Not too long, and the topic provides "plenty" of "food" for discussion. (chuckle) I gave this book a 4 star rating because of just that - it is a current topic that not only gives the reader something to think about, but is likely to provoke opinion and discussion.
Eating locally, is, as some say, "the new organic", appealing to food elitists, and those seeking to reach the epitome of eco-goodness. However, the reality of attempting to grow or source exclusively locally grown food may become far more costly and time-consuming than the average family is willing or able to manage. Nor does it always necessarily make ecological or market sense within the global economy. The most important contribution of this book is to encourage one to think about where our food comes from, to educate ourselves, and to make the best informed decisions we can. By choosing where, how, and what we purchase or consume (or don't purchase or consume!), we shape our world.
