The Population Bomb

Population Bombpopulation
Ehrlich became well known for his controversial 1968 book The Population Bomb, in which he famously stated that "[i]n the 1970s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now." Ehrlich and his wife, Anne H. Ehrlich, collaborated on the book, The Population Bomb, but the publisher insisted that a single author be credited.
The Population Bomb is a best-selling book written by Stanford University Professor Paul R. Ehrlich and his wife, Anne Ehrlich (who was uncredited), in 1968.

Human overpopulation

Among the solutions he suggested in that book was population control, including "various forms of coercion" such as eliminating “tax benefits for having additional children," to be used if voluntary methods were to fail. Ehrlich has been criticized for his opinions; for example, Ronald Bailey termed Ehrlich an "irrepressible doomster". Ehrlich has acknowledged that some of what he predicted has not occurred, but maintains that his predictions about disease and climate change were essentially correct and that human overpopulation is a major problem.
A more controversial definition of overpopulation, as advocated by Paul Ehrlich, is a situation where a population is in the process of depleting non-renewable resources.

Simon–Ehrlich wager

This exchange resulted in the Simon–Ehrlich wager, a bet about the trend of prices for resources during a ten-year period that was made with Simon in 1980.
The Simon–Ehrlich wager was a 1980 scientific wager between business professor Julian L. Simon and biologist Paul Ehrlich, betting on a mutually agreed-upon measure of resource scarcity over the decade leading up to 1990.

Julian Simon

Julian Lincoln SimonJulian L. Simon
Julian Simon, a cornucopian economist, argued that overpopulation is not a problem as such and that humanity will adapt to changing conditions.
He is also known for the famous Simon–Ehrlich wager, a bet he made with ecologist Paul R. Ehrlich.

Sierra Club

The success of the lecture caused further publicity, and the suggestion from David Brower the executive director of the environmentalist Sierra Club, and Ian Ballantine of Ballantine Books to write a book concerning the topic.
In 1969, the Sierra Club published Paul R. Ehrlich's book, The Population Bomb, in which he said that population growth was responsible for environmental decline and advocated coercive measures to reduce it.

Population Connection

Zero Population Growth
Ehrlich was one of the initiators of the group Zero Population Growth (renamed Population Connection) in 1968, along with Richard Bowers and Charles Lee Remington.
The organization was founded in 1968 by Paul R. Ehrlich, Richard Bowers and Charles Remington in the wake of Ehrlich's best-selling book, The Population Bomb.

Barry Commoner

CommonerCommoner and HarrisCommoner, Barry
Barry Commoner has criticized Ehrlich's 1970 statement that "When you reach a point where you realize further efforts will be futile, you may as well look after yourself and your friends and enjoy what little time you have left. That point for me is 1972."
He had a long-running debate with Paul R. Ehrlich, author of The Population Bomb and his followers, arguing that they were too focused on overpopulation as the source of environmental problems, and that their proposed solutions were politically unacceptable because of the coercion that they implied, and because the cost would fall disproportionately on the poor.

Ehrlich earned a bachelor's degree in zoology from the University of Pennsylvania in 1953, an M.A. from the University of Kansas in 1955, and a Ph.D. from the University of Kansas in 1957, supervised by the prominent bee researcher Charles Duncan Michener (the title of his dissertation: "The Morphology, Phylogeny and Higher Classification of the Butterflies (Lepidoptera: Papilionoidea)").
Michener's long career also included the training of more than 80 M.S. and Ph.D. students, among them Jim Baker, Edward M. Barrows, Suzanne W. T. Batra, Michael D.
