Living at High Altitudes 

Life is different at high altitudes. The air is thinner and the sun is brighter. High altitudes can be places of danger and illness, as well as places of incredible natural beauty. People live in large cities and small communities high in the mountains all over the world. This book explores the challenges they have faced over time and how technology has helped them to adapt to this type of environment. Through easy-to-read text and helpful sidebars, readers will also discover how high altitudes affect the body and why some people choose to live there. Compelling photographs and real-life geographical examples will keep readers interested and engaged as they learn about life in this unique, dynamic environment.
