The absorbing fictional life story of Solomon Isarebe, the visionary who foresaw the route to our climatic redemption through population control. From 9 to 5 explores his predictions and how they compared to the reality of the tumultuous decades from 2050 through to 2150. Anne Wyeth, the fictional author of the book, looks back from 2150 to the changes the world has gone through over the preceding 100 years, describing the impact of a decline in the global population from 9bn to 5bn and the cultural revolutions, economic fortunes, political shifts and global wars that ensued. She compares the reality to the predictions Isarebe made in 2050 in his seminal work, Future Perfect , the best-selling book of the 21st century. Anne Wyeth also paints an evocative portrait of Isarebe, a man whose personal tragedies starkly contrast his unparalleled global achievements. It is a tale of towering ego and genius, love and loss, triumph and disaster, but ultimately, the survival and resilience of both Earth and humanity. Will Isarebe's vision of a future of economic plenty, a cooling climate and a rewilding of planet Earth come true, or will political forces persuade women to have larger families, so threatening Isarebe's roadmap to climatic salvation?
