Cruelty to the whales in Japan

I think that the ministry need to put a stop to the cruelty of whales. Whales are hit not on their brains but on other parts of the body, making them suffer for 30 minutes before dying. The sea will also be pollute with blood, making it seems disgusting. Furthermore, if humans keep on hunting whales, they may become endangered and would soon be wipe out. If the government wants to do research on the whales, they should not kill too much whales but do it in moderation. But i think it is best that the whaling as it is unhumane. Hope that all of you can help stop the hunting of whales.
