Several philosophers have recently argued that policies aimed at reducing human fertility are a practical and morally justifiable way to mitigate the risk of dangerous climate change. There is a powerful objection to such “population engineering” proposals: even if drastic fertility reductions are needed to prevent dangerous climate change, implementing those reductions would wreak havoc on the global economy, which would seriously undermine international antipoverty efforts. In this article, we articulate this economic objection to population engineering and show how it (...) fails. We argue, first, that the economic objection paints an inaccurate picture of the complicated relationship between demographic change and economic growth, and second, that any untoward economic effects of fertility reduction can be mitigated with additional policies. Specifically, we argue that supplementing fertility reduction with policies that facilitate the emigration of younger people from developing nations to developed nations could allow for both global reductions in GHG emissions and continued economic stability. Further, we show that moral arguments against such unprecedented increases in immigration are unsuccessful. We conclude that population engineering is a practical and morally justifiable tool for addressing the twin evils of climate change and global poverty. (shrink)

There are a number of cases where, collectively, groups cause harm, and yet no single individual’s contribution to the collective makes any difference to the amount of harm that is caused. For instance, though human activity is collectively causing climate change, my individual greenhouse gas emissions are neither necessary nor sufficient for any harm that results from climate change. Some (e.g., Sinnott-Armstrong) take this to indicate that there is no individual moral obligation to reduce emissions. There is a collective action (...) problem here, to which I offer a solution. My solution rests on an argument for a (sometimes) bare moral difference between intending harm and foreseeing with near certainty that harm will result as an unintended side-effect of one’s action. I conclude that we have a moral obligation to reduce our individual emissions; and, more broadly, an obligation to not participate in many other harmful group activities (e.g., factory-farming).

A survey of various candidates shows that there is no defensible moral principle that shows that individuals have an obligation to reduce their greenhouse gas emissions.

Consider a duty of beneficence towards a particular individual, S, and call a reason that is grounded in that duty a “beneficence reason towards S.” Call a person who will be brought into existence by an act of procreation the “resultant person.” Is there ever a beneficence reason towards the resultant person for an agent to procreate? In this paper, I argue for such a reason by appealing to two main premises. First, we owe a pro tanto duty of beneficence (...) to future persons; and second, some of us can benefit some of those persons by procreating. In support of the first premise I reject the presentist account of time in favor of the view that future persons are just as real as presently existing persons. I then argue that future persons are like us in all the morally relevant ways, and since we owe duties of beneficence to each other, we also owe duties of beneficence to future persons. In support of the second premise I offer an account of benefiting according to which an individual can be benefited by an action even if it makes her no better off than she would have been, had the action not been performed. This account of benefiting solves what I call the “non-identity benefit problem.” Finally, I argue that having a life worth living is a benefit, and some of us can cause some persons that benefit by causing them to exist.

Esteemed philosopher John Broome avoids the familiar ideological stances on climate change policy and examines the issue through an invigorating new lens. As he considers the moral dimensions of climate change, he reasons clearly through what universal standards of goodness and justice require of us, both as citizens and as governments. His conclusions—some as demanding as they are logical—will challenge and enlighten. Eco-conscious readers may be surprised to hear they have a duty to offset all their carbon emissions, while policy (...) makers will grapple with Broome’s analysis of what if anything is owed to future generations. From the science of greenhouse gases to the intricate logic of cap and trade, Broome reveals how the principles that underlie everyday decision making also provide simple and effective ideas for confronting climate change. Climate Matters is an essential contribution to one of the paramount issues of our time. (shrink)

Climate Change and the Moral Agent examines the moral foundations of climate change and makes a case for collective action on climate change by appealing to moralized collective self-interest, collective ability to aid, and an expanded understanding of collective responsibility for harm.

Standard, familiar models portray harms and benefits as symmetrical. Usually, harm is portrayed as involving a worsening of one's situation, and benefits as involving an improvement. Yet morally, the aversion, prevention, and relief of harms seem, at least presumptively, to matter more than the provision, protection, and maintenance of comparable and often greater benefits. Standard models of harms and benefits have difficulty acknowledging this priority, much less explaining it. They also fail to identify harm accurately and reliably. In this paper, (...) I develop these problems, argue that we should reconsider our commitment to the standard models, and then merely gesture at the direction in which we might locate a superior approach, one that better accounts for the moral significance of harm and its relation to autonomy rights.

Acting Now to End World Poverty Peter Singer. were our own, and we cannot deny that the suffering and death are bad. The second premise is also very difficult to reject, because it leaves us some wiggle room when it comes to situations in.

One of the reasons why most of us feel puzzled about the problem of abortion is that we want, and do not want, to allow to the unborn child the rights that belong to adults and children. When we think of a baby about to be born it seems absurd to think that the next few minutes or even hours could make so radical a difference to its status; yet as we go back in the life of the fetus we (...) are more and more reluctant to say that this is a human being and must be treated as such. No doubt this is the deepest source of our dilemma, but it is not the only one. For we are also confused about the general question of what we may and may not do where the interests of human beings conflict. We have strong intuitions about certain cases; saying, for instance, that it is all right to raise the level of education in our country, though statistics allow us to predict that a rise in the suicide rate will follow, while it is not all right to kill the feeble-minded to aid cancer research. It is not easy, however, to see the principles involved, and one way of throwing light on the abortion issue will be by setting up parallels involving adults or children once born. So we will be able to isolate the “equal rights” issue and should be able to make some advance... (shrink)

“Since the actions I perform as an individual only have an inconsequential effect on the threat of climate change,” a common argument goes, “it cannot be morally wrong for me to take my car to work everyday or refuse to recycle.” This argument has received a lot of scorn from philosophers over the years, but has actually been defended in some recent articles. A more systematic treatment of a central set of related issues shows how maneuvering around these issues is (...) no easy philosophical task. In the end, it appears, the argument from inconsequentialism indeed is correct in typical cases, but there are also important qualificatory considerations. (shrink)

I argue it is inconsistent to believe that overconsumption is wrong or bad yet believe that having children is morally permissible, insofar as they produce comparable environmental impacts, are voluntary choices, and arise from similar desires. This presents a dilemma for "mainstream environmentalists": they do not want to abandon either of those fundamental beliefs, yet must give up one of them. I present an analogical argument supporting that conclusion. After examining four attempts to undermine the analogy, I conclude that none (...) of them successfully locates a significant, relevant difference between procreation and eco-gluttony (roughly, consumption exceeding that of the average American). Thus, in order to be consistent, one must be in favour of both or opposed to both. Mainstream environmentalism, then, is not an option, and should be replaced by radical environmentalism, the view that both overconsumption and (in most cases) having children are morally problematic in an overcrowded world. (shrink)

Several climate ethicists have recently argued that having children is morally equivalent to over-consumption, and contributes greatly to parents’ personal carbon footprints. We show that these claims are mistaken, for two reasons. First, including procreation in parents’ carbon footprints double-counts children’s consumption emissions, once towards their own, and once towards their parents’ footprints. We show that such double-counting defeats the chief purpose of the concept of carbon footprint, namely to measure the sustainability and equitability of one’s activities and choices. Furthermore, (...) we show that proposals to avoid double-counting have other unacceptable implications. Second, we show that the key arguments for a supposed moral equivalence of procreation and consumption overgenerate and lead to unacceptable consequences in many cases, such as for the work of doctors who save lives or enable procreation. Finally, we propose that rather than counting children’s emissions towards their parents’ carbon footprints, we should consider these emissions as part of the parents’ carbon impact, i.e. the difference that their choices make to the overall global carbon emissions. It is from the perspective of impact that we should think about the ethics of procreation in an age of climate change. (shrink)

This book examines the link between population growth and environmental impact and explores the implications of this connection for the ethics of procreation. In light of climate change, species extinctions, and other looming environmental crises, Trevor Hedberg argues that we have a collective moral duty to halt population growth to prevent environmental harms from escalating. This book assesses a variety of policies that could help us meet this moral duty, confronts the conflict between protecting the welfare of future people and (...) upholding procreative freedom, evaluates the ethical dimensions of individual procreative decisions, and sketches the implications of population growth for issues like abortion and immigration. It is not a book of tidy solutions: Hedberg highlights some scenarios where nothing we can do will enable us to avoid treating some people unjustly. In such scenarios, the overall objective is to determine which of our available options will minimize the injustice that occurs. This book will be of great interest to those studying environmental ethics, environmental policy, climate change, sustainability, and population policy. (shrink)

Many environmental philosophers have argued that there is an obligation for individuals to reduce their individual carbon footprints. However, few of them have addressed whether this obligation would entail a corresponding duty to limit one’s family size. In this paper, I examine several reasons that one might view procreative acts as an exception to a more general duty to reduce one’s individual greenhouse gas emissions. I conclude that none of these reasons are convincing. Thus, if there is an obligation to (...) reduce one’s unnecessary greenhouse gas emissions, then people should also limit the size of their families when they have the means to do so. (shrink)

Many philosophers believe that the relationship between a parent and a child is objectively valuable, but few believe that there is any objective value in first creating a child in order to parent her. But if it is indeed true that all of the objective value of procreative-parenting comes from parenting, then it is hard to see how procreative-parenting can overcome two particularly pressing philosophical challenges. A first challenge is to show that it is morally permissible for prospective parents to (...) procreate given that adoption takes us much closer to both environmental and social justice. A second challenge is to show that it is morally permissible for biological parents to parent their biological child given that other prospective parents are willing and able to do a much better job at furthering the child's interests. In this essay, I argue that there is value in procreative-parenting, and that this value is of sufficient magnitude so as to block both the case against procreation and the case in favour of child re-distribution.

In contemporary Western society, people are more often called upon to justify the choice not to have children than they are to supply reasons for having them. In this book, Christine Overall maintains that the burden of proof should be reversed: that the choice to have children calls for more careful justification and reasoning than the choice not to. Arguing that the choice to have children is not just a prudential or pragmatic decision but one with ethical repercussions, Overall offers (...) a wide-ranging exploration of how we might think systematically and deeply about this fundamental aspect of human life. Writing from a feminist perspective, she also acknowledges the inevitably gendered nature of the decision; the choice has different meanings, implications, and risks for women than it has for men. After considering a series of ethical approaches to procreation, and finding them inadequate or incomplete, Overall offers instead a novel argument. Exploring the nature of the biological parent-child relationship -- which is not only genetic but also psychological, physical, intellectual, and moral -- she argues that the formation of that relationship is the best possible reason for choosing to have a child.

It has sometimes been claimed (usually without evidence) that the harm caused by an individual's participation in a greenhouse-gas-intensive economy is negligible. Using data from several contemporary sources, this paper attempts to estimate the harm done by an average American. This estimate is crude, and further refinements are surely needed. But the upshot is that the average American is responsible, through his/her greenhouse gas emissions, for the suffering and/or deaths of one or two future people.

With respect to climate change, what is wanted is an account that morally condemns the production of ‘luxury’ greenhouse gas emissions (e.g., joyriding in an SUV), but not ‘subsistence’ emissions (e.g., cooking meals). Now, our individual greenhouse gas emissions either cause harm, or they do not—and those who condemn the production of luxury emissions generally stake their position on the grounds that they do cause harm. Meanwhile, those seeking to defend the moral permissibility of luxury emissions generally do so by (...) arguing that our individual emissions do not cause harm. Here, I argue that, if our individual emissions do cause harm, then this entails too much. For, it entails not only that our luxury emissions are morally impermissible, but that our subsistence emissions are too. This is an undesirable result. Therefore, I propose that we embrace our other option. Namely, I propose that we accept that our individual emissions do not cause harm; or at least, that they make no perceptible difference with respect to the harms associated with climate change. The result of this admission is not as bad as you might think. For, I argue, even if we are individually causally impotent with respect to the harms of climate change, there remains a plausible route toward the moral condemnation of our individual luxury emissions—contrary to what others have argued. What is more, only by accepting our individual causal impotence can we successfully ground the permissibility of our individual subsistence emissions. (shrink)

It is widely assumed that people have a moral right to procreate. This article explores recent arguments in opposition to procreation in some or all contexts. Some such views are concerned with the risks and harms of life that procreation imposes on non-consenting children. Others articulate concerns for third parties – the environmental damage or opportunity costs that procreation poses to already existing people. The article then surveys arguments that favor procreation despite the risks to the children created and third (...) parties. The best argument for procreation is based on the significant interest people have in forming the parent–child relationship. An important under-discussed middle ground is suggested – one that avoids the criticisms of the anti-natalist while fulfilling the best aims of procreation – viz. adoption. The duty to adopt is summarized and objections to it considered. Thoughtful people who deeply desire to become parents but do not wish to participate in the range of potential procreative harms should consider adoption as a first choice. (shrink)

A compelling argument for the morality of limitations on procreation in lessening the harmful environmental effects of unchecked populationWe live in a world where a burgeoning global population has started to have a major and destructive environmental impact. The results, including climate change and the struggle for limited resources, appear to be inevitable aspects of a difficult future. Mandatory population control might be a possible last resort to combat this problem, but is also a potentially immoral and undesirable violation of (...) human rights. Since so many view procreation as an essential component of the right to personal happiness and autonomy, the dominant view remains that the government does not have the right to impose these restrictions on its own citizens, for the sake of future people who have yet to exist.Sarah Conly is first to make the contentious argument that not only is it wrong to have more than one child in the face of such concerns, we do not even retain the right to do so. In One Child, Conly argues that autonomy and personal rights are not unlimited, especially if one's body may cause harm to anyone, and that the government has a moral obligation to protect both current and future citizens. Conly gives readers a thought-provoking and accessible exposure to the problem of population growth and develops a credible view of what our moral obligations really are, to generations present and future.

The Asymmetry in procreative ethics consists of two claims. The first is that it is morally wrong to bring into existence a child who will have an abjectly miserable life; the second is that it is permissible not to bring into existence a child who will enjoy a very happy life. In this paper, I distinguish between two variations of the Asymmetry. The first is the Abstract Asymmetry, the idealized variation of the Asymmetry that many philosophers have been trying to (...) solve. The second is the Real-World Asymmetry, a non-idealized variation that applies explicitly to cases of ordinary human reproduction. I argue that the Real-World Asymmetry can be defended by properly acknowledging the general wrongness of causing someone else to suffer, the limits of what morality can reasonably demand of us, and the significance of respecting women’s autonomy. I then argue that the Abstract Asymmetry is indefensible. (shrink)

Even though anthropogenic climate change is largely caused by industrialized nations, its burden is distributed unevenly with poor developing countries suffering the most. A common response to livelihood insecurities and destruction is migration. Using Peter Singer's ‘historical principle’, this paper argues that a morally just evaluation requires taking causality between climate change and migration under consideration. The historical principle is employed to emphasize shortcomings in commonly made philosophical arguments to oppose immigration. The article concludes that none of these arguments is (...) able to override the moral responsibility of industrialized countries to compensate for harms that their actions have caused. (shrink)

There is growing acknowledgement of a moral obligation to curb our personal carbon emissions. However, while much has been said regarding certain kinds of carbon- ntensive behaviours, the philosophical literature has – until only very recently – been largely silent regarding one of the worst things that a person can choose to do from a climate perspective: namely, have a child. I contend that procreation is an inessential high-emission activity – one that results in inordinately greater emissions than other activities (...) like joyguzzling or flying. Given this, I argue that if we believe that individuals bear moral responsibility for their personal carbon emissions, then we have strong moral reasons to refrain from choosing to procreate, reasons which – for many – amount to a moral obligation to refrain from choosing to have children. I also consider whether our climate duties might also be discharged by offsetting the climate burden of any children we do choose to have and providing a concrete quantification of what that offsetting might look like.

The distinction between killing and letting die is too simple. A third category must also be recognized. Like killing, preventing a person from being saved is a species of doing harm; like killing, it infringes one of the victim's negative rights. Yet preventing a person from being saved is morally on a par with letting die, which infringes one of the victim's positive rights. It follows that we cannot explain the moral inequivalence of killing and letting die by saying, as (...) so many have, that negative rights are more stringent than positive rights. A more promising strategy is suggested at the end of the article. (shrink)

The main goal of this paper is to explore the forcefulness of the adoption challenge to procreative parenting. After framing the challenge, I consider two of the most developed attempts to respond to it, due to Luara Ferracioli and Elizabeth Brake. I argue that neither strategy is a promising way to vindicate the permissibility of procreative parenting. I then present several reasons to value procreative parenting that are underappreciated in the recent literature. Though these considerations deserve more philosophical attention, I’m (...) agnostic about whether they are strong enough to overcome the adoption challenge. I explain why this agnosticism is reasonable, and the debate about permissibility arguably intractable, in the context of prevailing deontological assumptions structuring discussions of procreation. I conclude by arguing that an independently interesting metaethical thesis, which I call deontic fictionalism, may give us some perspective on this debate and others like it. (shrink)
