IT'S EASY TO DRAW A LINE ON PAPER. BUT WHAT HAPPENS WHEN YOU DEFINE DIVIDING LINES ON THE PLANET? Our world has countless borders and boundaries, from the obvious —like oceans and mountain ranges— to subtle differences in language or climate. Most of us constantly cross invisible lines, yet we rarely recognize them.

In this book, geographer Maxim Samson uses maps and vivid storytelling to present thirty such cases of unseen boundaries, revealing how we confront and experience our world. From the hooligans of Buenos Aires and gangs in Los Angeles to the Malaria Zone in sub-Saharan Africa and air quality in China, the existence of these lines has varying consequences for people, wildlife, and places.

A FASCINATING JOURNEY TO UNDERSTAND THE RELATIONS AND DIVISIONS, DIVERSITY, AND COMPLEXITY OF OUR WORLD.
