Book excerpt: On Social Justice, Climate Change, and Human Destiny is a compilation of the author’s major creative writings on these themes since 1985. Messages within the book warn the human race of its risk of extinction if global plans are not made for survival in this new world age of rapid climate change, devastating climatic events, nuclear threats, and risk of extraterrestrial impact, e.g., by an asteroid. In his novel, The Durabone Prophecies (2011), Harper states, “At all cost, we must assure the perpetuity of our human species and our highly developed technology and scientific knowledge. There is nothing more important for the human race.” Poetry and prose within this book urge human beings around the world to learn how to live in peace and cooperation for the betterment and longevity of humankind.
