Australia has been burning since September and an end to the catastrophic destruction does not appear to be in sight. Officials believe the fires could take months to extinguish.
The wildfires have already claimed more than two dozen lives and destroyed over 2,000 homes, according to The Associated Press.
Wildlife conservation group WWF in Australia is now also estimating that 1.25 billion animals have died.
As of Wednesday, estimates said as much as 15.6 million acres of land had burned. That's greater than twice the size of Maryland. New South Wales is getting hit the hardest with about 130 fires still burning across the state as of earlier this week.
For the first time in Australian history, thousands of army, navy and air force reservists have been thrown into the fight against the fires. U.S. officials said Tuesday they're planning to send 100 firefighters to the country next week, joining the 159 U.S. firefighters already there.
The fires started several months earlier than is typical for Australia's annual wildfire season as the country suffers through its hottest and driest year on record.
