Earth Then and Now

I've been looking through Earth Then and Now: Amazing Images of our Changing World from the Waterloo Public Library. This book is a series of before-and-after photographs that show the changes that have taken place in our world.

On one page is a specific part of the world as it was 5, 20, 50 or even 100 years ago. On the facing page is the same place as it looks today. Author Fred Pearce breaks the book into 6 sections:

• Environmental change: Bearing witness to the effects of global warming
• Industrialization: Revealing the hidden costs of "progress"
• Urbanization: Showing the effects of our spreading cities
• Natural disasters: Reminding us of the power of nature
• War: Using comparisons to show the impact of armed conflict
• Travel and tourism: Illustrating the predatory nature of development.

If you want to see environmental changes, it's a book worth looking at.
