The text's major theme "Changes, Choices, and Constraints" explores: Contemporary "changes "in families and their structure Impacts on the "choices "that are available to family members ""Constraints ""that often limit our choices Through this approach, students are better able to understand what the research and statistics mean "for themselves"! Marriages and Families balances theoretical and empirical discussions with practical examples and applications. It highlights important contemporary changes in society and the family. This text is written from a sociological perspective and incorporates material from other disciplines: history, economics, social work, psychology, law, biology, medicine, family studies, women's studies, and anthropology. "More about the themes: " "Changes"Examines how recent profound structural and attitudinal changes affect family forms, interpersonal relationships, and raising children. It reaches beyond the traditional discussions to explore racial-ethnic families, single-parent families and gay families as well as the recent scholarship by and about men, fathers, and grandfathers. Contemporary American marriages and families vary greatly in structure, dynamics, and cultural heritage. Thus, discussions of gender roles, social class, race, ethnicity, age, and sexual orientation are integrated throughout this book. To further strengthen students understanding of the growing diversity among today's families, the author included a series of boxes that focus on families from many cultures. "Choices"On the individual level, family members have many more choices today than ever before. People feel freer to postpone marriage, to cohabit, or to raise children as single parents. As a result, household forms vary greatly, ranging from commuter marriages to those in which several generations live together under the same roof. "Constraints"Although family members choices are more varied today, we also face greater macro- level constraints. Our options are increasingly limited, for example, by government policies. Economic changes often shape family life and not vice versa. Political and legal institutions also have a major impact on most families in tax laws, welfare reform, and even in defining what a family is. Because laws, public policies, and religious groups affect our everyday lives, the author has framed many discussions of individual choices within the larger picture of the institutional constraints that limit our choices.To learn more about the new edition, click here to visit the showcase site.

    But new technology using concentrated sunlight to provide intense heat energy that can be effectively stored overcomes this problem, providing clean renewable power around the clock. Further, the large amounts of power produced can be used to tackle the issue of feeding the world’s growing population—by enabling energy-intense methods of purifying polluted land for agricultural production.Drawing carbon out of the atmosphere is an essential component in limiting climate change. Flannery explores the potential of kelp, a fast-growing sea algae, to be used on a large scale to convert carbon from the air to a non-gaseous form, reducing levels of atmospheric carbon.With accessible and engaging explanations of the fascinating science behind these technologies, as well as accounts of the systems already in operation around the world, Sunlight and Seaweed is an enlightening and uplifting view of the future.

    But they are under threat as never before, and their problems are spreading across the continent. The Death and Life of the Great Lakes is prize-winning reporter Dan Egan’s compulsively readable portrait of an ecological catastrophe happening right before our eyes, blending the epic story of the lakes with an examination of the perils they face and the ways we can restore and preserve them for generations to come.

    This fascinating and groundbreaking work tells the remarkable story of the relationship between Americans and their trees across the entire span of our nation’s history. Like many of us, historians have long been guilty of taking trees for granted. Yet the history of trees in America is no less remarkable than the history of the United States itself—from the majestic white pines of New England, which were coveted by the British Crown for use as masts in navy warships, to the orange groves of California, which lured settlers west. In fact, without the country’s vast forests and the hundreds of tree species they contained, there would have been no ships, docks, railroads, stockyards, wagons, barrels, furniture, newspapers, rifles, or firewood. No shingled villages or whaling vessels in New England. No New York City, Miami, or Chicago. No Johnny Appleseed, Paul Bunyan, or Daniel Boone. No Allied planes in World War I, and no suburban sprawl in the middle of the twentieth century. America—if indeed it existed—would be a very different place without its millions of acres of trees. As Eric Rutkow’s brilliant, epic account shows, trees were essential to the early years of the republic and indivisible from the country’s rise as both an empire and a civilization. Among American Canopy’s many fascinating stories: the Liberty Trees, where colonists gathered to plot rebellion against the British; Henry David Thoreau’s famous retreat into the woods; the creation of New York City’s Central Park; the great fire of 1871 that killed a thousand people in the lumber town of Peshtigo, Wisconsin; the fevered attempts to save the American chestnut and the American elm from extinction; and the controversy over spotted owls and the old-growth forests they inhabited. Rutkow also explains how trees were of deep interest to such figures as George Washington, Thomas Jefferson, Benjamin Franklin, Teddy Roosevelt, and FDR, who oversaw the planting of more than three billion trees nationally in his time as president. As symbols of liberty, community, and civilization, trees are perhaps the loudest silent figures in our country’s history. America started as a nation of people frightened of the deep, seemingly infinite woods; we then grew to rely on our forests for progress and profit; by the end of the twentieth century we came to understand that the globe’s climate is dependent on the preservation of trees. Today, few people think about where timber comes from, but most of us share a sense that to destroy trees is to destroy part of ourselves and endanger the future. Never before has anyone treated our country’s trees and forests as the subject of a broad historical study, and the result is an accessible, informative, and thoroughly entertaining read. Audacious in its four-hundred-year scope, authoritative in its detail, and elegant in its execution, American Canopy is perfect for history buffs and nature lovers alike and announces Eric Rutkow as a major new author of popular history.

    As she grows into adulthood, only a few of her eggs mature, are released into the oviduct, and are fertilized by sperm stored from copulation that took place days or weeks earlier. Within a matter of hours, the fragile yolk is surrounded by albumen and the whole is gradually encased within a turquoise jewel of a shell. Soon afterward the fully formed egg is expelled onto a bare rocky ledge, where it will be incubated for four weeks before another chick emerges and the life cycle begins again. The Most Perfect Thing is about how eggs in general are made, fertilized, developed, and hatched. The eggs of most birds spend just 24 hours in the oviduct; however, that journey takes 48 hours in cuckoos, which surreptitiously lay their eggs in the nests of other birds. From the earliest times, the study of birds' ovaries and ova (eggs) played a vital role in the quest to unravel the mysteries of fertilization and embryo development in humans. Birkhead uses birds' eggs as wondrous portals into natural history, enlivened by the stories of naturalists and scientists, including Birkhead and his students, whose discoveries have advanced current scientific knowledge of reproduction.

    With an entire chapter unpacking the climate change denier’s point of view, he advocates for expanding our exclusive focus on carbon emissions to see the broader picture beyond our short-sighted and incomplete approach. The rivers, forests, and creatures of the natural and material world are sacred and valuable in their own right, not simply for carbon credits or preventing the extinction of one species versus another. After all, when you ask someone why they first became an environmentalist, they’re likely to point to the river they played in, the ocean they visited, the wild animals they observed, or the trees they climbed when they were a kid. This refocusing away from impending catastrophe and our inevitable doom cultivates meaningful emotional and psychological connections and provides real, actionable steps to caring for the earth. Freeing ourselves from a war mentality and seeing the bigger picture of how everything from prison reform to saving the whales can contribute to our planetary ecological health, we resist reflexive postures of solution and blame and reach toward the deep place where commitment lives.

    What are the major environmental policy changes under the George W. Bush administration, and how do they compare with policies of previous administrations? What are the merits - and limits - of recent market approaches to environmental regulation and management? How can students best understand the concept of acceptable risk and other scientifically-based decision making tools with regard to the regulation of toxic substances? Rosenbaum's classic, comprehensive text - now in a totally revised sixth edition - offers definitive coverage of environmental politics and policy, lively case material, and a balanced assessment of current environmental issues. actors, institutions, and processes involved in environmental policymaking, giving students a solid foundation for understanding our most pressing environmental concerns.

    Only a few species of wild animals can survive its harsh climate. In this modern classic, Barry Lopez explores the many-faceted wonders of the Far North: its strangely stunted forest, its mesmerizing aurora borealis, its frozen seas. Musk oxen, polar bears, narwhal, and other exotic beasts of the region come alive through Lopez’s passionate and nuanced observations. And, as he examines the history and culture of the indigenous people, along with parallel narratives of intrepid, often underprepared and subsequently doomed polar explorers, Lopez drives to the heart of why the austere and formidable Arctic is also a constant source of breathtaking beauty, beguilement, and wonder.Written in prose as memorably pure as the land it describes, Arctic Dreams is a timeless mediation on the ability of the landscape to shape our dreams and to haunt our imaginations.

    Gathering Moss is a beautifully written mix of science and personal reflection that invites readers to explore and learn from the elegantly simple lives of mosses. Robin Wall Kimmerer's book is not an identification guide, nor is it a scientific treatise. Rather, it is a series of linked personal essays that will lead general readers and scientists alike to an understanding of how mosses live and how their lives are intertwined with the lives of countless other beings, from salmon and hummingbirds to redwoods and rednecks. Kimmerer clearly and artfully explains the biology of mosses, while at the same time reflecting on what these fascinating organisms have to teach us.Drawing on her diverse experiences as a scientist, mother, teacher, and writer of Native American heritage, Kimmerer explains the stories of mosses in scientific terms as well as in the framework of indigenous ways of knowing. In her book, the natural history and cultural relationships of mosses become a powerful metaphor for ways of living in the world.Gathering Moss will appeal to a wide range of readers, from bryologists to those interested in natural history and the environment, Native Americans, and contemporary nature and science writing.

    The earthworm may be small, spineless, and blind, but its impact on the ecosystem is profound. It ploughs the soil, fights plant diseases, cleans up pollution, and turns ordinary dirt into fertile land. Who knew? In her witty, offbeat style, Stewart shows that much depends on the actions of the lowly worm. Charles Darwin devoted his last years to the meticulous study of these creatures, praising their remarkable abilities. With the august scientist as her inspiration, Stewart investigates the worm's subterranean realm, talks to oligochaetologists—the unsung heroes of earthworm science—who have devoted their lives to unearthing the complex life beneath our feet, and observes the thousands of worms in her own garden. From the legendary giant Australian worm that stretches to ten feet in length to the modest nightcrawler that wormed its way into the heart of Darwin's last book to the energetic red wigglers in Stewart's compost bin, The Earth Moved gives worms their due and exposes their hidden and extraordinary universe. This book is for all of us who appreciate Mother Nature's creatures, no matter how humble.

    It is also a place of extraordinary beauty. Evolutionary biologist Alex Dehgan arrived in the country in 2006 to build the Wildlife Conservation Society's Afghanistan Program, and preserve and protect Afghanistan's unique and extraordinary environment, which had been decimated after decades of war.Conservation, it turned out, provided a common bond between Alex's team and the people of Afghanistan. His international team worked unarmed in some of the most dangerous places in the country-places so remote that winding roads would abruptly disappear, and travel was on foot, yak, or mule. In The Snow Leopard Project, Dehgan takes readers along with him on his adventure as his team helps create the country's first national park, completes the some of the first extensive wildlife surveys in thirty years, and works to stop the poaching of the country's iconic endangered animals, including the elusive snow leopard. In doing so, they help restore a part of Afghan identity that is ineffably tied to the land itself.

    Both the book and film were inspired by a series of multimedia presentations on global warming that Gore created and delivers to groups around the world. With this book, Gore, who is one of our environmental heroes—and a leading expert—brings together leading-edge research from top scientists around the world; photographs, charts, and other illustrations; and personal anecdotes and observations to document the fast pace and wide scope of global warming. He presents, with alarming clarity and conclusiveness—and with humor, too—that the fact of global warming is not in question and that its consequences for the world we live in will be disastrous if left unchecked. This riveting new book—written in an accessible, entertaining style—will open the eyes of even the most skeptical.
