The Last Hours of Ancient Sunlight by Thom Hartmann (1998, Paperback)

Thom Hartmann takes you through evolution starting tens-of-thousands of years ago to show how civilization of mankind has exploited and doomed the very planet it dwells upon.

"The Last Hours of Ancient Sunlight" talks about man's use and abuse of planet's resources and how our life-supply of "ancient sunlight" is running out quickly. Unless we can learn to change our ways of frittering away our planetary assets, we could find ourselves in the Dark Ages sometime in the future.

The best part about the book is that Hartmann actually offers potential solutions and methods to change our destructive behaviours and actions. An excellent read for anyone who is concerned about global decimation.
