Diet for a Hot Planet is subtitled “The Climate Crisis at the End of Your Fork and What You Can Do About It” which should give you a good idea of what this book covers. Anna Lappe (the daughter of Frances Moore Lappe who wrote Diet for a Small Planet back in the 1970s) does a good job of explaining how the food we eat contributes to the climate crisis. There’s a lot to think about and I haven’t processed it all yet, but I know at the very least I will be figuring out how to limit my purchase of items containing palm oil. To establish palm oil plantations (which is apparently in everything from cookies to soap), developers cut down rainforests and drain peatlands (massive amounts of dead and decaying plant matter which are covered by water). When the peatlands are drained this plant matter is exposed to air and begins to oxidize, releasing carbon into the atmosphere. Lappe states that ” [t]hough peatlands cover just 0.2 percent of the earth’s surface their destructions is associated with 8 percent of total global emissions” (p. 30). There’s lots more about this in the book – and about other ways that agriculture and food production impact our planet, so if you are interested (or want it explained better) I recommend that you read it.
(I got Diet for a Hot Planet through LibraryThing’s Early Reviewer’s program for free. Lucky me! I will happily loan it out if other folks would like to read it.)
