about the same as it would affect a human because of their high highly developed emotions and complexity. Since these industries do not have a natural authority over these creatures no matter the cause, the best thing they could do for these killer whales is to stop capturing them and return those who are capable back to the wild.

The research shows that killer whales are not healthy in captivity. But we can stop this and seaworld has taken some steps to help solve the problem that orcas aren’t healthy in captivity. This problem affects the orcas big time, and the trainers that take care of them. Killer whales in the wild are having a great time, but remember in some countries there are no laws stopping them from catching or killing orcas. Maybe we should call them killer humans, instead of calling orcas killer whales because they’re really the problem. Research highly suggest that they expand their tanks or just plain out stop pulling killer whales out of the ocean. Some laws have been passed in the US to stop people from killing orcas or pulling them out of the ocean.

Although there are many problems, there are also many solutions to save the killer whales that

The ocean is a vast biome that is constantly changing. There is much to learn about the life within, the article “Omura's whales (Balaenoptera omurai) off northwest Madagascar: ecology, Behavior and conservation needs” showed how our knowledge of the ocean and the life within continues to grow. Balaenoptera omurai, or Omura's whale was only found as a new species in the year 2003. Their are no dependable population size estimates or evaluation of conservation facts because there is not enough data collected on these cetaceans. Scientists are able apply what they learn from some of these organism to humans. In the article “Reproductive Conflict and the Evolution of Menopause in Killer Whales” scientists were able to draw comparisons between Humans and other species.

Holding killer whales in captivity is a harmful problem to the mammal that requires action from both the government and the public.

Whales have a distressing increase in assimilating cancer, along with getting other illnesses like nervous and digestive system problems, liver disease, contaminant-induced immunosuppression, endocrine system damage, reproductive malformations, and growth and development issues, all because of ocean pollution (Bluevoice.org). According to “The Effects of Ocean Pollution on Marine Mammals”, by Bob Bohle, it states, “...from overfishing to greenhouse gases and global warming to the introduction of toxins into the environment – has affected every square mile of ocean on the planet and strongly impacted roughly 40 percent of marine ecosystems.” This shows far ocean pollution has come. As stated before, humans are now catching the effects of ocean pollution. Toxins from plastic and mercury that end up in fish, are entering the human food chain, which are now being linked to cancers, birth defects, immune system problems, and childhood development issues (Gianna Andrews,

Today, killer whales are in danger of becoming extinct due to pollution of substances like PCBs. Due to biomagnification, chemicals like those mentioned only magnify in populations higher on the food chain. How does this effect the orca population? Pollution at these levels are creating various health issues in the large mammals and decreasing their numbers rapidly. Equally worrisome is the fact that humans consume the same contaminated food as orcas (e.g., salmon).

Commercial whaling is a serious world issue that has always been difficult for those who are in support and those who are against it. Each group defends their side with convincing arguments. Morally, whaling is wrong, but do the reasons for whaling outweigh the reasons to cease the primitive hunts? By studying the effects of whaling,realizing how culture has changed over time, and taking note of the money that would be saved, it can clearly be seen that there is no longer a current need for whaling to continue. Efforts have been made to try to stop whaling, but with no help from any authoritative figure,nothing has been done to regulate the whaling. The famous sea shepherd, known for its strikes against whaling, can even be seen on

Whaling has become a global environmental issue as vast numbers of whales are killed commercially and scientifically every year. Intense debate on the necessity of whaling has been stirred but failed to be resolved due to the lacking of pragmatic measures employed by the responsible parties. Whaling nations continue to defend their whaling right for cultural and research purposes. Yet, ethical and humanity issues are among the controversial disputes raised by concerned public. In February 2010, International Whaling Commission (IWC) proposed a plan of lifting whaling ban by limiting scientific whaling activities with the intention of reducing overall number of whales killed besides solving the current impasse between pro
