It didn't. The last of the thylacines died out before official protection for Australian native wildlife was brought in. The last known specimen died in the Hobart Zoo in 1936. Its needs were not understood and it was believed to have died of exposure.
If they are not protected, they will become extinct.

Yes, the species has become endangered due to lack of vegetation and water, they are currently a protected species.
Bobcats are common animals, and still have hunting seasons on them. Not an endangered species.
Without plants to produce oxygen the human race will become extinct.
the thylacine became "overhunted" meaning that too many people shot/killed this spieces and drove it to extinction.
The striped dolphin is not endangered, but is considered a protected species. That means without a some sort of protection plan in place, the species would become endangered.
All endangered and vulnerable species need to be protected. If not they will become extinct. Each animal plays an important role in biodiversity, so it is our duty as the smarter species to protect those that are endangered.
Threatened animals are ones that are legally listed as susceptible to becoming endangered - the animals are becoming more rare because of attributable factors determined by scientific studies. Species of concern is a species that may sometime in the future become threatened but that requires more study. More information about this is: They are species, populations and ecological communities that are considered by the NSW Scientific Committee to be at risk of extinction in the immediate to medium-term future in NSW. Together this information is described as 'threatened'.
The proper name for the tasmanian wolf if Thylacine. It was also known as a Tasmanian tiger. The Thylacine was niether a wolf nor a tiger, but a marsupial. The last known specimen died in 1936.
Various species are bred in aviaries and zoos across the world and many species are not protected by law, so owning one is definitely possible. As for them being pets, that is a different proposition, but individuals of many species can become tame even when the majority usually do not.
When the last living member of that species dies, the species become "extinct".
