End of Days
FIRST, A grouse. Why do environmentalists always sound like headmasters ticking off unruly children? And why should a book putting forth a sound argument backed by hard, scientific evidence read like the Old Testament? And bear the title The Revenge of Gaia, like a B-grade thriller?
Other than the author’s writing style — and perhaps the unfortunate lack of a stern editor — this is an excellent book with real potential to shake us out of our collective and individual inertia about the state of the Earth, about what we are doing to it and what it may soon do to us.
An eminent scientist, James Lovelock is well known among Earth scientists and Greens of all hues, and is considered a bit of an eccentric genius. His Gaia hypothesis — that the Earth (Gaia is the Greek goddess of the Earth) is like a self-regulating super-organism whose living and non-living components constantly act and react on each other — is now fairly mainstream. It comprises a critique of, and an advancement over, Darwin’s theory of evolution by factoring the non-living components of the environment into the equation. It is thanks to this synthesis that we understand much more clearly today the links between, for instance, algal growth, cloud formation and global warming.
Lovelock co-authored the Gaia hypothesis while working for Nasa in the Sixties, and has since revised and whetted many of his own and his contemporaries’ insights on environmental evolution. Which is what makes this book such a compelling read. Lovelock is armed with razor-sharp facts to back his argument. We’ve all heard, and queasily shaken off, the argument that our ignorant and callous exploitation of the Earth has pushed Gaia dangerously close to the ‘tipping point’, at which it will no longer be able to support humankind — at least not all 6 billion-plus of us, and certainly not the way we live today. What is harder to come by is a clear, layperson-language description of just how and why this is happening, and the exact scale of the problem. This is what this book provides.
Despite the generally depressing tone of the book, Lovelock holds out hope for delaying, if not averting, this ecological Doomsday. He dismisses ‘sustainable development’ and arguments for renewable sources of energy as misguided, and chastises human hubris in thinking we can ‘manage’ the Earth system. Yet, he himself doesn’t shirk from suggesting a whole gamut of steps to do just that — from practical ones like adopting nuclear and geothermal power to enable a “powered descent” to a stage where we consume lesser energy; to futuristic ones like giant sunshades in space and tiny stratospheric balloons to deflect sunlight; to rather outlandish ones like producing food synthetically like medicines so as to turn all farmland back into forest.
Whether or not one agrees with some of the more dire prognoses and suggested remedies or not, Lovelock does leave one convinced of our own culpability, the folly of the liberal emphasis on exclusively ‘human’ rights, and the need for action. He argues that there is a need to significantly alter not only our lifestyles but also the way we perceive the Earth, to evolve an “instinctive environmentalism”. Only when we begin to perceive ourselves a part of Gaia and empathise with its fate, will we be able to give up such costly luxuries as cheap air travel and central heating/air-conditioning.
So as you shiver under a blanket in your AC room this summer, read this book.
