About 10,000 years ago, “as the last ice age ended, a new epoch of global warming called the Holocene began.” In recent years, however, Nobel laureate Paul Crutzen has theorised that we have now entered a new era: the Anthropocene, the Age of Man.
The shift can probably trace its beginnings to the mid 19th century, with the Industrial Revolution, but the true impact of humans on the world has been apparent since World War Two: “driven by population explosion, globalisation, mass production, technological and communications revolutions, improved farming methods and medical advances,” it has become known as The Great Acceleration. “It took 50,000 years for humans to reach a population of 1 billion, but just the last ten years to add the latest billion… Meanwhile, our closest relative, the chimpanzee, is living much as he did 50,000 years ago.”
Where once geology dictated the shifts in climate, landscape and atmosphere, now the responsibility lies with the actions, either intentional or as a side-effect, of humankind. The facts are undeniable. Four tenths of the planet's land surface is used to grow our food. Three-quarters of the world's fresh water is controlled by us. “Man is no longer just another species… We have become the masters of our planet and integral to the destiny of life on Earth.” But as our growing population makes us ever more demanding of the natural resources and processes, the key to future survival will be in how we deal with the consequences of our own impact.
Gaia Vince is a highly regarded journalist specialising in science and the environment. For years she has reported on how the biosphere is shifting, the destruction of habitats and the extinction of various species, rising sea levels, deforestation and widespread drought. And yet, rather than fully embracing the dire nature of so many scientific prognostications, she has shown determination in mining the facts for glints of light among the gloom, writing about the triumphs of human endeavour, our inventions and discoveries. “We can create new life in a test tube, bring extinct species back from the dead, grow new body parts from cells or build mechanical replacements. We have invented robots to be our slaves, computers to extend our brains, and a new ecosystem of networks with which to communicate… We are supernatural: we can fly without wings and dive without gills, we can survive killer diseases and be resuscitated after death. We are the only species to leave the planet and visit the moon.”
It is in such a spirit – of acknowledging problems and seeking to recognise hopeful moments – that the author ventures out on the explorations that make up this book. The ambition: “to explore the globe at a crucial moment in its living history, at the beginning of this extraordinary new age… As I travelled through our changing planet, I looked at the world we are creating and wondered what sort of Anthropocene we want.” The result is a “story of ingenious inventions, incredible landscapes and about how we have come to our own Gaia for better or for worse.”
Vince is a fine writer, a considerable talent. The sheer scale of this book, which attempts to encompass the entire world and the impact of its dominant species across all of time past, is immense and thoroughly impressive, but at least as impressive is the sense of humanity that she brings to these pages. And the structure of her storytelling technique certainly contributes to the book's success. The author breaks down her observations and ideas into manageable portions across ten chapters, with each one focusing on a geological or environmental specific (under headings such as 'Mountains', 'Rivers', 'Farmlands', 'Rocks', 'Cities' etc.) in order to frame the intent of her bigger picture.
Each chapter opens with a short section of tight, impeccably referenced and statistically-backed scientific writing that puts the targeted subject in context, before shifting tack into social travelogue, with the author taking herself to some of the most remote and deprived corners of the world in order to witness on an intimate level the man-driven changes taking place in real time. These personal interactions, sometimes uncomfortable but rarely less than captivating, help illuminate the numbers, pull her theories to into proper focus, and are the true heart and joy of this book.
Vince kicks off in Nepal ('Atmosphere'), a country where a third of the population live on less than forty cents a day, for an encounter with Mahabir Pun, who, after twenty years in America, has returned on a quest “to transform his tribe's villages through the unlikely medium of Wi-Fi connectivity”. From here, her travels continue, through some of the murkiest and most spectacular corners of China, Africa and South America. Along the way, she accumulates “a series of stories about remarkable people living in extraordinary times.”
In the Maldives ('Ocean'), she meets Mohamed Nasheed, affectionately known as 'Anni', the nation's president known for his staunch position on human rights and a leading political voice on the subject of climate change, a man who once pulled the wild publicity stunt of holding a cabinet meeting underwater in an effort to bring world attention to the subject of rising sea levels.
The African grasslands ('Savannah') finds her walking in the footsteps of all our ancestors with a group of click-speaking Hadzabe tribesmen whose largely Stone Age existence is coming under increasing threat.
Drought-crippled Lake Turkana ('Deserts') is explored in the company of Fabio, a Catholic missionary priest who drives them through warring tribes. It is a place where even the animals, zebras and dik-diks, “travel in convoys to survive banditry.” Water is a two- or three-day walk and the nomadic pastoralists are losing constant ground to ambitious power-generating companies. One such, Desertec, has plans to harvest the gift of the sun (“The Sahara receives as much energy in six hours as the world uses in a year”) and eventually aims to provide 15% of Europe's electricity.
And in the lowlands of Bolivia ('Forests'), Vince learns about humanity's relationship with the world's greatest rainforest from an unlikely Amazonian warrior, a petite sixty-something named Rosa Maria Ruiz, who is risking her life to save it, waging constant battle against the widespread hunting and trafficking of wild animals.
To read 'Adventures in the Anthropocene' is to experience a kind of awakening. Years and even decades of media bombardment has imbued us with an acceptance of the Earth's precarious ecological state, and yet few us ever trouble to peek beneath the veneer of such reportage to the substance of what supports this doomsday talk. Without shirking the negatives, Gaia Vince uncovers enough glimmers of hope that she is able to put forward strategies which might help balance the future scales and allow humanity, and the planet now so firmly under our stewardship, to endure and even to thrive far into the future. In less adroit hands, the plethora of statistics could overwhelm, but the author has achieved a wonderful balance with this book, making it at once thought-provoking and eminently readable. The sheer reality of the numbers, and the depth of their significance, is breathtaking, and yet they capture and focus the imagination on the problems so that the reader cannot help but come away from this book feeling more connected.
