Our global fire crisis is the sign of a dying
biosphere. But we can take action

The unprecedented fires aren’t just caused by the
climate crisis. Land use –especially real estate and animal husbandry – have a
lot to answer for

A good, natural fire can be a cleansing force. Yet,
the recent and ongoing catastrophic fires around the world – including in
Brazil, the US, Sweden, Russia and Australia – are not moments of a healthy
fire cycle but conflagrations of a dying biosphere.
Terrible as
they are, the fires in the western American states are only middling on a
global scale. As of early November, 8.6m acres (3.5m hectares) had burned
nationally, with half of that total in California. This year has been the worst
fire season on record for Colorado and California, the latter enduring five of
its six largest fires since colonization. But the American catastrophe pales in
comparison to Australia’s wildfires last summer, which incinerated an
eye-watering 46m acres. More than a fifth of the country’s forests were
destroyed in a single year. Siberia’s fires in 2020 were even bigger – 47m
acres. A tenth of South America’s largest wetland, the Pantanal, went up in
smoke this year – some 6m acres – coupled with the Amazon losing 8.5m acres.
That latter figure is only half the size of last year’s fiery nightmare.
These
unnatural wildfires may offer few ecological benefits, but they clear out the
deadwood clogging up the public sphere. It is commonly understood that the
recent fires are linked to climate change, but that is only half right.
“Land-use change” is a cause of similar importance, yet it takes up little
space in our public sphere. While the center and left may congratulate
themselves that they “get” climate change unlike the pig-headed right, no
political faction has mobilized around this second great disaster.
The recent
fires each have local idiosyncrasies, such as the Brazilian government’s
murderous attack on indigenous people or California’s trillion-dollar real
estate industry, but a global perspective helps one see why things became awful
everywhere. Climate change can reduce precipitation and warm the air, a
combination that dries out soils and trees in some ecosystems like California,
turning forests into kindling awaiting a spark. Such processes are aggravated
by the jump in deforestation globally since the 1990s. The end of history seems
to have heralded the end of forests too. For example, most clearcutting of the
Amazon has happened since 1990, with almost all of the land replaced with
pasture for cattle. As the world-market finally emerged in the 1990s – an event
predicted nearly a century and a half before by Karl Marx in 1848 – capitalism
swiftly remade heaven and Earth through carbon emissions and land-use change of
unprecedented scope.
Centrists
seem to believe that the fires will convince conservatives that climate change
is real. This has not happened. During a press conference on the fires in
September, Donald Trump claimed that “it’ll start getting cooler”. After the
Arctic tundra caught fire for the first time in 2018, the fascist Sweden
Democrats suggested cutting taxes on gasoline. Conservatives in Australia and
Brazil blamed the fires on non-existent eco-terrorists. Centrists don’t realize
that the solution is not more “facts” but a rebalancing in social forces.
How then
does the left understand this new age of fire? Its foremost theorist on this
issue is the environmental historian Mike Davis. A native Californian, he is
famous for his 1997 polemic The Case for Letting Malibu Burn, in which he
attacked the government for turning a blind eye towards Los Angeles slumlords
flouting fire regulations while frittering away millions to defend mansions in
Malibu – an ecosystem that inevitably burns. Two decades later in 2019, he
contrasted the ashes of Paradise, an exurban working-class town of the elderly
and disabled, to the wealthy enclave of Calabasas, where private firefighters
are becoming a “status symbol for hill-dwelling celebrities”. Davis’s critique
of California’s insane housing market has only become more acute over time.
Since 2000, half of all new residential construction in California has taken
place in the exurbs; rising prices have forced more and more people to live
surrounded by bone-dry forest with few evacuation routes.
As arsonist
ranchers in Brazil make clear, animal husbandry is part of the problem too.
Ranching is the main driver of deforestation in Australia. Deforestation not
only leaves plenty of combustible material about, but it also dries out the
remaining trees because forests create their own microclimate by releasing
water vapor. Even the green giant of the Amazon might shrink to the point where
it cannot sustain its cloud cover and degenerate into a savanna.
California
too falls under “livestock’s long shadow”. Davis and other experts emphasize
how “cheatgrass”, a highly invasive and combustible plant, aggravates
wildfires. In his telling, cheatgrass is an effect without a cause, but even
the US Department of Agriculture concedes the botanical scourge spreads thanks
to overgrazing. And there is plenty of overgrazing in California. It is not
Wisconsin but the Golden State that is “America’s dairyland”, a position it
holds because of the willingness to dedicate 60% of the vast state to
rangeland. Through thirsty fodder crops like alfalfa, the dairy industry
guzzles more water than 40 million Californians.
Governor
Gavin Newsom has announced a raft of measures as a response to the fires in
California that deals with both the earthy and aerial aspects of the
environmental crisis: a ban on new petrol-fuelled cars by 2035 and the mandate
to preserve 30% of California’s land and coastal waters by 2030. These measures
complement the state’s existing commitment to cut its greenhouse gas emissions
by 40% relative to its 1990 level by 2030. While these goals are laudable,
Newsom pretends that they will not conflict with the livestock industry’s
interests. Yet, even big dairy’s in-house scientists scoff at the “cowpie in
the sky” goal of cutting emissions by 40%.
While
California has met its target of reducing 2020 emissions to 1990 levels, mainly
through expanding its renewable energy infrastructure, full decarbonization
will require painful political confrontation. There are lots of low-hanging
fruit left, but they won’t get us all the way to the IPCC 1.5-degree goal. As
long as the power stays on, everyone can get behind solar panels and wind
turbines. But limiting climate change to 1.5C and averting mass extinction – by
shrinking the livestock industry and making what even the apolitical IPCC calls
“rapid, far-reaching and unprecedented changes in all aspects of society” –
make the conflict that centrists like Newsom seek to avoid all but inevitable.
The
solution to the wildfire problem is clear enough, and socialist critics like
Davis are on the right track to criticize the cult of home ownership. Centrists
should be given credit for pushing forward a renewable-energy transition. Yet,
the environmental crisis cannot be fully overcome without a clear-eyed look at
the land-use problem – and serious consideration over whether animal husbandry
is worth its outsized environmental costs.
Californians
like to pride themselves that the future happens there first. Indeed, it isn’t
too late to remake heaven and Earth once more, decarbonizing the sky and
rewilding the land to create a more biodiverse and environmentally stable
society. Without its bloated livestock industry, California could vanquish
cheatgrass, sequester tons of carbon in healthier ecosystems, and liberate
dammed rivers. In this rewilded ecosystem, beavers – yes, California has
beavers – could reclaim their old territory, acting once again as nature’s
humble engineers. Wetlands, many sustained by beaver dams, act as a fire break
and refuge for forest creatures during a blaze. (Indeed, mega-fires may be
sparking local extinction events). Many of these lessons apply to other
fire-racked regions of the world, from the Amazon to Australia. But first,
there needs to be a political coalition that recognizes what fuels these fires
in the first place.
