Transcript for Australian wildfires pose serious threat to koala population
We move on to the deadly destroying millions of acres and wildfires in Australia threatening the koala population. Hundreds of them have died in this unprecedented outbreak and more have lost their habitats. Reporter: Wildfires are threatening to wipe them out all together. They're a national pressure but this morning the fate of Australia's koala population is hanging in the balance as deadly fires continue to rage across the country. The chairman of the Australian koala foundation estimates that over 1,000 koalas have been killed from fires and over 80% of their habitat has been destroyed, days after this rescue was caught on camera. You can see the woman wrapping the koala in her shirt and carrying it to safety. I knew that if we didn't get him down from the tree, then he would have been up there amongst the flames.

What's left is so dry that they're not getting nutrients. Reporter: Many have urged the koala protection act. Now thousands have joined the cause. One hospital raised six times their original goal of $25,000, now surpassing $1.5 million. The bush is going to take a long time to recover so these animals might be in our care for much, much longer. Now, you may have seen a headline that went viral saying koalas were functionally extinct. It was refer to the ongoing loss of their natural habitat.

We're going to turn now to who data nation.
