The Population Bomb
The Population Bomb (1968) is a book written by Paul R. Ehrlich. A best-selling work, it predicted disaster for humanity due to overpopulation and the "population explosion". The book predicted that "in the 1970s and 1980s hundreds of millions of people will starve to death", that nothing can be done to avoid mass famine greater than any in the history, and radical action is needed to limit the overpopulation.
Limits to Growth
Limits to Growth is a 1972 book modeling the consequences of a rapidly growing world population and finite resource supplies, commissioned by the Club of Rome. Its authors were Donella H. Meadows, Dennis L. Meadows, Jørgen Randers, and William W. Behrens III. The book used the World3 model to simulate the consequence of interactions between the Earth's and human systems. The book echoes some of the concerns and predictions of Reverend Thomas Robert Malthus in An Essay on the Principle of Population (1798).
