Reviving the Tazmanian Tiger
The Tazmanian Tiger
Once Europeans reached Australia they had a bounty to kill all of the Tazmanian Tigers because they were a danger to farm animals. That was one of the many things to make them go extinct. Another thing was that the Europeans also brought the Exotic Dingo along with them which caused them to have competition for food.
When they went extinct, there weren't laws like we have now. Even though tigers in India are a danger to farm animals they are protected. Some of them are still killed for their bones but they are surviving. If the Tazmanian Tiger was revived now it would survive because it would be protected from hunters.
