A good read which would benefit from closer fact checking, 5 Aug. 2013
I did enjoy this book and recognise the immense amount of work which obviously went into its production, however I tend to agree with some of the cautions expressed by the previous reviewers. While most errors throughout the book are minor and factual in nature, there are also major conceptual flaws and omissions which mean any claim to expert knowledge should be taken with several pinches of salt. It is difficult to read on after being presented by the claim that "Water, like all matter, can neither be created nor destroyed."(p89). This is wrong on both counts, and wrong in a very fundamental way which I worry exposes some serious flaws in basic knowledge of chemistry and physics. For example, water is effectively 'destroyed' in electrolysis which produces a decomposition of 2H2O --> 2H2+O2, a process which the author claims knowledge of not a few pages prior. As for the production and destruction of matter, the author would do well to swat up on mass-energy equivalence in the laws of conservation of energy.
Having said this, there are simply too many fascinating facts and insights for this to not be read by anyone with an interest in food security and food politics. Well worth the read, but well worth reading with caution.
