Los números no mienten

Is it dangerous to fly? What is worse for the environment, a car or a mobile? How much do all the cows in the world weigh together and why does this matter? Can you measure happiness? Vaclav Smil's mission is to convince us that facts matter. An environmental scientist, public policy analyst, and tremendously prolific author, he is Bill Gates's benchmark when it comes to understanding the world. In The Numbers Don't Lie, we embark with Smil on a fascinating expedition in search of data that challenges our preconceptions, as he invites us to see with new eyes the impact of the transformations of the modern world on society and the environment. Based on fun examples, amazing statistics and graphs, this book is the perfect combination of ingenuity, history and science that will change the way we see the world. The numbers may not lie, but what truth do they convey?
