"Life on the Brink" aspires to reignite a robust discussion of population issues among environmentalists, environmental studies scholars, policymakers, and the general public. Some of the leading voices in the American environmental movement restate the case that population growth is a major force behind many of our most serious ecological problems, including global climate change, habitat loss and species extinctions, air and water pollution, and food and water scarcity. As we surpass seven billion world inhabitants, contributors argue that ending population growth worldwide and in the United States is a moral imperative that deserves renewed commitment.
Hailing from a range of disciplines and offering varied perspectives, these essays hold in common a commitment to sharing resources with other species and a willingness to consider what will be necessary to do so. In defense of nature and of a vibrant human future, contributors confront hard issues regarding contraception, abortion, immigration, and limits to growth that many environmentalists have become too timid or politically correct to address in recent years.
Ending population growth will not happen easily. Creating genuinely sustainable societies requires major change to economic systems and ethical values coupled with clear thinking and hard work. "Life on the Brink" is an invitation to join the discussion about the great work of building a better future.

Protected natural areas have historically been the primary tool of conservationists to conserve land and wildlife. These parks and reserves are set apart to forever remain in contrast to those places where human activities, technologies, and developments prevail. But even as the biodiversity crisis accelerates, a growing number of voices are suggesting that protected areas are passe. Conservation, they argue, should instead focus on lands managed for human use--working landscapes--and abandon the goal of preventing human-caused extinctions in favor of maintaining ecosystem services to support people. If such arguments take hold, we risk losing support for the unique qualities and values of wild, undeveloped nature.
"Protecting the Wild" offers a spirited argument for the robust protection of the natural world. In it, experts from five continents reaffirm that parks, wilderness areas, and other reserves are an indispensable--albeit insufficient--means to sustain species, subspecies, key habitats, ecological processes, and evolutionary potential. Using case studies from around the globe, they present evidence that terrestrial and marine protected areas are crucial for biodiversity and human well-being alike, vital to countering anthropogenic extinctions and climate change.
A companion volume to "Keeping the Wild: Against the Domestication of Earth," "Protecting the Wild" provides a necessary addition to the conversation about the future of conservation in the so-called Anthropocene, one that will be useful for academics, policymakers, and conservation practitioners at all levels, from local land trusts to international NGOs.

Is it time to embrace the so-called "Anthropocene"--the age of human dominion--and to abandon tried-and-true conservation tools such as parks and wilderness areas? Is the future of Earth to be fully domesticated, an engineered global garden managed by technocrats to serve humanity? The schism between advocates of rewilding and those who accept and even celebrate a "post-wild" world is arguably the hottest intellectual battle in contemporary conservation.In Keeping the Wild, a group of prominent scientists, writers, and conservation activists responds to the Anthropocene-boosters who claim that wild nature is no more (or in any case not much worth caring about), that human-caused extinction is acceptable, and that "novel ecosystems" are an adequate replacement for natural landscapes. With rhetorical fists swinging, the book's contributors argue that these "new environmentalists" embody the hubris of the managerial mindset and offer a conservation strategy that will fail to protect life in all its buzzing, blossoming diversity. With essays from Eileen Crist, David Ehrenfeld, Dave Foreman, Lisi Krall, Harvey Locke, Curt Meine, Kathleen Dean Moore, Michael Soule, Terry Tempest Williams and other leading thinkers, Keeping the Wild provides an introduction to this important debate, a critique of the Anthropocene boosters' attack on traditional conservation, and unapologetic advocacy for wild nature.

Essays link Gaian science to such global environmental quandaries as climate change and biodiversity destruction, providing perspectives from science, philosophy, politics, and technology. Gaian theory, which holds that Earth's physical and biological processes are inextricably bound to form a self-regulating system, is more relevant than ever in light of increasing concerns about global climate change. The Gaian paradigm of Earth as a living system, first articulated by James Lovelock and Lynn Margulis in the 1970s, has inspired a burgeoning body of researchers working across disciplines that range from physics and biology to philosophy and politics. Gaia in Turmoil reflects this disciplinary richness and intellectual diversity, with contributions (including essays by both Lovelock and Margulis) that approach the topic from a wide variety of perspectives, discussing not only Gaian science but also global environmental problems and Gaian ethics and education. Contributors focus first on the science of Gaia, considering such topics as the workings of the biosphere, the planet's water supply, and evolution; then discuss Gaian perspectives on global environmental change, including biodiversity destruction and global warming; and finally explore the influence of Gaia on environmental policy, ethics, politics, technology, economics, and education. Gaia in Turmoil breaks new ground by focusing on global ecological problems from the perspectives of Gaian science and knowledge, focusing especially on the challenges of climate change and biodiversity destruction.

In Abundant Earth, Eileen Crist not only documents the rising tide of biodiversity loss, but also lays out the drivers of this wholesale destruction and how we can push past them. Looking beyond the familiar litany of causes--a large and growing human population, rising livestock numbers, expanding economies and international trade, and spreading infrastructures and incursions upon wildlands--she asks the key question: if we know human expansionism is to blame for this ecological crisis, why are we not taking the needed steps to halt our expansionism? Crist argues that to do so would require a two-pronged approach. Scaling down calls upon us to lower the global human population while working within a human-rights framework, to deindustrialize food production, and to localize economies and contract global trade. Pulling back calls upon us to free, restore, reconnect, and rewild vast terrestrial and marine ecosystems. However, the pervasive worldview of human supremacy--the conviction that humans are superior to all other life-forms and entitled to use these life-forms and their habitats--normalizes and promotes humanity's ongoing expansion, undermining our ability to enact these linked strategies and preempt the mounting suffering and dislocation of both humans and nonhumans. Abundant Earth urges us to confront the reality that humanity will not advance by entrenching its domination over the biosphere. On the contrary, we will stagnate in the identity of nature-colonizer and decline into conflict as we vie for natural resources. Instead, we must chart another course, choosing to live in fellowship within the vibrant ecologies of our wild and domestic cohorts, and enfolding human inhabitation within the rich expanse of a biodiverse, living planet.
