How we live is shaped by how we eat. You can see this in the vastly different approaches to growing, preparing and eating food around the world, such as the hunter-gatherer Hadza in Tanzania whose sustainable lifestyle is under threat in a crowded planet, or Western societies whose food is farmed or bred in vast intensive enterprises. And most of us now rely on a complex global food web of production, distribution, consumption and disposal, which is now contending with unprecedented challenges. The need for a better understanding of how we feed ourselves has never been more urgent. In this wide-ranging and definitive book, philosopher Julian Baggini expertly delves into the best and worst food practises in a huge array of different societies, past and present. His exploration takes him from cutting-edge technologies, such as new farming methods, cultured meat, GM and astronaut food, to the ethics and health of ultra processed food and aquaculture, as he takes a forensic look at the effectiveness of our food governance, the difficulties of food wastage and the effects of commodification. Extracting essential principles to guide how we eat in the future, How the World Eats advocates for a pluralistic, humane, resourceful and equitable global food philosophy, so we can build a food system fit for the twenty-first century and beyond.
