The Big Ratchet: How Humanity Thrives in the Face of Natural Crisis, by Ruth DeFries
€8.00

Quay Books
How an ordinary mammal manipulated nature to become technologically sophisticated city-dwellers - and why our history points to an optimistic future in the face of environmental crisis
Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day.
This is such an astonishing thing in the history of life as to verge on the miraculous. The Big Ratchet is the story of how it happened, of the ratchets - the technologies and innovations, big and small - that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket.
The Big Ratchet itself came in the twentieth century, when a range of technologies - from fossil fuels to scientific plant breeding to nitrogen fertilizers - combined to nearly quadruple our population in a century, and to grow our food supply even faster.
To some, these technologies are a sign of our greatness; to others, of our hubris. Ruth DeFries argues that the debate is the wrong one to have. Limits do exist, but every limit that has confronted us, we have surpassed. That cycle of crisis and growth is the story of our history; indeed, it is the essence of The Big Ratchet. Understanding it will reveal not just how we reached this point in our history, but how we might survive it.
“[The Big Ratchet] is a fast-moving and information-packed history of human appetites.... DeFries does environmentalism a favor by presenting this history as a dialectic that never ends.” - Orion
“[A]n interesting and timely thesis.... This is an environmental history, chockablock with examples from the past that might guide us in the future.” - Toronto Star
