How to Feed the World The History and Future of Food

An indispensable analysis of how the world really produces and consumes its food—and a scientist’s exploration of how we can successfully feed a growing population without killing the planet


We have never had to feed as many people as we do today. And yet, we misunderstand the essentials of where our food really comes from, how our dietary requirements shape us, and why this impacts our planet in drastic ways. As a result, in our economic, political, and everyday choices, we take for granted and fail to prioritize the thing that makes all our lives possible: food.

In this ambitious, myth-busting book, Smil investigates many of the burning questions facing the world today: why are some of the world’s biggest food producers also the countries with the most undernourished populations? Why do we waste so much food and how can we solve that? Could the whole planet go vegan and be healthy? Should it? He explores the global history of food production to understand why we farm some animals and not others, why most of the world’s calories come from just a few foodstuffs, and how this might change in the future.

How to Feed the World is the data-based, rigorously researched guide that offers solutions to our broken global food system.
