In this ambitious, myth-busting book, leading scientist and internationally bestselling author Vaclav 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 is food waste a colossal 1,000kcal per person daily, and how can we solve that? Could we all go vegan and be healthy? Should we? How will we feed the ballooning population without killing the planet? How Food Really Works shows how 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. Ultimately, this data-based, rigorously researched guide explains how we will survive and thrive long into the future.
