Be very afraid of what's not on the label
"I thought I had some idea about how supermarkets operate and how our food is produced, but I didn't know the half of it. Read this book (then lend it to everyone you know), ponder its contents for a while and I am sure you will change your shopping habits."
"All the chapters made a big impact but I was particularly moved by the descriptions of the migrant agricultural workers living on rubbish tips in Spain, of coffee farmers who were paid so little for their crop that they couldn't support their families and of the phenomenally destructive (and disgusting) practice of prawn farming in South-East Asia. . . Time and time again what came across is the enormous power of the supermarkets and how in competing with each other to be cheapest they create misery all the way down the food supply chain. Some of the supermarket practices described simply beggar belief."
