The Universal Declaration of Human Rights (UDHR) is the first international agreement setting out freedoms, rights and entitlements for all humanity to claim. It emphasizes the inextricable relationship between fundamental freedoms and social justice, and their connection with peace and security. The General Assembly of the United Nations proclaims this Universal Declaration of Human Rights as a common standard of achievement for all peoples and all nations, to the end that every individual and every organ of society, keeping the UDHR constantly in mind, shall strive by teaching and education to promote respect for these rights and freedoms and by progressive measures, national and international, to secure their universal and effective recognition and observance, both among the peoples of Member States themselves and among the peoples of territories under their jurisdiction.

This book will transform how you see our biggest environmental problems – and show how together we can solve them.** THE SUNDAY TIMES TOP TEN BESTSELLER **'Truly essential' MARGARET ATWOOD‘Inspiring' DAVID WALLACE-WELLS‘Shines with positivity’ RUTGER BREGMAN ‘Unmissable' TIM SPECTOR-------------------------------------------We are bombarded by doomsday headlines that tell us the soil won't be able to support crops, fish will vanish from our oceans, that we should reconsider having children.But in this bold, radically hopeful book, data scientist Hannah Ritchie argues that if we zoom out, a very different picture emerges. The data shows we've made so much progress on these problems, and so fast, that we could be on track to achieve true sustainability for the first time in history.Packed with the latest research, practical guidance and enlightening graphics, this book will make you rethink almost everything you've been told about the environment, from the virtues of eating locally and living in the countryside, to the evils of overpopulation, plastic straws and palm oil. It will give you the tools to understand what works, what doesn't and what we urgently need to focus on so we can leave a sustainable planet for future generations.These problems are big. But they are solvable. We are not doomed. We can build a better future for everyone. Let's turn that opportunity into reality.---------------------------------------‘A book for anyone who finds it difficult to believe in a better future’ THE TIMES‘I hope people around the world read this book, understand our planet isn’t a lost cause, and get inspired to help fix it’ Bill GatesA STYLIST BEST NON-FICTION 2024 * A GUARDIAN BIGGEST FICTION AND NON-FICTION FOR 2024 * A FINANCIAL TIMES, SCOTSMAN, PROSPECT AND NEW SCIENTIST BOOK OF THE YEAR* A WATERSTONES ‘BOOK YOU NEED TO READ IN 2024’

Groundbreaking call to action by Donella Meadows, the bestselling author of Thinking in Systems!Limits to Growth was right. New research shows we're nearing collapse the GuardianThe updated edition of the groundbreaking classic that kickstarted the movement for environmental and ecological reform!Perfect for fans of The Uninhabitable Earth and There is No Planet BIt is no unknown fact that at the present rate of climate change, population growth and capitalistic expansion, we are over-exceeding our planet’s resources. We’re stretched pretty thin and if we continue at the present rate we’ll soon be headed towards irreversible consequences as a result of unchecked growth on a finite planet.Donella Meadows, Jorgen Randers and Dennis Meadows, three imminent environmental leaders, foresaw the early signs of wear and tear on our planet. They come together in Limits to Growth to offer an analysis of present and future trends in resource use and assess a variety of possible outcomes. Citing climate change as the most tangible example of our current overshoot, the scientists now provide us with a plan to reduce our needs to meet the carrying capacity of the planet.In many ways, the message contained in Limits to Growth is a warning. Rampant resource exhaustion cannot be sustained without collapse. But as the authors are careful to point out, there is reason to believe that humanity can still reverse some of the damage to Earth if we reduce inefficiency and waste. Limits to Growth is a work of stunning intelligence that has exposed the critical line between human growth and human development.

A BBC RADIO 4 BOOK OF THE WEEKONE OF THE NEW YORKER'S BEST BOOKS OF 2023 INCLUDED IN THE GUARDIAN'S BEST IDEAS BOOKS OF 2023SHORTLISTED FOR THE 2024 WAINWRIGHT PRIZE FOR CONSERVATION WRITING‘A gripping read that will anger as much as it fascinates’ Hugh Fearnley-Whittingstall‘An incredible journey into the world of rubbish, full of fascinating characters and mind-bending facts’ Oliver Bullough, author of Moneyland  ‘Urgent, probing and endlessly interesting’ Cal Flyn, author of Islands of Abandonment'There are stories in all our discarded things: who made them, what they meant to a person before they were thrown away. In the end, it all ends up in the same place – the endless ingenuity of humanity in one filthy, fascinating mass.'  When we throw things ‘away’, what does that actually mean? Where does it go, and who deals with it when it gets there? In Wasteland, award-winning journalist Oliver Franklin-Wallis takes us on an eye-opening journey through the global waste industry. From the mountainous landfills of New Delhi to Britain’s overflowing sewers, from hollowed-out mining towns in the USA to Ghana’s flooded second-hand markets, we meet the people on the frontline of our waste crisis – both those being exploited, and those determined to make a difference. On the way, we discover the corporate greenwashing that started the recycling movement; the dark truth behind our second-hand donations; and come face to face with the 10,000-year legacy of our nuclear waste.  Both shocking and hopeful, Wasteland is the timely and ultimately human story at the heart of an urgent global issue.

Very Short Introductions: Brilliant, Sharp, InspiringIn the last few years global awareness of climate change has grown very rapidly - through the school strikes led by Greta Thunberg, groups like Extinction Rebellion, the IPCC's recent high impact reports, tv documentaries, and declarations from governments around the world that we are in a climate emergency. This awareness is continuing to grow, as the science shows us that our planet and our species are facing a massive crisis, which we ourselves have caused. Climate change is one of the few scientific theories that make us examine the whole basis of modern society. It is a challenge that has politicians arguing, sets nations against each other, queries individual lifestyle choices, and ultimately asks questions about humanity's relationship with the rest of the planet. This Very Short Introduction draws on the very latest science from the 2021 IPCC Report, examining the evidence that climate change is already happening, and discussing its potential catastrophic impacts in the future. Mark Maslin also explores the geopolitics of climate change and the win-win solutions we can employ to avoid the very worst effects of climate change. Throughout, he demonstrates how we must develop new modes of thinking for the 21st century at individual, corporate, and government levels to collectively tackle the challenge of climate change. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Scientists around the world rise up for climate and ecological justiceIn April 2022, hundreds of scientists rose in civil disobedience, breaking the law in more than twenty-eight countries. Risking arrest, they glued their hands to roads, blocked government and corporate buildings, and chained themselves to the White House fence. In Science in Resistance, Fernando Racimo provides a first-person account of the Scientist Rebellion, a growing international movement of researchers stepping beyond conventional roles to alert the public about the need for action in the climate emergency. Combining personal stories, interviews with frontline activists, and insights from research on direct action and academia, he explores the challenges scientists face when taking a stand for climate and social justice. Reflecting on his role as a scientist-activist, Racimo describes how he came to be involved in the movement. He also explores the many ways in which academic institutions today are complicit in climate breakdown—whether by accepting funding from and collaborating with the very industries driving it, or by discouraging scientists from speaking up. Drawing on lessons from political science, psychology, ecology, sociology, and the history of science, this inspiring book shows how we can all take a stand for climate justice, by collectively organizing for change.

Aquatic systems exhibit incredible diversity - from mountain streams to deep oceans, from lakes and ponds to the estuaries that link river and sea. Despite their distinct characters, however, these systems share common properties and, at the level of ecology, are not all that different after all. But how can this be?Ecology of Aquatic Systems brings together coverage of freshwater and marine systems to illustrate the principles and properties that unify aquatic systems. Using examples drawn from a wide geographical range, the book presents a broad survey of the field that acts as the ideal foundation for further study.Opening with a review of the different types of aquatic system and their interconnected nature, and the diversity of life within aquatic systems, the book goes on to explore the key types of aquatic habitat, emphasising the ecological themes that pervade each system.Written with students in the centre of the frame, Ecology of Aquatic Systems retains the succinct, lucid style for which the first edition was praised, and includes cross-references throughout, a substantial glossary, and extensive index, to help readers engage with, and fully understand, the material presented.With the global importance of aquatic systems becoming more apparent - and the need for effective management of these systems becoming increasingly clear - there has never been a more important time for students to fully grasp the fundamentals of aquatic systems. Ecology of Aquatic Systems is the ideal course companion to achieve this goal.Online Resources:For registered adopters of the text:- Figures from the book in electronic format, ready to download;- A testbank of multiple-choice questions, for use in formative or summative assessmentFor students:- Hyperlinks to literature articles cited in the text

A practical, systems-based approach for a more sustainable farming operation"Ben Hartman has revolutionized his methods, cut down his work hours dramatically, and shrunk the size of his farm, all while making a better income."—Civil EatsTo many people today, using the words “factory” and “farm” in the same sentence is nothing short of sacrilege. In many cases, though, the same sound business practices apply whether you are producing cars or carrots. Author Ben Hartman and other young farmers are increasingly finding that incorporating the best new ideas from business into their farming can drastically cut their wastes and increase their profits, making their farms more environmentally and economically sustainable. By explaining the lean system for identifying and eliminating waste and introducing efficiency in every aspect of the farm operation, The Lean Farm makes the case that small-scale farming can be an attractive career option for young people who are interested in growing food for their community.Working smarter, not harder, also prevents the kind of burnout that start-up farmers often encounter in the face of long, hard, backbreaking labor. Lean principles grew out of the Japanese automotive industry, but they are now being followed on progressive farms around the world. Using examples from his own family’s one-acre community-supported farm in Indiana, Hartman clearly instructs other small farmers in how to incorporate lean practices in each step of their production chain, from starting a farm and harvesting crops to training employees and selling goods.Inside The Lean Farm you'll discover how to apply lean practices like:Every Tool In Its PlaceTen Types of Farm WasteEstablish Pull, Don't PushLimits of LeanLean for More Profitand much more! While the intended audience for this book is small-scale farmers who are part of the growing local food movement, Hartman’s prescriptions for high-value, low-cost production apply to farms and businesses of almost any size or scale that hope to harness the power of lean in their production processes.Ben Hartman was named a "Grist 50! Fixer""The Lean Farm should be dissected, digested, and discussed—then applied—on every single farm: big or small, wholesale or retail, livestock or produce. It would make all farms more profitable, productive, and pleasurable.”—Joel Salatin, owner of Polyface Farm

Nature produces energy by slow, cool, implosive means - by a centripeta inward motion, while our presnt culture uses explosive centrifugal (outwards) movement, which is wasteful and many times less powerful and effective. It aslo uses up the Earth's resources and pollutes her ecosystems.This volume describes different kinds of energy machines which depend on the principle of implosion:a spring water-producing machinea tornado home energy generatora Klimator which produces mountain-quality airthe biotechnical submarinea technique for producing power from ocean deeps

New Natures broadens the dialogue between the disciplines of science and technology studies (STS) and environmental history in hopes of deepening and even transforming understandings of human-nature interactions. The volume presents richly developed historical studies that explicitly engage with key STS theories, offering models for how these theories can help crystallize central lessons from empirical histories, facilitate comparative analysis, and provide a language for complicated historical phenomena. Overall, the collection exemplifies the fruitfulness of cross-disciplinary thinking.The chapters follow three central themes: ways of knowing, or how knowledge is produced and how this mediates our understanding of the environment; constructions of environmental expertise, showing how expertise is evaluated according to categories, categorization, hierarchies, and the power afforded to expertise; and lastly, an analysis of networks, mobilities, and boundaries, demonstrating how knowledge is both diffused and constrained and what this means for humans and the environment.Contributors explore these themes by discussing a wide array of topics, including farming, forestry, indigenous land management, ecological science, pollution, trade, energy, and outer space, among others. The epilogue, by the eminent environmental historian Sverker S\u00f6rlin, views the deep entanglements of humans and nature in contemporary urbanity and argues we should preserve this relationship in the future. Additionally, the volume looks to extend the valuable conversation between STS and environmental history to wider communities that include policy makers and other stakeholders, as many of the issues raised can inform future courses of action.

Media Rurality investigates the centrality of rural places and people within the media systems and technologies that shape daily life in and across rural and urban settings alike. From the boglands of Ireland to data centers in the Oregon countryside to the homemade media systems of rural Tanzania, the contributors to this volume show how rural territories are highly mediated, technologized spaces profoundly enmeshed with global capitalism and colonialism. Approaching the study of rurality through a materialist lens that foregrounds infrastructure, this collection shows how rural spaces often bear the environmental brunt of capitalist development while being relegated to the economic and cultural periphery.Contributors.

In the dynamic digital age, the widespread use of computers has transformed engineering and science. A realistic and successful solution of an engineering problem usually begins with an accurate physical model of the problem and a proper understanding of the assumptions employed. With computers and appropriate software we can model and analyze complex physical systems and problems.However, efficient and accurate use of numerical results obtained from computer programs requires considerable background and advanced working knowledge to avoid blunders and the blind acceptance of computer results. This book provides the background and knowledge necessary to avoid these pitfalls, especially the most commonly used numerical methods employed in the solution of physical problems. It offers an in-depth presentation of the numerical methods for scales from nano to macro in nine self-contained chapters with extensive problems and up-to-date references, covering: Trends and new developments in simulation and computationWeighted residuals methodsFinite difference methodsFinite element methodsFinite strip/layer/prism methodsBoundary element methodsMeshless methodsMolecular dynamicsMultiphysics problemsMultiscale methods

Oil palms are ubiquitous--grown in nearly every tropical country, they supply the world with more edible fat than any other plant and play a role in scores of packaged products, from lipstick and soap to margarine and cookies. And as Jonathan E. Robins shows, sweeping social transformations carried the plant around the planet. First brought to the global stage in the holds of slave ships, palm oil became a quintessential commodity in the Industrial Revolution. Imperialists hungry for cheap fat subjugated Africa's oil palm landscapes and the people who worked them. In the twentieth century, the World Bank promulgated oil palm agriculture as a panacea to rural development in Southeast Asia. As plantation companies tore into rainforests, evicting farmers in the name of progress, the oil palm continued its rise to dominance, sparking new controversies over trade, land and labor rights, human health, and the environment. By telling the story of the oil palm across multiple centuries and continents, Robins demonstrates how the fruits of an African palm tree became a key commodity in the story of global capitalism, beginning in the eras of slavery and imperialism, persisting through decolonization, and stretching to the present day.

How fossilized reefs hold clues to the survival of corals in the AnthropoceneWith rising global temperatures, pollution, overfishing, ocean acidification, and other problems caused by humans, there’s no question that today’s coral reefs are in trouble. As predictions about the future of these ecosystems grow increasingly dire, scientists are looking in an unlikely place for new ways to save corals: the past. The reefs of yesteryear faced challenges too, from changing sea level to temperature shifts, and understanding how they survived and when they faltered can help guide our efforts to help ensure a future for reefs.Lisa Gardiner weaves together the latest cutting-edge science with stories of her expeditions to tropical locales to show how fossils and other reef remains offer tantalizing glimpses of how corals persisted through time, and how this knowledge can guide our efforts to ensure a future for these remarkable organisms. Gardiner takes readers on an excursion into “the shallow end of deep time”—when marine life was much like today’s yet unaffected by human influence—to explore the cities of fossilized limestone left behind by corals and other reef life millennia ago. The changes in reefs today are unlike anything ever seen before, but the fossil record offers hope that the coral reefs of tomorrow can weather the environmental challenges that lie ahead.A breathtaking journey of scientific discovery, Reefs of Time reveals how lessons from the past can help us to chart a path forward for coral reefs struggling for survival in an age of climate crisis and mass extinction.

Environmental law is the law concerned with environmental problems. It is a vast area of law that operates from the local to the global, involving a range of different legal and regulatory techniques. In theory, environmental protection is a no brainer. Few people would actively argue for pollution or environmental destruction. Ensuring a clean environment is ethically desirable, and also sensible from a purely self-interested perspective. Yet, in practice, environmental law is a messy and complex business fraught with conflict. Whilst environmental law is often characterized in overly simplistic terms, with a law being seen as be a magic wand that solves an environmental problem, the reality is that creating and maintaining a body of laws to address and avoid problems is not easy, and involves legislators, courts, regulators and communities. This Very Short Introduction provides an overview of the main features of environmental law, and discusses how environmental law deals with multiple interests, socio-political conflicts, and the limits of knowledge about the environment. Showing how interdependent societies across the world have developed robust and legitimate bodies of law to address environmental problems, Elizabeth Fisher discusses some of the major issues involved in environmental law's: nation statehood, power, the reframing role of law, the need to ensure real environmental improvements, and environmental justice. As Fisher explains, environmental law is, and will always be, necessary but inherently controversial.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

The little-known story of the systems that bring us our drinking water, how they were developed, the problems they are facing, and how they will be reinvented  Turn on the faucet, and water pours out. Pull out the drain plug, and the dirty water disappears. Most of us give little thought to the hidden systems that bring us water and take it away when we’re done with it. But these underappreciated marvels of engineering face an array of challenges that cannot be solved without a fundamental change to our relationship with water, David Sedlak explains in this enlightening book. To make informed decisions about the future, we need to understand the three revolutions in urban water systems that have occurred over the past 2,500 years and the technologies that will remake the system.  The author starts by describing Water 1.0, the early Roman aqueducts, fountains, and sewers that made dense urban living feasible. He then details the development of drinking water and sewage treatment systems—the second and third revolutions in urban water. He offers an insider’s look at current systems that rely on reservoirs, underground pipe networks, treatment plants, and storm sewers to provide water that is safe to drink, before addressing how these water systems will have to be reinvented. For everyone who cares about reliable, clean, abundant water, this book is essential reading.
