There’s no question, none, that so-called lifestyle diseases — diabetes, heart disease, stroke, some cancers — are diseases that are far more prevalent here than anywhere in the rest of the world. And that’s the direct result of eating a Western diet. Our demand for meat, dairy, and refined carbohydrates — the world consumes one billion cans or bottles of Coke a day — our demand for these things, not our need, our want, drives us to consume way more calories than are good for us. And those calories are in foods that cause, not prevent, disease. Now global warming was unforeseen. We didn’t know that pollution did more than cause bad visibility. Maybe a few lung diseases here and there, but, you know, that’s not such a big deal.
