This is an update of E.F. Schumacher's famous 1973 book "Small is Beautiful." While I don't think you need to have read that book in order to get a lot of good from this work, it's helpful to read it, because it was a seminal work in its time and its great to see the resonance of those ideas a generation or two removed.
Pearce makes a compelling case that we are truly screwing things up when it comes to economics, technology, our food supply, our environment, and how we treat our fellow humans, especially at a time when we have so much potential to get these things right.
Important quotes from the book:
"The accelerating depletion of the earth's finite resources to meet ever-expanding demands for energy and consumer goods has no foreseeable end." p. 7
"They have forgotten that it is not the quantity of things possessed by the quality of life lived that matters." p. 25
"...the developed world should be called the overdeveloped world." p. 36
"Trade, which is in its nature a secondary or dependent thing, has been treated as a primary and independent thing; as an absolute. The moderns, mad upon mere multiplication, have even made a plural out of what is essentially singular, in the sense of single. They have taken what all ancient philosophers called the Good, and translated it as Goods." p. 42, quoting G.K. Chesterton
"The stark reality is that the average American uses 33 times as much energy as the average Indian and almost 150 times as much as the average person in Bangladesh." p. 45
"Global free trade has become an unquestionable moral dogma enshrined at the heart of modern economic theory...it is possible, even likely, that the globalization of trade will destabilize the industrialized world while at the same time exacerbating the problems facing the developing world." p. 51
"The very suggestion that there can be infinite growth in a finite space with finite resources is an obvious absurdity. Yet there can be no reduction in growth and no sustainable future for as as long as the distinction between need and desire is deliberately disregarded for the sake of corporate gain." p. 70
"...a growing awareness of the fact that one cannot use with impunity the different categories of beings, whether living or inanimate - animals, plants, the natural elements - simply as one wishes, according to one's own economic needs." p. 81
"...the main danger to the soil, and therewith not only to agriculture but to civilization as a whole, stems from the townsman's determination to apply to agriculture the principles of industry." p. 155, quoting Schumacher
"Techno-man, devoid of any metaphysical understanding, knows how to do things without knowing why or whether they should be done. We do them because we can, not because we should." p. 279
"There can be no solutions to the world's problems until their causes are properly understood." p. 288
It's not a long read, and well worth your time.
