Life and career

Education and academic career

Ehrlich earned a B.A. in zoology in 1953 at the University of Pennsylvania, an M.A. in 1955 at the University of Kansas, and a Ph.D. in 1957 at the University of Kansas, under the prominent bee researcher C.D. Michener. During his studies he participated in surveys of insects on the Bering Sea and in the Canadian Arctic, and then on a National Institutes of Health fellowship, investigated the genetics and behavior of parasitic mites. In 1959 he joined the faculty at Stanford, being promoted to full professor of biology in 1966. He was named to the Bing Professorship in 1977.[2] Zoology (from Greek: ζῴον, zoion, animal; and λόγος, logos, knowledge) is the biological discipline which involves the study of animals. ...

Population growth predictions

Ehrlich wrote an article that appeared in New Scientist in December 1967. In that article, Ehrlich predicted that the world would experience famines sometime between 1970 and 1985 due to population growth outstripping resources. Ehrlich wrote that "the battle to feed all of humanity is over ... In the 1970s and 1980s hundreds of millions of people will starve to death in spite of any crash programs embarked upon now." Ehrlich also stated, "India couldn't possibly feed two hundred million more people by 1980," and "I have yet to meet anyone familiar with the situation who thinks that India will be self-sufficient in food by 1971." These specific predictions did not actually come to pass, and his later book The Population Explosion is much more cautious in its predictions. New Scientist is a weekly international science magazine covering recent developments in science and technology for a general English-speaking audience. ...

The article led to a book (The Population Bomb), the founding of Population Connection|Zero Population Growth, a vigorous policy debate, and both widespread support and criticism of Ehrlich. The Population Bomb (1968) is a book written by Paul R. Ehrlich. ...

Dr. Ehrlich reviewed the predictions in his book The Population Bomb in a 2004 interview and the subsequent criticism that followed due to the specificity of the dates in his predictions.[3] He stated that some of his predictions did not occur, but noted that it was still “horrific” that 600 million people were very hungry and billions under-nourished or malnourished. He stated that his predictions about disease and climate change were correct.[3]

The Population Explosion (1990, co-authored with Anne Ehrlich) was followed two years later by a Centers for Disease Control publication which noted, "During the past three decades, the most common emergencies affecting the health of large populations in developing countries have involved famine and forced migrations."[4] Famine was defined as "a condition of populations in which a substantial increase in deaths is associated with inadequate food consumption".[5] The Centers for Disease Control and Prevention (CDC) in Atlanta is recognized as the lead United States agency for protecting the public health and safety of people by providing credible information to enhance health decisions, and promoting health through strong partnerships with state health departments and other organizations. ...

Other academic authors have echoed Dr. Ehrlich’s concerns about overpopulation. Professor Jared Diamond has argued that population growth and overusing natural resources lead to social collapse.[6] Professor Diamond predicts that these combined factors create an environmental time bomb with an estimated fuse of 50 years, after which he speculates the situation will be resolved one way or another.[6] Jared Mason Diamond (b. ...

Dr. E.O. Wilson, a Harvard biologist and twice a Pulitzer winner, argues that overpopulation and overconsumption could result in the extinction of half of Earth's species sometime in the 21st century.[7] E.O. Wilson with Dynastes hercules E. O. Wilson, or Edward Osborne Wilson, (born June 10, 1929) is an entomologist and biologist known for his work on ecology, evolution, and sociobiology. ...

On the other hand, Professor Ehrlich and his wife Anne have been praised for raising awareness of environmental matters and for bringing to public awareness issues regarding population, resources and environment, as well as making ecology a household word.[8]


Ehrlich has written numerous books on the subjects of ecology, entomology, overpopulation, and related subjects. His best known book is The Population Bomb, published in 1968. The Population Bomb (1968) is a book written by Paul R. Ehrlich. ...
