Visions
of planet-wide disaster dance through our culture these days. Thanks to scientists,
journalists and Al Gore, we know more than ever about the ecological, economic
and political stresses we're placing on the world. Novelists and filmmakers are
fond of foretelling a complete breakdown of social order, whether through spectacular
catastrophe or slow attrition, that leaves the remnants of humankind scrabbling
viciously for whatever paltry resources are left.
Even
in most apocalypse scenarios – such as Cormac McCarthy's Oprah-touted blockbuster
The Road – the concern is life for the human survivors. We apparently consider
the prospect of the Earth enduring after our extinction as inconceivable or irrelevant.
Not
Alan Weisman. With The World Without Us, the American science journalist has written
an entire book about what a post-human Earth might look like. It's an intriguing,
attention-grabbing premise – albeit a strictly hypothetical one in this case.
Weisman imagines the human race disappearing more or less overnight, leaving the
rest of the global ecosystem in the very same shape it's in now, unravaged by,
say, the fallout of a nuclear war. Barring some supernatural rapture, that's unlikely
to ever happen: If we all go at once, it probably won't be quietly or unobtrusively.
Even a deadly new species-wide disease, for example, would still leave some survivors
to carry on, as Weisman notes late in the book.
Still,
the abstract premise makes an excellent springboard for an often fascinating look
at our planet's biology and ecology. On its most basic level, The World Without
Us appeals to sheer curiosity about what kind of record we'll leave of ourselves,
and how long it will last. Individual homes will go quickly, as untended roofs
collapse within decades and moisture attacks from within. Skyscrapers and bridges
will fall after a few centuries, returning cities to their original forest or
jungle states. (We can forget all about those sci-fi imaginings of perfectly preserved
underwater downtowns, à la Steven Spielberg's Artificial Intelligence.)
Posterity
will be better served by underground dwellings, like the cavernous multi-level
cities discovered at Cappadocia, Turkey, which date back 10,000 years. Mount Rushmore
should last for 72,000 years or so – likely long after anyone's around who
will be able to recognize its faces – and copper-based sculptures like the
Statue of Liberty could hang on practically indefinitely.
Weisman's
MO is to zero in on specifics. He looks closely at the fate of Manhattan, for
example, but says very little in general about which metropolis might outlast
others. And he offers no cohesive single-chapter overview of the world's fate,
which means that readers should not come to The World Without Us expecting much
of a synthesis or unifying narrative. The book feels like it's all tangents and
little centre. Weisman's prose is often dry, and the author is not a storyteller;
the strengths of this book are the breadth of his research and his gift for presenting
a huge array of information clearly and quickly.
This
is enough. Those tangents are usually fascinating, whether they cover the engineering
of the Panama Canal or speculations about the fall of the Mayan empire or descriptions
of the long-gone giant animals that roamed the prehistoric Americas. There's something
exhilarating about skipping from a Turkish resort strip left eerily abandoned
after a war to the gigantic industrial oil complex of the Houston area.
There
is one notable recurring motif in the book: our ugly chemical and nuclear legacy.
Besides the 400-plus active reactors ready to spew radioactivity into the environment
if left without maintenance, there are underground caches of nuclear waste that
could make nasty surprises for unsuspecting future visitors. Tiny airborne particles
of plastic have already entered the food chain at many levels, which could affect
the future evolution of other species in hard-to-predict ways.
"What
will survive of us is love," wrote the poet Philip Larkin, but what will
really survive of us, it turns out, are polymers.
The
World Without Us doesn't read like a primarily environmentalist text. Weisman's
tone throughout is cool and dispassionate, that of a scientific observer rather
than an activist. When he does argue that we should take care of our planet, it's
in basic terms that are nigh impossible to dispute. Nor does he celebrate or advocate
the end of our existence – though he does give some space to the Voluntary
Human Extinction Movement, which argues that the best thing for the Earth and
for us would be human-wide sterility. Founder Les Knight gets a little dreamy
as he suggests that our final generation would live in an idyllic paradise marked
by less competition for resources. (Apparently he never saw Children of Men.)
The
flip side to Weisman's dispassion is that The World Without Us is a book of facts
more than ideas; it's rarely illumined by the philosophy or poetry that its premise
would seem to invite. The closest it comes is a chapter that covers some of our
poignant efforts to send a sort of cultural time capsule into outer space. The
Voyager space probes contain gold-plated disks bearing images and sounds that
represent human life, including musical selections ranging from Mozart to tribal
rhythms to Louis Armstrong.
Long
after the very Earth has been swallowed by the sun, Voyager and its cargo –
"the last remaining fragments of human aesthetic expression," in Weisman's
words – should still be travelling. The broadcast waves we've been sending
into space for the past 100 years will also keep on marching indefinitely; it's
not inconceivable, says Weisman, that some extraterrestrial intelligence will
one day encounter I Love Lucy. "They may not understand Lucy, but they will
hear us laugh."
