Australia's fires have already killed 1 billion animals—unpacking the tragedy through statistics

Fire has been a crucial part of Australia’s ecosystem for millennia. Many species in the nation’s forests and deserts are purposefully flammable, relying on regular, mid-sized burns to manage plant and animal diversity. Aboriginal tribes such as the Martu lit controlled fires that shaped their ecosystems; modern conservation groups are bringing these methods back today.

But Australia’s 2019-2020 fire season has been anything but controlled. In late June 2019, high temperatures and drought enabled blazes in the northeastern state of Queensland, which doesn’t see its fire season typically begin until August. By September, fires were raging in New South Wales. Gladys Berejiklian, the state’s Premier, declared a state of emergency two months later; hundreds of schools were closed and thousands were evacuated as over 60 fires burned across the region.

As of February 2020, many fires remain uncontained across eastern Australia. Millions of acres of wilderness have been destroyed, thousands of homes and buildings have been destroyed, and over 1 billion local animals have been killed. According to Robinson Meyer, a climate reporter for The Atlantic: “Over the past six months, Australian fires have burned more than twice the area than was consumed, combined, by California’s 2018 fires and the Amazon’s 2019 fires.” Meanwhile, the country’s federal government lags many other nations on climate policy, and Prime Minister Scott Morrison denies a link between bushfire severity and climate change.

To demonstrate the scale of this environmental crisis, Stacker scoured news reports on Australia’s fires from the past six months, and research by nonprofit groups such as Global Forest Watch, to identify 15 key statistics on the environmental damage caused by these fires, as well as the political legacy they are leaving. If you would like to contribute to recovery efforts, both firefighting organizations such as the New South Wales Rural Fire Service and wildlife organizations such as WIRES are soliciting donations.

27 million acres of wilderness destroyed

Since September, about 27 million acres (11 million hectares) have been devastated by the fires—that’s an area larger than the size of Austria, or one-third the size of Germany. The fires have impacted Australian habitats from deserts to rainforests, threatening a diverse range of people and wildlife.

Over 1 billion animals killed in the fires

Prof. Chris Dickman of the University of Sydney estimated in January that over 1 billion animals have been killed in the bushfires. 800 million of those estimated deaths were in New South Wales, a southeastern province that is home to koalas, kangaroos, platypuses, and other endangered species. Prof. Dickman’s calculations are based on a 2007 World Wide Fund for Nature study which analyzed the impacts of land clearing in New South Wales.

“I think there's nothing quite to compare with the devastation that's going on over such a large area so quickly,” Prof. Dickman said of this year’s fires in an interview with NPR. Many animals which try to escape the blaze end up in ecosystems that do not have the resources they need, or fall prey to predators.

70% of fires burning in forests

According to Global Forest Watch Fires, an online platform by the World Resources Institute that monitors forest destruction, over 70% of the Australian bushfires have raged through the nation’s forests. Many of these forests are comprised of Eucalyptus trees, plants which are both a key food and shelter source for Australia’s unique animals (such as koalas) and hold cultural significance for the nation’s indigenous people. These trees are more naturally flammable than many other species, and the speed and duration of these recent bushfires have prevented Eucalyptus forests from recovering.

40% of fires burning in legally protected areas

Almost one-fifth of Australia’s land is federally protected by the country’s National Reserve System. This land includes forests storing about 1.65 billion U.S. tons (1.5 billion metric tons) of carbon, and is carefully managed to keep that carbon in the ground to prevent further carbon dioxide emissions—or at least, it would be managed if the forest were not on fire.

These protected areas on fire also include many of Australia’s “Alliance for Zero Extinction” sites, regions which are the sole habitats for endangered species that only live in Australia. Fires in these areas threaten unique species such as the Wollemi pine tree and Corroboree frog.

2,000 houses destroyed in New South Wales

New South Wales is the most populous state in Australia, home to about 8 million people—that’s almost the population of New York City (8.5 million). Fire has impacted over 12.3 million acres (5 million hectares) in this region, according to the BBC; more than 2,000 households have been destroyed and thousands more have been forced to evacuate. More than 1,600 New South Wales firefighters, many of them volunteers, are currently working to slow the blaze.

Sydney air in November equivalent to smoking 32 cigarettes

Almost two-thirds of the New South Wales population lives in greater Sydney, the nation’s largest city, which has been hard hit by the fires. This past November, Brian Oliver, a professor specializing in respiratory diseases at the Sydney University of Technology, estimated that simply inhaling the air in Sydney’s fire haze areas had the equivalent health impact of smoking 32 cigarettes. Prof. Oliver told “Walking out into and inhaling the current pollution could cause heart inflammation and trigger a cardiac arrest.”

4,000 people trapped in seaside town Mallacoota

Perhaps the most devastating images from these bushfires so far came from Mallacoota, a small southeastern town and tourist destination with 1,000 year-round residents. About 4,000 people were forced to evacuate by air and sea when winds pushed fires toward the town. Eyewitness accounts of the town show unnerving red skies, widespread destruction of homes and buildings, and rescue services unprepared to handle the catastrophe.

Bushfire smoke traveled 7,000 miles

Besides uprooting Australian people and wildlife, the bushfires have pushed a plume of smoke about the size of the continental United States across the globe. This smoke contains vast amounts of carbon dioxide which will further damage the atmosphere that enabled the fires in the first place. Dr. Pep Canadell, an Australian climate scientist and executive director of the Global Carbon Project, estimates that fires in Australia’s southeast have emitted about 400 million tons of carbon; this is more than two-thirds the emissions that man-made sources in Australia sent up in the entirety of 2019.

The smoke plume has traveled 7,000 miles across the southern hemisphere so far, according to satellite images released by NASA. It had hit Chile and Argentina by the beginning of January, and could reach the Atlantic basin depending on wind conditions.

25,000 koalas killed on Kangaroo Island

Kangaroo Island, Australia’s third-largest island off the coast of Adelaide, is home to protected animals such as kangaroos, wallabies, echidnas, platypuses, cockatoos, and koalas. Fires have devastated all eight sites protected by the Kangaroo Island Land for Wildlife organization and slashed animal populations, including koalas: 25,000 of the island’s 50,000 koala population are estimated dead.

“People call this place a little Noah’s Ark,” Land for Wildlife ecologist Heidi Groffen told the Guardian. “The island is a refuge. This is the largest fire we have seen in a long time.”

Australia ranks #56 of 61 countries on climate policy

The past few months’ bushfires have called attention to a severe lack of environmental action on the part of Australia’s federal government. The Climate Change Performance Index, a research partnership between the research groups Germanwatch, the NewClimate Institute, and the Climate Action Network, ranked Australia #56 out of 61 nations on their 2020 list.

According to the country’s rating page, the Australian government has not proposed renewable energy targets beyond 2020 and continues to promote fossil fuels. In June 2019, for example, the government approved the Adani coal mine, a project that will severely threaten the already endangered Great Barrier Reef.

300,000 Australian students strike for climate in September

Students across over 100 Australian cities and towns left school to rally for climate justice on Friday, Sep. 20 as part of an international week of action. The strikes included about 100,000 students in Melbourne and 80,000 in Sydney, organizers estimated; the Guardian called this Australia’s largest public demonstrations since anti-Iraq War marches in 2003. Students at the rallies spoke about the steps needed to ensure a future for Australia, and called directly on Prime Minister Scott Morrison (or “SCOMO,” as he was called on signs) to take action.

18 warnings ignored by Australia government since 2013

In November 2019, about two months into the bushfire crisis, Prime Minister Scott Morrison claimed that there was “no direct link” from greenhouse gas emissions to fire severity. In response, however, David Ritter, CEO of Greenpeace Australia Pacific, outlined 18 instances between 2013 and 2019 in which Australia’s climate experts warned their political leaders about how global warming exacerbates bushfires.

In the most recent warning included in Ritter’s viral Twitter thread, several Australian climate scientists cited the fires’ drastic conditions as a “direct result” of global warming and called on the government to act accordingly. “What climate change does is exacerbate the conditions in which the bushfires happen,” said Dr. Imran Ahmed of Australian National University.

Economic cost to Australia could be $3.4 billion

Economists cited in Reuters estimated that the bushfire crisis could cost Australia up to $3.4 billion (Australia $5 billion). The fires have devastated the nation’s east coast during peak seasons for both tourism and agriculture.

For example, the dairy industry—the country’s fourth-largest rural industry—has been hit along New South Wales’ coast. Bushfire damage has piled onto farms already facing a three-year drought. Paul Mumford, a dairy farmer quoted by Reuters, said that “Many roads are closed,” preventing farmers from reaching help, and that the fires “have primarily killed the youngest in the herd."

$32 million raised by comedian Celeste Barber

International support in the wake of the wildfires has largely come from celebrities. Celeste Barber, an Australian comedian, writer, and actress, raised $32 billion from over 1.2 million people through Facebook, setting a new fundraising record for the social media platform. Other famous pledgers include pop singer P!nk, Nicole Kidman, Russell Crowe, and Kaylen Ward, an Instagram model from Los Angeles who raised an estimated $500,000 by sending nude photos to donors.

Still, as independent climate reporter Emily Atkin points out in her HEATED newsletter, fossil fuel companies and other corporations that contributed to greenhouse gas emissions have shirked responsibility in financially supporting wildfire relief. Chevron, for example, donated $1 million to the Australian Red Cross—but that $1 million only amounts to about 0.0067% of the company’s annual earnings, the equivalent of an average American donating $4.

20 of 60 New South Wales fires put out by February rain

Torrential rain poured down on Australia’s East Coast in the first week of February. As of Feb. 7, the rain had extinguished 20 of 60 estimated fires in New South Wales, a region which has faced drought for the past three years. Friday, Feb. 7 was Sydney’s wettest day in over 15 months, and firefighters welcomed a well-deserved rest.

The rain came with its own troubles, however, as flash flooding caused landslides and trapped people in cars. New South Wales and Queensland recorded almost 1,000 distress calls over three days. And meanwhile, many large bushfires located further inland continue to burn.
