I found this book very absorbing and read it from cover to cover in a couple of days.
Tristram Stuart's style of writing is easily read and yet at the same time remains academic and factual. The facts are well cross referenced and where Stuart makes estimations, he clear that these are just such and explains how he has arrived at these.
The amount we as a society waste is certainly staggering. What makes the situation worse is that the fact that it has become harder and harder to use food waste to feed livestock such as pigs and chickens. As a consequence, not only does the calorific value of waste food get lost, we have to grow more food from scratch (such soya by cuttng down rain forest) to feed live stock in order to satisfy the every increasing demand in the world for meat.
Interestingly, this book is on my son's university course's suggested reading list, so it must carry some weight in the academic world too.
