Why Endangered? The Blue Whal

The endangered status of Blue Whales was caused largely by the whaling industry. Whaling. In 1970, the Blue Whale was listed as endangered under the Endangered Species Conservation Act. It is also listed as diminished under the Marine Mammal Protection Act Whaling, which is killing and hunting of whales, is one of the major causes behind blue whales being endangered. People have always tried to hunt whales, but the speed and weight of these mighty mammals made it almost impossible for humans to catch Lesson Summary. The magnificent blue whale is endangered as a result of people's activities in the past and today. Hunting and killing whales is called whaling and has killed hundreds of thousands.. Another reason the Blue Whale is endangered is habitat destruction. This is also caused by humans. This habitat destruction is usually because of oil spills and other human waste. They have to use a loud noise to find these waste areas Whale oil is the major reason of the endangerment of the Blue Whales today Current reasons . The remaining whales are endangered due to reasons such as : • Climate change and how it effects their only food i.e. krill. Whales live on krill and climate change effects the temperature of the ocean which in turn effects krill

But the number of blue whales remains low due to man's deep-sea activities. Heavy sea traffic causes accidents, where blue whales are injured by ships or cargo vessels. Deep-sea fishing involves using large nets and trawling equipment, in which blue whales can get entangled and drown Like other large whales, blue whales are threatened by environmental change including habitat loss and toxics. Blue whales can also be harmed by ship strikes and by becoming entangled in fishing gear The population of blue whales are Endangered meaning they are Increasing. Scientists say the blue whale's ability to communicate with potential mates over large distances have helped stocks recover from a decreasing population due to hunters to an increasing population

Why Are Whales Endangered? | History and the Current Situation Several factors contribute to whales' current endangered status, such as overfishing, pollution, dam/bridge construction, private/commercial boating, and commercial whaling. Still, commercial whaling has had the largest effect on the endangered status of today's whale populations The endangered status of Blue Whales was caused largely by the whaling industry. Since they have been protected, Blue Whales have been able to recover, and there are now 1,500-2,500 Blue Whales left in the wild. In 1966 the Blue Whale was protected from commercial whaling by the International Convention for the Regulation of Whaling These gigantic creatures were almost whaled into extinction until they were declared protected by the International Whaling Commission in 1966. While whaling is no longer considered a major threat for the whale species, they are still threatened by climate change as it affects their main prey, krill. They're also majorly affected by pollution

They are only endangered through man-made causes. Although blue whales are legally protected today, they do continue to face some man-made threats in the form of entanglement, vessel strikes, and other threats. Entanglement. Blue whales can become entangled in fishing gear including traps, pots, or gillnets Blue whales are endangered due to whaling which is the hunting and killing of whales. Whales are extremely fast and extremely heavy. They are the heaviest animal on the planet. Whalers have come up with new ways to catch and kill whales illegally The primary threats blue whales currently face are vessel strikes and entanglements in fishing gear. NOAA Fisheries and its partners are dedicated to conserving and rebuilding blue whale populations worldwide. We use a variety of innovative techniques to study, protect, and rescue these endangered animals

The Scientific Committee, established by the Threatened Species Conservation Act, has made a Final Determination to list the Blue Whale, Balaenoptera musculus (Linnaeus, 1758), as an ENDANGERED SPECIES on Part 1 of Schedule 1 of the Act, and as a consequence, omit reference to the Blue Whale subspecies Balaenoptera musculus musculus as an Endangered Species Why are Blue Whales Endangered?

Blue whales have long, slender mottled grayish-blue bodies. Hunted by commercial whalers until the last century for oil, meat, and baleen, fin whales in the North Atlantic are listed as endangered. Some populations are faring better as a result. Like other large whales, fin whales are threatened by environmental change including habitat loss, toxics and climate change

The blue whale has also been listed as endangered animals. Before the 20th-century blue whales were available in sufficient numbers almost in all the oceans. From the beginning of the 20th-century people started hunting blue whales to get fish oil and very soon it became an endangered species Blue whales reach these mind-boggling dimensions on a diet composed nearly exclusively of tiny shrimplike animals called krill. During certain times of the year, a single adult blue whale consumes. Whales play an important role in stabilizing the aquatic food chain and reproduction of other species. If more whales were to die, it would cause an imbalance in the food web causing the ecology of environment to be destabilized (Blue Whale Facts, 2015).Scientific studies of Cetaceans has given way to countless scientific breakthroughs into echolocation, aquatic environments, and marine. The blue whale is being protected from extinction through several conservation methods, such as being listed and protected under the Species at Risk Act and the Endangered Species Act. These laws protect blue whales under international law and make it illegal to kill them The blue whale (Balaenoptera musculus) is the largest animal known to have ever lived on Earth.It is a difficult whale to study because of its low numbers and its preference for deep, offshore waters. Within Balaenoptera musculus, authorities recognize between three and five subspecies.Blue whales live in oceans throughout the world, including off the Atlantic and Pacific coasts of Canada

Why Endangered The Blue Whal

  1. Climate change may also impact the areas of the oceans in which whales live, including migration patterns. Climate change, depletion in the ozone layer and the related rise in UV radiation may also lead to a fall in the population of krill, a primary food source for many marine species. Together we can make the world's oceans safe for whales.
  2. Sadly, there are only about 10,000 to 25,000 blue whales left in the world today. Though it may sound like a large number, this is incredibly low. The populations of the blue whale have decreased exponentially since about 1911. More precisely, the current size of this animal's population is only about 3 to 11% of its size during the previous.

People in these areas don't depend on whale oil anymore, because petroleum eventually took its place as a fuel mainstay

The blue whales, along with the other great whales, play a key role in maintaining a healthy ocean ecosystem. Through their defecation, whales fertilize the microscopic phytoplankton, upon which all sea life depends. Phytoplankton, in turn, helps mitigate climate change by capturing carbon and also produces more than half the world's oxygen The first washed up blue whale in Africa since the 1986 ban on whaling could be an indication of the population recovery of the endangered animal
