, as well as other major societal upheavals, and advocated immediate action to limit population growth. Fears of a "population explosion" were widespread in the 1950s and 60s, but the book and its charismatic author brought the idea to an even wider audience. The book has been criticized in recent decades for its alarmist tone and inaccurate predictions. The Ehrlichs stand by the basic ideas in the book, stating in 2009 that "perhaps the most serious flaw in The Bomb was that it was much too optimistic about the future" and believe that it achieved their goals because "it alerted people to the importance of environmental issues and brought human numbers into the debate on the human future."

 and a pamphlet issued in 1954 by the Hugh Moore Fund. The Ehrlichs regret the choice of title, which they admit was a perfect choice from a marketing perspective, but think that "it led Paul to be miscategorized as solely focused on human numbers, despite our interest in all the factors affecting the human trajectory."

Early editions of The Population Bomb began with the statement:
Much of the book is spent describing the state of the environment and the food security

 situation, which is described as increasingly dire. Ehrlich argues that as the existing population was not being fed adequately, and as it was growing rapidly it was unreasonable to expect sufficient improvements in food production to feed everyone. He further argued that the growing population placed escalating strains on all aspects of the natural world.

In answer to the question, "what needs to be done?" he wrote, "We must rapidly bring the world population under control, reducing the growth rate to zero or making it negative. Conscious regulation of human numbers must be achieved. Simultaneously we must, at least temporarily, greatly increase our food production." Ehrlich described a number of "ideas on how these goals might be reached." He believed that the United States should take a leading role in population control, both because it was already consuming much more than the rest of the world, and therefore had a moral duty to reduce its impact, and because the US would have to lead international efforts due to its prominence in the world. In order to avoid charges of hypocrisy or racism it would have to take the lead in population reduction efforts. Ehrlich floats the idea of adding "temporary sterilants

" to the water supply or staple foods. However, he rejects the idea as unpractical due to "criminal inadequacy of biomedical research in this area." He suggests a tax scheme in which additional children would add to a family's tax burden at increasing rates for more children, as well as luxury tax

es on childcare goods. He suggests incentives for men who agree to permanent sterilization before they have two children, as well as a variety of other monetary incentives. He proposes a powerful Department of Population and Environment which "should be set up with the power to take whatever steps are necessary to establish a reasonable population size in the United States and to put an end to the steady deterioration of our environment." The department should support research into population control, such as better contraceptives, mass sterilizing agents, and prenatal sex discernment

 should be expanded.

After explaining the domestic policies the US should pursue, he discusses foreign policy. He advocates a system of "triage," such as that suggested by William and Paul Paddock in Famine 1975!. Under this system countries would be divided into categories based on their abilities to feed themselves going forward. Countries with sufficient programmes in place to limit population growth, and the ability to become self sufficient in the future would continue to receive food aid. Countries, for example India, which "were far behind in the population-food game that there is no hope that our food aid will see them through to self-sufficiency" would have their food aid eliminated. Ehrlich argued that this was the only realistic strategy in the long-term. Ehrlich applauds the Paddocks' "courage and foresight" in proposing such a solution. Ehrlich further discusses the need to set up public education programs and agricultural development schemes in developing countries. He argues that the scheme would likely have to be implemented outside the framework of the United Nations

 due to the necessity of being selective regarding the targeted regions and countries, and suggests that within countries certain regions should be prioritized to the extent that cooperative separatist movements should be encouraged if they are an improvement over the existing authority. He mentions his support for government mandated sterilization of Indian males with three or more children.

In the rest of the book Ehrlich discusses things which readers can do to help. This is focused primarily on changing public opinion to create pressure on politicians to enact the policies he suggests, which he believed were not politically possible in 1968. At the end of the book he discusses the possibility that his forecasts may be wrong, a fact which he felt he must acknowledge as a scientist. However, he believes that humanity will only be better off if it follows his prescriptions, so that even if he is incorrect it is the right course of action.

The book sold over two million copies, raised the general awareness of population and environmental issues, and influenced 1960s and 1970s public policy.

’s Road to Survival. Although, they are now much less well known than Population Bomb, they inspired many works such as the original Population Bomb pamphlet by Hugh Everett Moore in 1954 that inspired the name of Ehrlich's book, as well as some of the original societies concerned with population and environmental matters. D.B. Luten has said that although the book is often seen as a seminal work in the field, the Population Bomb is actually best understood as "climaxing and in a sense terminating the debate of the 1950s and 1960s.” Ehrlich has said that he traced his own Malthusian beliefs to a lecture he heard Vogt give when he was attending university in the early 1950s. For Ehrlich, these writers provided “a global framework for things he had observed as a young naturalist."

Restatement of Malthusian theory

The Population Bomb has been characterized by critics as primarily a repetition of the Malthusian catastrophe

 argument that population growth will outpace agricultural growth unless controlled. Ehrlich observed that since about 1930 the population of the world had doubled within a single generation, from 2 billion to nearly 4 billion, and was on track to do so again. He assumed that available resources on the other hand, and in particular food, were nearly at their limits. Some critics compare Ehrlich unfavorably to Malthus, saying that although Thomas Malthus

 did not make a firm prediction of imminent catastrophe, Ehrlich warned of a potential massive disaster within the next decade or two. In addition, critics state that unlike Malthus, Ehrlich did not see any means of avoiding the disaster entirely (although some mitigation was possible), and proposed solutions that were much more radical than those discussed by Malthus, such as starving whole countries that refused to implement population control

 measures.

Ehrlich was certainly not unique in his neo-Malthusian predictions, and there was a wide spread belief in the 1960s and 70s that increasingly catastrophic famines were on their way.

Predictions

The Ehrlichs made a number of specific predictions that did not come to pass, for which they have received criticism. They have acknowledged that some predictions were incorrect. However, they maintain that their general argument remains intact, that their predictions were merely illustrative, that their and others' warnings caused preventive action, or that many of their predictions may yet come true (see Ehrlich's response below). Still other commentators have criticized the Ehrlichs' perceived inability to acknowledge mistakes, evasiveness, and refusal to alter their arguments in the face of contrary evidence.

In The Population Bomb's opening lines the authors state that nothing can prevent famines in which hundreds of millions of people will die during the 1970s (amended to 1970s and 80s in later editions), and that there would be "a substantial increase in the world death rate." Although many lives could be saved through dramatic action, it was already too late to prevent a substantial increase in the global death rate. However, in reality the global death rate has continued to decline substantially since then, from 13/1000 in 1965–74 to 10/1000 from 1985–1990. Meanwhile the population of the world has more than doubled, while calories consumed/person have increased 24%. The UN does not keep official death-by-hunger statistics so it is hard to measure whether the "hundreds of millions of deaths" number is correct. Ehrlich himself suggested in 2009 that between 200-300 million had died of hunger since 1968. However, that is measured over 40 years rather than the ten to twenty foreseen in the book, so it can be seen as significantly fewer than predicted.

, has argued that nations with democracy and a free press have virtually never suffered from extended famines. Nevertheless, in 2010 the UN reported that 925 million of the world's population of nearly seven billion people were in a constant state of hunger. The UN report notes that the percentage of the world's population who qualify as "undernourished" has fallen by more than half, from 33 percent to about 16 percent, since Ehrlich published The Population Bomb.

Ehrlich writes: "I don't see how India

 could possibly feed two hundred million more people by 1980." This view was widely held at the time, as another statement of his, later in the book: "I have yet to meet anyone familiar with the situation who thinks that India will be self-sufficient in food by 1971." In the book's 1971 edition, the latter prediction was removed, as the food situation in India suddenly improved.

As of 2010, India had almost 1.2 billion people, having nearly tripled its population from around 400 million in 1960. India's Total Fertility Rate in 2008 was calculated to be 2.6. While the absolute numbers of malnourished children in India is high, the rates of malnutrition and poverty in India have declined from approximately 90% at the time of India's independence, to less than 40% today. Ehrlich's prediction about famines were found to be false, although food security is an issue in India. However, most epidemiologists, public health physicians and demographers identify corruption as the chief cause of malnutrition, not "overpopulation". As Nobel Prize winning economist Amartya Sen noted, India frequently had famines during British colonial rule. However, when India became a democracy, there have been no recorded famines.

Journalist Dan Gardner has criticized Ehrlich both for his over-confident predictions and his refusal to acknowledge his errors. "In two lengthy interviews, Ehrlich admitted making not a single major error in the popular works he published in the late 1960s and early 1970s … the only flat-out mistake Ehrlich acknowledges is missing the destruction of the rain forests, which happens to be a point that supports and strengthens his world view—and is therefore, in cognitive dissonance

 terms, not a mistake at all. Beyond that, he was by his account, off a little here and there, but only because the information he got from others was wrong. Basically, he was right across the board."

Showmanship

One frequent criticism of The Population Bomb is that it focused on spectacle and exaggeration at the expense of accuracy. Pierre Desrochers and Christine Hoffbauer remark that "at the time of writing The Population Bomb, Paul and Anne Ehrlich should have been more cautious and revised their tone and rhetoric, in light of the undeniable and already apparent errors and shortcomings of Osborn and Vogt’s analyses." Charles Rubin has written that it was precisely because Ehrlich was largely unoriginal and wrote in a clear emotionally gripping style that it became so popular. He quotes a review from Natural History

 helped to propel the success of the book, as well as Ehrlich's celebrity. Desrochers and Hoffbauer go on to conclude that it seems hard to deny that using an alarmist tone and emotional appeal were the main lessons that the present generation of environmentalists learned from Ehrlich's success.

Marxist

On the political left the book received criticism that it was focusing on "the wrong problem", and that the real issue was distribution of resources rather than of overpopulation. Marxists worried that Ehrlich's work could be used to justify genocide and imperial control, as well as oppression of minorities and disadvantaged groups or a even a return to eugenics

 argued that the Ehrlichs 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. He argued that technological, and above all social development would lead to a natural decrease in both population growth and environmental damage.

In answer to the question: "Were your predictions in The Population Bomb right?", Ehrlich responded:
In another retrospective article published in 2009, Ehrlich said, in response to criticism that many of his predictions had not come to pass:
