whale hunting

This is a happy whale:

This is a sad whale:  









I would like to see all whales like the one in the first picture. But as humans will never be able to make that come true. Because even if we stop whaling there will still be marine parks. 7400 whales are killed every year for their meat and oils. Blue whales and orcas are becoming endargered because of hunting. Long ago humans needed whale meat to survive. Some still do now. But the killing methods became inhumane.
A harpoon is the key tool for hunting whales. It is launched into the animal in order to injure it and eventually bring about its death. This gradual death can go on for lengthy periods of time.
Plz pledge to never help whaling in any way in the comments.
