 The climatarian diet is supposed to carry dual benefits, not only for the consumer, who will enjoy healthier diet, but also for the planet as a whole, by reducing the climate impact of food production.Proponents of climatarianism claim that the diet is based on clear scientific data, as it seeks to reduce the consumption of those foods that are identified as the largest emitters of greenhouse gases responsible for climate change.One of the main ways in which climatarians strive to make their food consumption less environmentally harmful is by avoiding eating beef and lamb.
