The final difference is the biggest difference between cows and whales. Cows are raised by farmers in the fields that are surrounded by fences. They don't have any future. And they have to wait their slaughter in the field. On the other hand, whales are free in a huge ocean. They can swim and travel wherever they want. Even though, they are caught by people, other whales have a future. They don't need to wait their slaughter. They have their lives and freedom until caught by people.
