Climate change is the single biggest threat to human survival - and we are dealing with it all wrong. We take shorter showers to save water - because we don't know that producing one pound of meat requires the equivalent of six months' showers in water waste. We buy hybrid cars - because we don't know that just one day a week without meat consumption is equivalent to taking every car in America off the road. The link between meat-eating and the climate crisis isn't talked about - because our leaders think we're not ready to make small personal sacrifices to save our way of life. But these sacrifices need to be made - and they're so much easier than you think. You don't have to go cold turkey. Cutting out meat for just part of the day is enough to change the world. With his distinctive wit, insight and humanity, Jonathan Safran Foer presents this essential debate as no one else could, bringing it to vivid and urgent life, and offering us all a much-needed way out.
