The Tasmanian Devil is a magnificent animal. It is an endangered animal. It became extinct from the mainland about 600 years ago, due to the arrival of the aboriginals the indigenous people of Australia and the dingos, the arrival of the white people also made a big dint in the devil's populations after the white people brought foxes to Australia. The only place where the dingos and foxes have not conquered is Tasmania. But now, the devils could be gone, never to return by 2015, due to the founding of foxes in Tasmania a few months ago.
The government of Tasmania have agreed to inject a vaccine into the foxes in Tasmania, the vaccine is call immunocontraception. The vaccine tries to convince the immune system to believe that spern and eggs are unwanted invaders, then that will prevent fertilisation.
