The State of Humanity, the product of over 60 authorities, updates and vastly expands the 1984 book The Resourceful Earth, edited by Simon and the late Herman Kahn. That book was intended to refute the influential 1980 Global Report to the President, which warned that “the world in 2000 will be more crowded, more polluted, less stable ecologically, and more vulnerable to disruption than the world we live in now.” In The Resourceful Earth, economists and scientists argued that the trends of the material conditions of the human race were all positive. As Simon writes in his introduction to The State of Humanity, “The years have been kind to our  forecasts–or more importantly, the years have been good for humanity.”
The new volume assembles the work of an impressive array of experts not only in fields related to material resources but also in such areas as life expectancy, childhood mortality, health and disease, murder and suicide, and leisure time. The authors conclude that, despite the forecasters of doom, things continue to improve worldwide year by year. Other trends that persist on favorable paths include energy prices, oil supplies, nonrenewable resources, global forests, agricultural productivity, fish, farmland quality, and water and air quality. Fears about nuclear power, acid rain, global warming, stratospheric ozone, pesticides, and cancer are allayed. The final section of the book looks at public opinion on issues such as population growth and the environment.
“Every forecast of the doomsayers has turned out to be wholly wrong,” Simon writes in his introduction. “There is no convincing economic reason why these trends toward a better life should not continue indefinitely.”
