Fires in Australia, 1 billion animals dead, since Sept. 2019.
Part of Australia has been devastated by the flames since September 2019. A billion animals are said to have perished in the flames.

Dehydrated koalas, kangaroos trapped in the flames. In the states of New South Wales and Victoria, more than 5 million hectares have gone up in smoke, almost twice the area of Belgium. An Australian study indicates that 800 million wild animals have died in these two states. At the national level, the bar of one billion dead animals would be crossed.
Where does this number of one billion dead animals come from?
This number comes from the study of an Australian researcher from the University of Sydney, Chris thingyman. This scientist is based on one of his 2007 reports on deforestation.
According to this work, 160 animals live on one hectare. Chris thingyman establishes that at the time 640,000 hectares were burned, and 104 million animals perished.
The researcher then performs a rule of three. Since the start of the fires,
5 million hectares burned - twice the size of Belgium, so 800 million animals died.
'' If the death rate does not reach 100%, it should approach it.
Chris thingyman, professor of ecology at the University of Sydney ''
"The habitats destroyed in 2007 are the same as the ones that are currently burning," says Chris thingyman. "So we can expect the density of animals per hectare to be almost the same today as in 2007," said the professor of ecology.
"If the death rate does not reach 100%, it should approach it", concludes Chris thingyman.
Which animals are included in this study?
Of the 800 million dead animals, all mammals, such as koalas and kangaroos, are included. Birds and reptiles are too.
In contrast, this study does not include bats, frogs, fish, or insects.
This number concerns two states: New South Wales and Victoria.
Nationally, according to Professor Chris thingyman, the mark of a billion animals dead since the start of the fires is surpassed.
These figures are fairly solid [...] in their order of magnitude.

Franck Courchamp, director of research at the National Center for Scientific Research (CNRS) and at Paris-Saclay University believes that these figures are "fairly solid [...] in their order of magnitude".
Since "we know how many animals were there and how many hectares were burned," he continues, "we can easily calculate how many animals were present in all the places that burned."
How many koalas died in the fires?
Between 8 and 10,000 koalas died in three months. This number is equivalent to a third of the world's population: the koala only lives in Australia.
The number of dead animals could increase: in the face of drought, Australian authorities plan to kill 10,000 wild camels.
