After spending more than 20 years reading hundreds of books
describing various aspects of the Earth Crisis, The Future Eaters by Tim Flannery
stands out. It provides a sliver of hope
for the future that is not built on magical thinking. Flannery is a lad who is madly in love with the
Australian region, and he dreams that it will eventually heal, far down the
road someday.
Here’s the story. Hominids
evolved in Africa, and later migrated into Eurasia, where they lived in some
regions for a million years before Homo
sapiens drifted in. In ecosystems where
the fauna coevolved with hominids, the critters clearly understood that two-legs
were predators, and they behaved accordingly.
But when Homo
sapiens first appeared in Australia, none of the critters had ever
seen a two-leg before, so they had no fear.
The fearless elephant seals on King Island weighed up to four
tons. They would calmly sun themselves
while humans killed the animal sitting beside them. On Kangaroo Island, men could walk up to fearless
kangaroos and dispatch them with clubs. Millions
of birds were killed with sticks. Flannery
referred to these hunters as future eaters.
Future eaters were Homo
sapiens that migrated into lands where the ecosystem had not
coevolved with hominids. Australians
were the first future eaters, but far from the last.
The first phase of future eating was to hunt like there’s no
tomorrow. For example, New Zealand was
loaded with birds. Moas were
ostrich-like birds that could grow to 10 feet (3 m) tall, and weigh 550 pounds
(250 kg). Future eaters arrived between
800 and 1,000 years ago, and by 400 years ago the moas were extinct. Today we have found many collections of moa
bones, some containing the remains of up to 90,000 birds. Evidence suggests that a third of the meat
was tossed away to rot. Obviously, the
birds were super-abundant and super-easy to kill.
Meanwhile, well-fed future eaters gave birth to growing
numbers of baby future eaters. More
killers + less prey = trouble. The party
got ugly. Friendly neighbors became
mortal enemies. Moas disappeared from
the menu, and were replaced by Moe and Mona from a nearby village. Cannibalism beats starvation. Overhunting and overbreeding, followed by
bloody social breakdown, was a normal pattern in the world of the future
eaters.
Following the crash, the survivors had two options: learn
from their mistakes, or fool around with new mistakes. The New Zealanders didn’t have time to get
their act together before they were discovered by palefaces. It was a different story in New Caledonia,
where the future eaters arrived 3,500 years ago. They partied hard, crashed, did the warfare
thing, adapted to their damaged ecosystem, and were having a nice time when
Captain Cook washed up on shore.
Future eating contributed to extinctions. In Australia, large animals were going
extinct by 35,000 years ago. Most
megafauna in the Americas vanished 11,000 years ago. In New Caledonia, it was 3,500 years
ago. In recently settled New Zealand,
big animals went extinct 500 to 800 years ago.
In Africa, Asia, and Europe, some megafauna managed to
survive, because of coevolution. The
unlucky ones were domesticated, which led to radical changes in our way of life. Enslaved horses facilitated the bloody spread
of the Indo-European culture from Ireland to India. Along with oxen, horses enabled the expansion
of soil mining. Vast forests were
eliminated to make room for growing herds of hooved locusts.
Australia is an unusual continent. It has been geologically static for 60
million years. Most of the soil is
extremely old, and very low in nutrients.
Consequently, the fauna that won the evolution sweepstakes were energy
efficient, majoring in marsupials and reptiles.
On other continents, soils often contain twice as much
phosphate and nitrates. Lands having
rich soils produced energy-guzzling ecosystems, including large numbers of
megafauna. The most energy-intensive
species of all are warm-blooded carnivores like us. Europe has 660 million people, and Australia
has 17 million.
In addition to feeble soils, Australia has spooky weather,
driven by the El NiƱo Southern Oscillation (ENSO). The climate unpredictably swings between
droughts and floods. Droughts can last
for many years, and then be washed away with a deluge. These freaky swings encourage cautious
lifestyles, weed out energy-guzzling species, and make agriculture especially
unreliable.
Flannery wonders if it’s moral to “live as a vegetarian in
Australia, destroying seven kilograms of irreplaceable soil, upon which
everything depends, for each kilogram of bread we consume?” This question is relevant in all lands. There is no free lunch in farm country.
Anyway, before humans arrived in the Australian region, the
ecosystems were self-sustaining. Then
came the future eaters. Extinctions
included species that had performed essential ecosystem functions, like
controlling woody brush. When brush got
out of control, it reduced grazing land for herbivores, and encouraged
devastating wildfires.
To reduce this new imbalance, Aborigines periodically lit
fires to keep the fuel from accumulating.
Unfortunately, during burns, soil nutrients went up in smoke, especially
nitrogen. Exposed soils were vulnerable
to wind erosion. The land got
drier. Centuries of burning produced a
downward spiral that was largely irreversible.
There was no undo command.
The hunters must have had turbulent times as the initial era
of plenty and prosperity dissolved into scarcity. Then, “for 60,000 years Aborigines managed
the crippled ecosystems, preventing them from degenerating further.” For the last 12,000 years, surviving evidence
suggests that they lived in a stable and sustainable manner. They succeeded at this by learning the most
important trick of all — adapting to their ecosystem. They were forced to return their future eater
badges and uniforms, and they were glad to do so.
Meanwhile, back in Eurasia, the nutrient rich soils were sprouting
the biggest and craziest mob of future eaters to ever walk the Earth. For the last 12,000 years, they have exploded
in number, exterminated the megafauna, laid waste to forests and fisheries, and
spilled oceans of blood. Then, they discovered
Australia, and imported the future eater mindset, with predictable results.
Today, the human population of the planet is almost entirely
future eaters. Our binge of plenty and
prosperity is wheezing, bleeding, and staggering. Climate change and the end of cheap and
abundant energy will derail civilization as we know it. We are proceeding into an era of scarcity and
conflict. When the smoke eventually
clears, we would be wise to learn the most important trick of all.
On the plus side, we are the first future eaters to
comprehend the catastrophic effects of our future eating lifestyle. It’s never too late to learn, think, and grow. There’s never been a better time to question
everything. In a thousand years, if we
make it, we may be asked to return our badges and uniforms. There is hope! Hooray!
