It is required to conserve a certain population-level of every specie in order to prevent biodiversity loss and for ecosystems to continue operating. Whales are starting to extinct and whaling is one of the important causes of this problem. The blue whale is the largest animal and a lot of them are found in the Antarctic. The specie reduced abundantly because of hunting in the 20th century. The Antarctic blue whale is classified as Critically Endangered on the International Union for Conservation of Nature (IUCN) Red List of Threatened Species. The whales are now protected from commercial and scientific whaling. Climate changes are also having and impact on the whale population in feeding grounds, as well as tourism, krill fishery and research

The information and details given were sometimes too methodical and meticulous for my essay, but were trustworthy. The main subject of the article was the population-level conservation of the specie, but the author reached his subject with an approach and examples allowing me to learn more about the basic whaling, climate and consequences on the whales in a more “student adapted” language. The vocabulary used was occasionally mathematical and formal because of the use of methods and formulas to explain the genetic clusters and population structure of the mammal necessary for the research. I found this article interesting and complex. The theories were well explained and kept a neutral point of view, which was pleasant. I have learned more about endangered whales by reading this article and it permitted me to dig deeper in the subject than other more basic …show more content…
The anthropogenic noises from cargo ships, sonar, seismic testing, drilling, pile drivers, recreational holiday ships, and etc. can cause auditory masking leading to cochlear damage, change in behavior, altered metabolisms and malfunctioning health and ecosystems. This noise pollution can increase the stress of animals and interfere with the sound-based orientation. Biotic and abiotic sounds are the two components of underwater environment produced by fish and mammals in order to communicate and orient. Acoustic masking is one of the main effects of noise pollutions on marine animals. The noise from boating and shipping has an effect on fish and hearing abilities and physiological damage on their hearing systems. The sound of the boats also avoids responses in the herring. Some noises made species more vulnerable to predation because of a slower behavior after detection of a simulated. The noise pollution also leads to physiological stress responses in marine organisms, such as stimulating nervous activity, increasing metabolism, and reducing immunity. Noise exposure has also led some whales to
