The Earth's population has reached over seven billion. Even as war, terror, and environmental catastrophes dominate the headlines, medical science and technology continue to improve our lives. Can we reconcile the two, or is our planet irretrievably lost? Drawing on religious, scientific, and philosophical insights, physicist Michael A. Reimann combines theological and metaphysical views to show mankind's future in "A Letter from God." In an easy-to-read style, Reimann transcribes God's message to humanity and argues that we are at a turning point in our brief but spectacular history on planet Earth. Reimann explores some of the doubts and perplexities humans have experienced throughout history and discusses how scientific discoveries continue to shape human evolution. But at the heart of this discourse is an urgent wake-up call. Overpopulation, pollution, disease, and dependency on fossil fuels continue to send us hurtling toward a crucial breaking point. If we choose to harness the power of technology, abandon organized religion, and practice environmentalism, however, we may yet survive. "A Letter from God" offers an eye-opening, prescient window into humankind's potential destruction-or potential salvation.
