Earth Then and Now: Amazing Images of Our Changing World

300 stunning before-and-after photographs that show the staggering transformation of our world.

Earth Then and Now records the dramatic way our planet has changed over the past century. On one page is a specific part of the world as it was 10, 50 or even 100 years ago. On the facing page is the same place as it looks today. Each stark visual comparison tells a compelling story -- a melting glacier, an expanding desert, an encroaching cityscape, a natural disaster.
