If upon first reading the title of this book you were
slightly lost, don’t feel alone. At
first I thought it may be something to do with French street artists using
natural camouflage! Luckily, I turned to
the blurb and was immediately fascinated by Janine Benyus’s stimulating and
imaginative book about the possible future of environmental manufacturing/design
and sustainability.
Benyus writes with adventurous prose and genuine enthusiasm
about the potential direction of a series of different products/economy
sectors/holistic systems in a book that, frankly, opened my eyes to a number of
budding marriages between science and nature that had not even crossed my
mind. At times it feels like a science
fiction novel, but the book is incredibly well researched – Benyus interviews
many of the most credible and innovative scientists in each of the respective
fields she writes about – and has a great blend of idealism and pragmatism.
Benyus playfully deconstructs the efforts made by scientists
to mimic nature’s best designs in order to improve functionality and reduce their
impact on the environment with the ‘Holy Grail’ of reaching sustainability (or
even net positive impacts). Just a few
of the ideas that genuinely caught my attention include:
Bio-Computing
Understanding the computing strength of DNA and how this can
be harnessed to radically improve the speed and size of our computers is incredibly
hard to fathom (and I am certain the proceeding explanation will not do it
justice, so please research more on your own if you’re interested). Natural or bio-computing involves completely
divorcing your mind from the idea of computers as man-made, solid (and slow)
objects.
Needless to say that my scientific knowledge isn’t strong
enough to properly boil the process down to a digestible sentence in one blog,
but the basic idea was developed by the head of the of the cutting-edge
BioComputing Group, Michael Conrad, and revolves around harnessing the
processing power of DNA/enzymes/proteins.
To evolve beyond digital computation (a.k.a. linear computation), where
one piece of information is processed at a time using a series of zeros and
ones, to parallel or 3D computation (similar to the brain) in which multiple
networks are connected and exponentially more computations are processed at the
same time, Benyus describes the switch from the world of silicon computing to
carbon computing.
Like conventional computers, DNA takes information,
processes it and passes it along to initiate an action. Protein molecules have specific receptors
that can feel for other shapes, consequently, they are the ultimate pattern
recognisers (which is essentially what conventional computer code is). Were you to hitch together millions of these
proteins you would could create molecules that, when activated by a specific
light frequency, could create a specific shape that interlocks with a corresponding
shape/line of code to create a new sequence/computation. Known as a “tactilizing processor,” these
proteins compute simultaneously and evolve to create smarter and smarter
networks. Consequently, without a single
electric wire, a large number of disparate inputs would be sorted, coded and
translated simultaneously into a coherent answer.
The power of such computing is, I think, not understated in
the following quote, “a DNA computer could perform more operations in a few
days than all the calculations ever made by all the computers ever built.”
The potential of such computing is truly difficult to
comprehend. Not only does it apply to
computation but also storage as, “a million times more information could be
stored at the bottom of a test tube of DNA than in the entire human brain.”
The most modest of early applications includes real-time
facial recognition software that works in any environment, no matter how
crowded or complex (current linear computation struggles with such a task). However, you don’t need to be George Orwell
to think about the repercussions of being able to create extremely powerful
little computers that can fit inside your blood stream!
Natural Fibres
Current methods for producing synthetic materials all
involve serious levels of heating, beating or treating that all inescapably
energy intensive. Yet, in nature, we see
that the spider is able to produce a silk that is five times stronger than
steel without any ovens, machines or chemicals.
Other animals have similarly amazing abilities to produce
materials that man-made materials cannot yet come close to matching. Consider a rhino horn that repairs itself, an
abalone shell that has twice the structural strength of any known ceramic or a
mussel’s adhesive that is completely water resistant and reusable. In addition, all of these animals manage to
produce such results without toxicity.
Consequently, Benyus analyses the efforts being made by
scientists to understand the protein sequences of such materials and how we may
attempt to recreate the conditions in which they are naturally made. Benyus never fails to stimulate the imagination
and provides an exciting insight into how we may soon be seeing products like
synthesised crystal which could be used to manufacture (virtually) unbreakable
windshields.
Solar Energy
Swanson’s Law (similar to Moore’s Law in computer
processing) dictates that the price of solar photovoltaic cells tends to drop 20% for every doubling of industry
capacity. As encouraging as that
may be, Benyus explores how the photosynthetic potential of solar panels can
radically improve by studying the electron transfer in the reaction centre of
photosynthetic cells in different types of leaves. The most revolutionary application of this
research being the ability to create power packs that are activated by sunlight
(meaning you could carry back up power with you to any corner of the globe!).
Natural Medicine
Biomimics across the world are studying primates to see how
they use plants, minerals and bacteria to regulate their digestive system. Surprisingly this has already been the
inspiration for many previous medicines (and even contraceptives) and continues
to provide innovative solutions to the healthcare industry.
It’s hard to know which ideas will prove fruitful and which
will die on the laboratory table, but it’s Benyus’s childlike enthusiasm that
really turns this book from a dry exploration of current scientific trends into
a wonderfully optimistic book about Man’s potential to live harmoniously on
this planet. It’s ‘keen green’ if ever
I’ve read such a thing, but I can’t fault the author for its truly infectious
tones.
Benyus concludes by talking about the different types of
natural systems and I think she draws a powerful parallel in doing so. In nature there are three types of systems:
I.
Type I Systems expand quickly, using all the
resources and filling all available space at the expense of others (and
ultimately their own – as they always eventually collapse). Type I examples include things like ragweed,
crabgrass, viruses and bacteria, etc.
They’re characterised by short-term thinking and opportunism.
II.
Type II Systems attempt to create rooting systems
and will fight their neighbours for the space around them but are not as
voraciously dominant as Type I systems.
They’re characterised by a mixture of medium growth rates with eventual
prudence (such as bushes and seedlings).
III.
Type III Systems grow slowly, plant deep roots
and seek equilibrium with their surroundings.
The quintessential Type III is a redwood tree: patient, seeking
optimisation of resources with no waste and consideration of its neighbours.
It’s obvious where the analogy is heading, but nonetheless a
salient point to make. Humans have for
too long behaved like Type I systems, drawing down on natural resources,
creating waste that is not recycled, maximising rather than optimising and, in
the process, fouling our own nest. All
three systems are necessary to grow a forest, but over time the Type III system
always wins.
I would love for Benyus to update this book, as it was
written in 1997 and is still, in 2013, way ahead of its time. It undoubtedly awoke something in the social
and scientific conscience that we all know to be true: we are not bigger or
better than Mother Nature and we must learn all we can from her or we’ll be
thrown out the classroom.
Score: 84/100
P.S. In researching whether Benyus had updated this book, I
did stumble across a TED Talk that she gave in 2009. It covers some of the material in the book
and a couple of new, updated ideas as well – definitely worth the time if the
above caught your attention.
