When did humans start killing whales? Why kill whales? Does it have any treasures on its body?

The history of human killing whales should be long. Since ancient times, fishermen by the sea have killed whales, because whales are full of treasures and have important economic value. Its huge body provides people with a lot of whale meat, whale oil and other products. The Inuit people living near the Arctic Circle have a long tradition of killing whales, mainly to solve the source of food and vitamins. They mainly kill narwhals, and the number is very small. With the development of modern technology, the number of whales killed in Japan is relatively large, which poses a serious threat to the survival of some whale species. In the name of scientific research, Japanese whaling is actually more of an economic benefit.
