Below is an editorial that was published in the journal Conservation Biology. I had had a dream of publishing something about human population’s effect on the natural world in Conservation Biology for years. Two articles were rejected and I was dejected. Then the journal’s new editor, Erica Fleishman, gave me the opportunity I was hoping for. She was wonderful to work with, helping to shape the piece and adding her own spin. I had to hold it in quarantine for a year after it was published.

If you get a chance to read the 25th anniversary issue of Conservation Biology (Volume 26, Number 6,December 2011), I strongly recommend the articles in the two Special Sections. They are available without charge at:Â http://onlinelibrary.wiley.com/doi/10.1111/cobi.2011.25.issue-6/issuetoc

Editorial

Birds and Bees for Biologists

My background is different from most readers of Conservation Biology. I chose a career in medicine and specialized in obstetrics and gynecology because of my concern about the human population. Initially I was worried about how the increase of human population would adversely affect my own species. In the last two decades, I have realized how profoundly we have affected the natural world and how we have caused the extinction of so many other species. To me it is unthinkable not to take action to preserve Creation and to prevent the loss of biological diversity.

It is frustrating for conservation professionals to be aware of the root causes of loss of biological diversity but not know what actions to take as individuals to lessen the effects humans have on biological diversity (Meffe et al. 1993; Meffe 1994). We know the human ecological footprint on the planet is now about 40% greater that what Earth can support sustainably (Wackernagel 2009). Our community can, however, slow the loss of biological diversity if we make it a priority to discuss family planning, consumption, and consumerism. Minimizing loss of biological diversity will require the efforts of many thousands of people in scores of disciplines and that people change their behavior. The approach to take to change human behavior will need to be multidisciplinary (Ehrlich 2010).

Almost 40 years ago Ehrlich and Holdren (1971) proposed a formula to estimate the effect of humans on the natural world: I=PÃ—AÃ—T,where I is impact, P is population, A is affluence, and T is technology. Of the three contributing factors, human population and affluence (or consumption) affect impact most strongly.

Ironically, these same two factors also endanger human society. Our extravagant use of fossil fuels is changing the climate of our planet. We know some of the effects climate change will have on species that are less mobile and flexible than humans, but we can only speculate on how our own species will be affected. For example, inundation of coastal land, crop failures, spread of disease, and increased armed conflict will likely accompany our new climate. It is predicted that people living in low-income countries and low-income people in high-income countries will suffer more from climate change than high-income people.

Many economic and political systems, with their stress on economic growth and affluence, are partly responsible for the current situation. Capitalism does not reward simple living. Many countries have pronatalist benefits or have social and economic systems that favor large families. For instance, in the United States the federal income tax code allows a deduction for every child in a family. Many societies value male children more than females; thus, women continue to bear children until a son is born.

In many societies it is taboo to talk about personal wealth or reproductive choices. Can you imagine meeting someone and asking how much money she has in the bank, or asking an acquaintance if his wife is taking birth control pills? It is possible, however, to avoid the taboo and still address the important issues of consumption and reproduction by being sensitive and choosing the proper setting. For instance, it is acceptable to discuss money in a financial institution and reproduction in a physicianâ€™s office.

In certain situations it is also acceptable for conservation professionals to discuss affluence and the choice of family size. Many of us are teachers or have contact with young people in other capacities. Conservation professionals can help young people make informed decisions about lifestyle and family size. Conservation professionals are qualified to teach about the effects of human population growth and high levels of consumption on the natural world and thus to discuss the advantages of a small family size and a simple lifestyle.

Despite strong social pressure, some people choose to consume relatively few resources. In many cases they trade higher incomes (and thus increased consumption) for simpler lifestyles. There is a long history of people voluntarily choosing a life of simplicity. The concept of a simple life has been overshadowed by the rise of com- mercialism, and the concept has only recently been redis- covered. Studies that compare the happiness of people in different countries suggest that income does not predict happiness. Although people in the United States have the highest income, the largest ecological footprint, and consume the most resources, they are not the happiest. A worldwide Gallup survey found that people in several countries with lower incomes than the United States areÂ happier than people in the United States (English 2010). People in Costa Rica, for instance, are happier and consume much less than people in the United States.

People who have chosen a simpler lifestyle say they have more time to enjoy the pleasures of life. This is a benefit in addition to reducing oneâ€™s impact on the envi- ronment. More information on simple lifestyle is available on the Internet (search terms simple living and voluntary simplicity).

Already people are choosing to have smaller families than just 60 years ago. In 1950 the average number of children that women worldwide bore in their lifetime was 6; now the average is just 2.5. Many factors influence the number of children a woman bears during her lifetime. They include societal and religious norms, access to modern contraception, educational level, and whether she can expect her children to live to adulthood.

In many parts of the world people do not have access to modern family planning. Sometimes access is limited by lack of healthcare or barriers erected by medical systems, and in other cases poverty is an obstacle. Often people do not know enough about the advantages of contraception or there are social barriers to its use. Worldwide it is estimated that over 200 million couples want modern contraception but do not have access to it (Singh et al. 2009).

Social marketing can be an important means of inform- ing people about family size and contraception. Many people make erroneous assumptions about the effects of family planning methods on their health or are otherwise misinformed. Some have little knowledge of contraception and how to access it. Others believe they do not have a choice in the size of their familiesâ€”that family size is determined by society or God.

Radio and television programs, such as serials (soap operas), have been very effective in empowering women, informing people about the advantages (and trade-offs) of small families, and teaching strategies to avoid HIV. The Population Media Center of Shelburne, Vermont (U.S.A.), has successfully educated people on these topics through such programming in over 18 countries. The Center for Biological Diversity of Tucson, Arizona (U.S.A.), has taken a novel approach to informing the public about the relation between human population growth and loss of biological diversity. They have distributed over one-third of a million Endangered Species Condoms. On each package is printed information about the interaction of human population growth and extinction of species.

All family planning must be voluntary for ethical reasons and because coercion may be counterproductive. For instance, in India during the mid-1970s people were coerced by the government through monetary payments into being surgically sterilized. People rebelled against these programs with the result that acceptance of family planning was set back.

For the social scientists among us there are many opportunities. In addition to designing programs to help minimize our footprints, social scientists can study the effectiveness of these efforts. Some conservation organizations working in and near locations with relatively high species richness have already incorporated family planning into the human services they offer as part of their conservation work (Cincotta & Engelman 2000). Although it seems intuitive that decreasing human population growth rates should decrease the loss of biological diversity, so far the results of few stud- ies support this expected interaction (e.g., Jha & Bawa 2006).

Conservation professionals have sought to save biological diversity by preserving speciesâ€™ habitats, controlling non-native species, preventing unsustainable harvest, and cleaning up pollution. I suggest another powerful means to protect our progenyâ€™s legacy. We can inform future generations about the effects of simple living and small familiesâ€”for their own benefit, but especially for the benefit of the natural world.

How will this Halloween be different from any other Halloween? A singular event will happen this October 31^st.

That is the day demographers predict a very special baby will be bornâ€”the Earthâ€™s 7 billionth citizen! She will probably arrive in a developing country, because that is where most of the planetâ€™s babies are born.

What else can we say about this unique, but unidentifiable person? Letâ€™s assume she is a girl. However, in the worldâ€™s two largest countries, China and India, girls are selected against because people value boys more than girls. Early in pregnancy some women pay for illegal ultrasounds done to determine if they are carrying a boy or a girl. If a girl, she is likely to be aborted.

And, as incredible as it may seem, femicide (selective killing of baby girls shortly after birth) is still practiced.

If the seven billionth baby is a girl born in a poor country, she will probably go to school for only a few years. Even if she finishes the elementary grades, it is unlikely that she will graduate from high school. Her lack of education is partially due to difficulty paying tuition and for the books, shoes and school uniform she would need. She will also be needed at home. Her chores will include helping her mother cook, caring for younger kids, and gathering firewood and water. It is common for women and girls to walk miles every day just to fetch water.

She may be held down and have her genitals mutilated if she lives in certain areas of Africa or the Middle East. This girl also may be promised to her future husband as a child, and be forced to marry even before she reaches puberty. It is likely that she will become pregnant as a teen, knowing little of family planning. If she is lucky, she will have a healthy baby, but too many of these young brides grow a baby larger than their bones can accommodate, with disastrous results.

She will probably stay at home when she goes into labor. If she is lucky her attendant will be a trained midwife. Too often traditional birth attendants have no formal training and rely on old wivesâ€™ tales to welcome new life. Women in labor in poor countries die at alarming rates from hemorrhage, infection and toxemia.

What can this person look forward to? I expect that the world she will join will be very different from the world that we have enjoyed. When she is a teen petroleum will be less plentiful and very pricey. As a result we in the USA will go back to many aspects of the lifestyle of our great-grandparents. We will travel less, since fuel will be very expensive. Â We will live close to work to save fuel. And our homes will be smaller to save on heating and cooling.

Food will become a much larger portion of everyoneâ€™s budget. Remember the reason that food is relatively inexpensive is that much of the work to raise it depends on petroleum, and petroleum is used to make the chemicals that boost production. The worldâ€™s population has grown at a record rate in the last century largely due to the availability of inexpensive food.

Can we look 20 years into this special young ladyâ€™s future? She may be the mother of young children, and perhaps already had a child die from lack of safe water and adequate food. Her responsibilities will include cooking and caring for her family and helping her husband in the fields. If she is lucky, she may have her own small microenterprise, selling food or wares.

Past traditions will not have prepared her well for the future, since the world is changing very rapidly. In 2031 it would take two planets Earth to support our burgeoning population sustainably, unless we make enormous changes. We can alter our lifestyles to consume less; indeed, we may be forced to make substantial change. Less travel, more efficient use of energy resources and more renewable energy will become the norm.

Enabling smaller family size will be the key to continued existence. Family planning will help both survival of humans and also survival of other members of the web of life upon which we are so dependent.

This Halloween you can look forward to the usual spooks and demons at your doorstep. In addition, however, glimpse into the future and you will see the specter of human overpopulation.
