We must ask ourselves about what is happening in our world today and where is humanity headed. Extinction? Certainly not in a time frame that anyone living today could possibly imagine. But we can look to the long-ago past and the present as our window into the possible far-off future. What can we see through that window? The book paints a landscape of events occurring today that are disturbing. It tells how we have been treating our Mother Earth since we arrived on the scene and how she is responding. We have not been kind siblings.
