Description:
Throughout the developed world, debate is raging over the use of genetically modified (GM) food and food additives. This debate, Canadian agricultural scientist McHughen holds, is not well-informed. "Everyone, it seems, is concerned about GM food," he writes, "but most admit they don't really know much about it." This is especially true in North America, where millions of acres of GM crops are now produced and GM foods are widely consumed, although it is no less true of Europe, where production and consumption alike are comparatively low. McHughen recognizes that some of these concerns are well-founded, even if the discussion is not, and his book is a thoughtful examination of some of the basic scientific issues involved in whether genetic modification may turn out to yield harmful (or, conversely, beneficial) results. These issues, he goes on to say, are of two broad kinds: first, whether a GM product is safe for the environment, and whether it can be prevented from "escaping" into nature; and second, whether a GM product is safe for the animal or human consumer. His answers may not always please activists on either side of the issue, for he suggests that while in the main GM production is likely to be a good thing, particularly in areas of the world where agricultural yields are low, there may yet be unanticipated risks involved--especially because "nature has no plan for agricultural systems based on high chemical inputs and low biodiversity." --Gregory McNamee
