A scientist speaks about the past, the present, and the future. How does the world really work? The question seems simple, but it is not.

The urbanization of the current population and the advancements of recent decades in agricultural production, energy, and the economy have changed the way we live. Never before have we had such a volume of information at our disposal. Yet most of us, trapped in our specialization and cut off from primary production, are unable to grasp the basic figures and understand the big picture.

In this ambitious and challenging book, a leading scientist of our time analyzes the key factors that determine our survival and prosperity. From energy and food production to raw materials and globalization, the risks we face, the environment, and the future, Vaclav Smil subjects the theories and proposals of today to a thorough verification test based on real, irrefutable data and rational thought.

If we want a better future, we need to change the world. But, to change it, we must first, without prejudice, relying solely on the data, learn how it really works.
