Pros and Cons of Whaling? What is the purpose of whales?

In the past, whaling was used to obtain industrial raw materials such as whale baleen and whale oil, as it was not possible to produce anything like this at that time. Today, there are already cheaper and better-performing alternatives to these things, and whaling is completely unnecessary. And once a large animal like a whale is killed on a large scale, it is difficult for the population to recover.

So whaling is harmful and not beneficial.

Whales are from the 60s to the 90s. Some countries were severely sentenced, but Japan had the help of the United States so it just stopped whaling, but after a few years it started again. Some say that there are only 945 left in the world.

Murder for money, extinction of species, inhumaneness, and loss of children and grandchildren will be punished.

The benefits of whaling are many, but the disadvantages are unknown.

Yes, wow, I have what you want, and there are a lot of them in it, and you can see me all if you need them. See my homepage. to learn about whaling.

Depending on the species, baleen whales have two different methods of predation.

Degreasing: Beluga whales, like beluga, filter plankton as they swim slowly, with their mouths ajar and water flowing in from the commissure.

Feeding: When this whale approaches a large pool of shrimp on the bottom of the sea, it opens its mouth wide and swallows a large amount of water, which is packed into an extended, folded belly. When the mouth is closed, the whale's tongue reels in the water filtered by the whale's tooth plates. For example, blue whales can swallow 25,000 liters of water at a time.

Every year, some whales leave the food-rich polar oceans in search of warmer waters in order to have offspring. They travel thousands of kilometers over a period of several months in a very certain period. Every winter, many visitors sail thousands of miles to encounter them in the Hawaiian Sea and the Gulf of Mexico.

In the case of sperm whales, males are not allowed to migrate because there is not enough food for the squid in the breeding area.

Open your mouth wide and suck in both food and water.

The whale opens its mouth wide in the sea and swallows many small fish and shrimp into its mouth along with the seawater, and then closes its eyes to filter the seawater out of the filter plate, and swallows the small fish and shrimp into its stomach.

Whales are a class of large marine mammals that belong to the order Cetaceans. They play an important role in the ecosystem. Here are some of the main purposes of whales:

Control plankton populations: Whales are the main predators of plankton, and they control their populations by filterfeeding or preying on small fish and crustacean motives. This helps to maintain the balance of the marine food chain.

Transporting nutrients: Whales ingest large amounts of nutrients when they forage and then take these nutrients to other areas. Their droppings are rich in nutrients and can promote the growth of phytoplankton and provide food for other marine life**.

Promotes ocean circulation: Whale cheating carries a large amount of water as it migrates, which helps to promote ocean circulation and mixing, distributing oxygen- and nutrient-rich water bodies over a wider area.

Tourism and viewing value: Whales also have great tourism and viewing value. People enjoy watching whales swim spectacularly and jump out of the water, which has also become an important tourist activity.

It is important to note that whales have been threatened by overhunting and habitat destruction in the past, so protecting whales and their habitats is essential to maintain the balance of marine ecosystems.

Whales are large mammals, they cannot reproduce in large numbers as quickly as fish, but like humans, they need to be fed milk and raise their young, so the whale population grows very slowly. For a long time, over-whaling in a few countries has put cetaceans at risk of extinction.

In this context, the International Whaling Commission (IWC) issued a ban on commercial whaling in 1982 and adopted the Global Whaling Ban Convention in 1986. Every year, Japan slaughters thousands of whales in the Southern Ocean, the last remaining habitat for cetaceans, and some populations are already on the verge of extinction.

China Incident: China has historically seen very little whaling. In the Qing Dynasty's "Cantonese Xinyu", it was recorded that the whaling method of "tying a spear with a long rope and flying stabbing it" was only a hunt for nearshore cetaceans.

In the 50s of the 20th century, there were a small number of operations in the inner bay and offshore. Cetacean hunting has been completely stopped since 1981. In the late 17th and 19th centuries, China hunted whales off the coast of Guangdong Province.

In 1953, coastal whaling was carried out in the port of Wotou in Huiyang, the province. In 1955 and 1958, Luda Aquatic Products Company tried to catch small whales in the northern part of the Yellow Sea, and the fin whales were successful. In December 1963, the whaling ship "Yuanlong", which was designed and built by itself, was put into trial production, and the operation was stopped in 1978.

Taiwan Province began whaling in 1957. In 1981, China stopped whaling altogether.

1. Whale meat accounts for about half of the whale's body weight, in addition to grinding into coarse powder as feed or fertilizer, it can also be used for human consumption after processing.

2. Blublem is an animal oil rich in fat. It not only contains a large amount of glycerin, which can be used to synthesize nitroglycerin in explosives and paper cigarette processing, but also can be used to make soap and refine high-grade lubricants.

3. Whale feces and bone meal are fertilizers rich in ammonia and phosphorus.

4. The texture of whale skin is soft and the surface is superficial. It has fluff and leather with patterns, which is suitable for making clothes or leather bags.

5. Bone glue can also be extracted from whalebone, which can be used as a raw material for processing photographic film.

6. Whale liver is very rich in vitamins A and D. The liver of a sperm whale often weighs 400 kilograms, and its content of alpha vitamins is equivalent to that of 100 tons of high-quality cream or 5 million eggs.

7. Baleen and whale teeth can be processed into medical equipment or handicrafts.

8. Whale fins can be used as umbrella surfaces, bow ties and cigarette cases.

9. The ovaries of whales are also the raw materials of progesterone (especially progesterone) for a special drug called "progetine".
