This story was originally published by Grist and is reproduced here as part of the Climate Desk collaboration. Early into his new book, The Blue Plate: A Food Lover’s Guide to Climate Chaos, ecologist Mark Easter poses a playful, but loaded, question: “How could a morning piece of toast or a plate of dinner pasta be such a world-altering culprit?” This, like many ideas Easter digs into in his illuminating debut, is a glimpse at how the author goes about breaking down the climate toll of the US agricultural system: One dish at a time. Seafood, salad, bread, chicken, steak, potatoes, and pie are just some of the quintessentially “American” kitchen table staples Easter structures the book around as he tries to help readers understand how greenhouse gases move into and out of soils and plants on land across the country.
