Demography is destiny. It underlies many of the issues that shake the world, from war and economics to immigration. No wonder, then, that fears of overpopulation flared regularly over the last century, a century that saw the world's population quadruple. Even today, baby booms are blamed for genocide and terrorism, and overpopulation is regularly cited as the primary factor driving global warming and other environmental issues.

Yet, surprisingly, it appears that the explosion is past its peak. Around the world, in developing countries as well as in rich ones, today's women are having on average 2.6 children, half the number their mothers had. Within a generation, world fertility will likely follow Europe's to below replacement levels—and by 2040, the world's population will be declining for the first time since the Black Death, almost seven hundred years ago.

In The Coming Population Crash, veteran environmental writer Fred Pearce reveals the dynamics behind this dramatic shift. Charting the demographic path of our species over two hundred years, he begins by chronicling the troubling history of authoritarian efforts to contain the twentieth century's population explosion, as well as the worldwide trend toward the empowerment of women that led to lower birthrates. And then, with vivid reporting from around the globe, he dives into the environmental, social, and economic effects of our surprising demographic future.

Now is probably the last time in history that our world will hold more young people than elders. Most fear that an aging world population will put a serious drain on national resources, as a shrinking working population supports a growing number of retirees. But is this necessarily so? Might an older world population have an upside? Pearce also shows us why our demographic future holds increased migration rates, and reveals the hypocrisy at the heart of anti-immigrant rhetoric in the developed world: the simple fact is that countries with lower birthrates need workers and countries with higher birthrates need work. And he tackles the truism that population density always leads to environmental degradation, taking us from some of the world's most densely packed urban slums to rural Africa to argue that underpopulation can sometimes be the cause of environmental woes, while cities could hold the key to sustainable living.

Pearce's provocative book is essential reading for anyone who wants to know what demographics tell us about our global future, and for all those who believe in learning from the mistakes of the past.

In the popular misconception fostered by blockbuster action movies and best-selling thrillers--not to mention conventional explanations by social scientists--violence is easy under certain conditions, like poverty, racial or ideological hatreds, or family pathologies. Randall Collins challenges this view in Violence, arguing that violent confrontation goes against human physiological hardwiring. It is the exception, not the rule--regardless of the underlying conditions or motivations.

Collins gives a comprehensive explanation of violence and its dynamics, drawing upon video footage, cutting-edge forensics, and ethnography to examine violent situations up close as they actually happen--and his conclusions will surprise you. Violence comes neither easily nor automatically. Antagonists are by nature tense and fearful, and their confrontational anxieties put up a powerful emotional barrier against violence. Collins guides readers into the very real and disturbing worlds of human discord--from domestic abuse and schoolyard bullying to muggings, violent sports, and armed conflicts. He reveals how the fog of war pervades all violent encounters, limiting people mostly to bluster and bluff, and making violence, when it does occur, largely incompetent, often injuring someone other than its intended target. Collins shows how violence can be triggered only when pathways around this emotional barrier are presented. He explains why violence typically comes in the form of atrocities against the weak, ritualized exhibitions before audiences, or clandestine acts of terrorism and murder--and why a small number of individuals are competent at violence.

Violence: A Micro-sociological Theory overturns standard views about the root causes of violence and offers solutions for confronting it in the future.

The most famous scientist of the twentieth century, Albert Einstein was also one of the century's most outspoken political activists. Deeply engaged with the events of his tumultuous times, from the two world wars and the Holocaust, to the atomic bomb and the Cold War, to the effort to establish a Jewish homeland, Einstein was a remarkably prolific political writer, someone who took courageous and often unpopular stands against nationalism, militarism, anti-Semitism, racism, and McCarthyism. In Einstein on Politics, leading Einstein scholars David Rowe and Robert Schulmann gather Einstein's most important public and private political writings and put them into historical context. The book reveals a little-known Einstein--not the ineffectual and naïve idealist of popular imagination, but a principled, shrewd pragmatist whose stands on political issues reflected the depth of his humanity.

Nothing encapsulates Einstein's profound involvement in twentieth-century politics like the atomic bomb. Here we read the former militant pacifist's 1939 letter to President Franklin D. Roosevelt warning that Germany might try to develop an atomic bomb. But the book also documents how Einstein tried to explain this action to Japanese pacifists after the United States used atomic weapons to destroy Hiroshima and Nagasaki, events that spurred Einstein to call for international control of nuclear technology.

A vivid firsthand view of how one of the twentieth century's greatest minds responded to the greatest political challenges of his day, Einstein on Politics will forever change our picture of Einstein's public activism and private motivations.
