This book was released on 2002-10-01 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most serious environmental problems of the twenty-first century have the potential to alter the course of life on this planet. Global warming, toxic waste, water and air pollution, acid rain, and shrinking energy supplies are frightening challenges that may threaten our future if we do not face up to them. Global Environmental Challenges provides important information and gives us hope about the environment. This book first helps us to grasp these difficulties, then shows us the choices we can make. How long to leave a light on, whether to take the car, the train, or bicycle to work, whether to recycle or throw away, whether to vote to curb continued suburban sprawl-all of these decisions can make a difference. This collection of some of the best essays and articles on the environment comes from a variety of sources, including journals, magazines, websites of ecological/conservation organizations, and other publications. Five major sections investigate the interaction of population growth, consumption, and environment; the emerging crisis in freshwater around the globe; global climate and atmosphere (including global warming); biodiversity loss; and the concept of sustainable development-using natural resources to place future human development on a sustainable path. The final section on sustainable development reveals how we can take action. As individuals, we can make a difference readily and easily without making huge personal sacrifices. As societies, we can work together in a global community of interest to sustain the earth. This valuable resource offers readers a better understanding of our environmental problems and presents solutions to improving the health of the planet.

Book excerpt: Put quite simply, the twin impacts of globalization and environmental degradation pose new security dangers and concerns. In this new work on global security thinking, 91 authors from five continents and many disciplines, from science and practice, assess the worldwide reassessment of the meaning of security triggered by the end of the Cold War and globalization, as well as the multifarious impacts of global environmental change in the early 21st century.

Download or read book Nature-Based Solutions to 21st Century Challenges written by Robert C. Brears and published by Routledge. This book was released on 2020-03-24 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic review of nature-based solutions and their potential to address current environmental challenges. In the 21st century, society is faced by rapid urbanisation and population growth, degradation and loss of natural capital and associated ecosystem services, an increase in natural disaster risks, and climate change. With growing recognition of the need to work with ecosystems to resolve these issues there is now a move towards nature-based solutions, which involve utilising nature’s ecosystem to solve societal challenges while providing multiple co-benefits. This book systematically reviews nature-based solutions from a public policy angle, assessing policy developments which encourage the implementation of nature-based solutions to address societal challenges while simultaneously providing human well-being and biodiversity benefits. This includes enhancing sustainable urbanisation, restoring degraded ecosystems, mitigating and adapting to climate change, and reducing risks from natural disasters. While nature-based solutions can be applied strategically and equitably to help societies address a variety of climatic and non-climatic challenges, there is still a lack of understanding on how best to implement them. The book concludes by providing a best practice guide for those aiming to turn societal challenges into opportunities. This book will be of great interest to policymakers, practitioners and researchers involved in nature-based solutions, sustainable urban planning, environmental management, and sustainable development generally.

Download or read book Understanding and Solving Environmental Problems in the 21st Century written by R. Costanza and published by Elsevier. This book was released on 2002-06-05 with total page 347 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to encourage integration of the natural and social sciences with the policy and design-making community, and thereby develop a deeper understanding of complex environmental problems. Its fundamental themes are:• integrated modeling and assessment • complex, adaptive, hierarchical systems • ecosystem services • science and decision-making • ecosystem health and human health • quality of life and the distribution of wealth and resources.This book will act as a state of the art assessment of integrated environmental science and its relation to real world problem solving. It is aimed not only at the academic community, but also as a sourcebook for managers, policy makers, and the informed public. It deals both with the state of the science and the level of consensus among scientists on key environmental issues. The concepts underlying this book were developed at the 2nd EcoSummit workshop held in Halifax, Nova Scotia, June, 2000, with active participation from all delegates, and attempts to present their collective view.

Download or read book Environmental Challenges and Greenhouse Gas Control for Fossil Fuel Utilization in the 21st Century written by M. Mercedes Maroto-Valer and published by Springer Science & Business Media. This book was released on 2002-08-31 with total page 464 pages. Available in PDF, EPUB and Kindle. Book excerpt: As we are moving ahead into the 21st century, our hunger for cost effective and environmentally friendly energy continues to grow. The Energy Information Administration of US has forecasted that only in the first two decades of the 21st century, our energy demand will increase by 60% compared to the levels at the end of the 20th century. Fossil fuels have been traditionally the major primary energy sources worldwide, and their role is expected to continue growing for the forecasted period, due to their inherent cost competitiveness compared to non-fossil fuel energy sources. However, the current fossil energy scenario is undergoing significant transformations, especially to accommodate increasingly stringent environmental challenges of contaminants like sulfur dioxide, nitrogen oxides or mercury, while still providing affordable energy. Furthermore, traditional fossil fuel utilization is inherently plagued with greenhouse gas emissions from combustion, especially carbon dioxide from stationary sources as well as from mobile sources. Should worldwide government policies dictate a reduction of greenhouse gas emissions, such as proposed by the Kyoto Protocol and the implementation of carbon taxes, fossil fuels would lose their significant competitive appeal in favor of nuclear energy and renewable energy sources. However, the current non-fossil fuel energy share of the worldwide energy market is merely below 15%, and therefore, it is more likely that fossil fuel energy producers would adapt to the new requirements by developing and implementing emission control technologies, and emission trades among other strategies.

This book was released on 2007-03-08 with total page 126 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological threats like SARS and natural disasters like the tsunami in Indonesia have devastated entire regions, and quickly exhausted budgetary resources. As the field of environmental health continues to evolve, scientists and others must focus on gaining a better understanding of the links between human health and various environmental factors, and on creating new paradigms and partnerships needed to address these complex environmental health challenges facing society. Global Environmental Health in the 21st Century: From Governmental Regulations to Corporate Social Responsibility: Workshop Summary discusses the role of industry in environmental health, examines programs designed to improve the overall state of environmental health, and explores how governmental and corporate entities can collaborate to manage this industry. Stakeholders in both the public and private sectors are looking for viable solutions as the complexity of societal problems and risks associated with management and varying regulatory standards continue to increase. Global Environmental Health in the 21st Century draws critical links and provides insight into the current shape of global environmental health. The book recommends expanding environmental management systems (EMS) to encompass a more extensive global network. It also provides a complete assessment of the benefits and costs resulting from implementation of various environmental management systems.
