A moratorium on commercial hunting of whales was finally put in place by the International Whaling Commission IWC in late But some countries continue to hunt whales for profit, notably Iceland, Japan, and Norway. Even though actions are being taken and bans are being placed, the number of whales in the wild has reached a critically low number due to over-whaling, and at least seven of the 13 large whale species are either endangered or vulnerable even after many years of protection.
Some cultures also used the meat, although most did not. Whale oil obtained from sperm whales, right whales, and bowhead whales was especially in high demand. A single large sperm whale could yield as much as three tons of sperm oil.
However, the use of whale oil declined in the mid's as kerosene and other petroleum products started replacing its use. Indigenous people also hunted whales because of their meet to fulfil their basic survival needs. For thousands of years, the climate in Greenland was too cold for many people, including the Eskimos and the indigenous people to grow their own vegetables.
Whale meat, other marine mammals, and fish became the main source of food for them, being rich in niacin, iron, and protein. Today, modern whaling is conducted primarily for meat in commercial whaling.
Whales are also being killed in a misguided effort to reduce competition for fish, and several small cetaceans like smaller whales, dolphins, and porpoise species are hunted for the use as a bait to catch fish, especially sharks. It appears that not much has changed. In places like Norway, Iceland and Alaska, you'll find whale served with minimal seasoning, if any [source: Palmer ].

In death they provide life for hundreds of marine animals for up to 50 years, further proof of the vital role they play in the life cycle within Earth's oceans. Every year, more people are reading our articles to learn about the challenges facing the natural world.
Our future depends on nature, but we are not doing enough to protect our life support system. Pollution has caused toxic air in our cities, and farming and logging have wreaked havoc on our forests. Climate change is creating deserts and dead zones, and hunting is driving many species to the brink of extinction.
This is the first time in Earth's history that a single species - humanity - has brought such disaster upon the natural world. But if we don't look after nature, nature can't look after us. We must act on scientific evidence, we must act together, and we must act now. For many, the Natural History Museum is a place that inspires learning, gives purpose and provides hope. People tell us they 'still get shivers walking through the front door', and thank us for inspiring the next generation of scientists.
To reverse the damage we've done and protect the future, we need the knowledge that comes from scientific discovery. Understanding and protecting life on our planet is the greatest scientific challenge of our age. And you can help. We are a charity and we rely on your support. No matter the size, every gift to the Museum is critical to our scientists' work in understanding and protecting the natural world.
Thank you. Find out more about life underwater and read about the pioneering work of the Museum's marine scientists. Research on communities of killer whales reveals there might be more to menopause than simply old age.

They usually occur in highly social species such as pilot and melon-headed whales. With their herding instinct, the entire group will stay together even if one is sick or compromised, which sometimes causes them to strand while trying to support a distressed individual. To prevent this, rescuers must attend to the stricken animal before refloating the pod.
Toxins build up from the reduced circulation, poisoning the animal. Like other mammals, whales breathe air, so they can drown when stranded if water enters their blowhole at high tide. If you encounter a beached whale, do not attempt to move it. Instead, marine charities, the coast guard, or emergency services can help while you await trained volunteers and veterinarians. Keep the animal upright, wet avoid getting water in its blowhole, and cover it to prevent sunburn.
Still, survival rates are low. Rescue teams will only try to refloat an animal if it is healthy enough to survive. The only other options are taking the animal into captivity—in countries that allow it—or euthanasia. While harrowing, Jarvis argues this is the best welfare decision rather than subjecting a wild animal to captivity. Strandings do help scientists better understand these animals, particularly difficult-to-study species such as beaked whales.
Deaville also points out that strandings can even be a good sign for the species because it can indicate healthier population numbers: Put simply, with more animals out there, more of them are likely to strand from natural causes even if other threats are minimized. All rights reserved.
