"The Koala is, to all intents and purposes, already extinct.
The Australian Koala Foundation has confirmed that, with only 80,000 members of the species left in the wild there isn’t enough to support a new generation.
They’ve declared the marsupial ‘functionally extinct’ which means the population has dropped so low it no longer has any effect on its surrounding environment. Koalas have too few breeding adults left to support the species and any kind of genetic disease or pathogen would put the final nail in the coffin.
Koalas are dying out due to effects caused by climate change."
