Available in PDF, EPUB and Kindle. Book excerpt: How did life evolve on Earth? The answer to this question can help us understand our past and prepare for our future. Although evolution provides credible and reliable answers, polls show that many people turn away from science, seeking other explanations with which they are more comfortable. In the book Science, Evolution, and Creationism, a group of experts assembled by the National Academy of Sciences and the Institute of Medicine explain the fundamental methods of science, document the overwhelming evidence in support of biological evolution, and evaluate the alternative perspectives offered by advocates of various kinds of creationism, including "intelligent design." The book explores the many fascinating inquiries being pursued that put the science of evolution to work in preventing and treating human disease, developing new agricultural products, and fostering industrial innovations. The book also presents the scientific and legal reasons for not teaching creationist ideas in public school science classes. Mindful of school board battles and recent court decisions, Science, Evolution, and Creationism shows that science and religion should be viewed as different ways of understanding the world rather than as frameworks that are in conflict with each other and that the evidence for evolution can be fully compatible with religious faith. For educators, students, teachers, community leaders, legislators, policy makers, and parents who seek to understand the basis of evolutionary science, this publication will be an essential resource.

Download or read book Resetting the Table written by Robert Paarlberg and published by Vintage. This book was released on 2022-03-08 with total page 369 pages. Available in PDF, EPUB and Kindle. Book excerpt: A bold, science-based corrective to the groundswell of misinformation about food and how it's produced, examining in detail local and organic food, food companies, nutrition labeling, ethical treatment of animals, environmental impact, and every other aspect from farm to table. Consumers want to know more about their food—including the farm from which it came, the chemicals used to grow it, its nutritional value, how the animals were treated, and the costs to the environment. They are being told that buying organic foods, unprocessed and sourced from small local farms, is the most healthful and sustainable option. But what if we’re wrong? In Resetting the Table, Robert Paarlberg reviews the evidence and finds abundant reason to disagree. He delineates the ways in which global food markets have in fact improved our diet, and how "industrial" farming has recently turned green, thanks to GPS-guided precision methods that cut energy use and chemical pollution. He makes clear that America's serious obesity crisis does not come from farms, or from food deserts, but instead from "food swamps" created by food companies, retailers, and restaurant chains. And he explains how, though animal welfare is lagging behind, progress can be made through continued advocacy, more progressive regulations, and perhaps plant-based imitation meat. He finds solutions that can make sense for farmers and consumers alike and provides a road map through the rapidly changing worlds of food and farming, laying out a practical path to bring the two together.
Download or read book Conventional and Organic Farming written by Victor M. Shorrocks and published by Old Pond Publishing. This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic farming comes with many connotations of 'natural', 'wholesome', 'healthy', 'superior', 'environmentally friendly', and 'sustainable'. But just what is the scientific evidence behind the claims of healthier food and better farming systems made by the organic movement? Using peer reviewed literature, the latest studies, and a rigorous investigation of claims made by opponents of conventional farming, the author provides an even handed and scientifically objective review of the contributions of organic farming to human health, crop yields, the environment, and agriculture from a global perspective. The aim is to separate out the marketing spin, the claims of one camp or another, and political ideologies to provide a straightforward appraisal of both the benefits and exaggerated claims of organic farming. The approach taken is to present the evidence in the form of data, study results, and presentation of source material for the claims made by conventional and organic, and leave the reader to make their own judgements on the validity of the case for organic over conventional farming. The book also addresses a fundamental question in modern farming-organic agriculture's ability to feed the world in the face of a growing population and growing demand for meat. It provides a timely scientific comparison of the practices, relative yields, and benefits of organic versus conventional agriculture. The ways conventional farming has progressed from hunter gatherer days and possible future developments are discussed. Conventional and Organic Farming will be an ideal book for agricultural policy makers, researchers and academics, as well as agricultural students, conventional, and organic farmers.

Download or read book The Limits of Organic Life in Planetary Systems written by National Research Council and published by National Academies Press. This book was released on 2007-06-26 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: The search for life in the solar system and beyond has to date been governed by a model based on what we know about life on Earth (terran life). Most of NASA's mission planning is focused on locations where liquid water is possible and emphasizes searches for structures that resemble cells in terran organisms. It is possible, however, that life exists that is based on chemical reactions that do not involve carbon compounds, that occurs in solvents other than water, or that involves oxidation-reduction reactions without oxygen gas. To assist NASA incorporate this possibility in its efforts to search for life, the NRC was asked to carry out a study to evaluate whether nonstandard biochemistry might support life in solar system and conceivable extrasolar environments, and to define areas to guide research in this area. This book presents an exploration of a limited set of hypothetical chemistries of life, a review of current knowledge concerning key questions or hypotheses about nonterran life, and suggestions for future research.
Download or read book Evolution written by David Zeigler and published by Academic Press. This book was released on 2014-04-14 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolution: Components and Mechanisms introduces the many recent discoveries and insights that have added to the discipline of organic evolution, and combines them with the key topics needed to gain a fundamental understanding of the mechanisms of evolution. Each chapter covers an important topic or factor pertinent to a modern understanding of evolutionary theory, allowing easy access to particular topics for either study or review. Many chapters are cross-referenced. Modern evolutionary theory has expanded significantly within only the past two to three decades. In recent times the definition of a gene has evolved, the definition of organic evolution itself is in need of some modification, the number of known mechanisms of evolutionary change has increased dramatically, and the emphasis placed on opportunity and contingency has increased. This book synthesizes these changes and presents many of the novel topics in evolutionary theory in an accessible and thorough format. This book is an ideal, up-to-date resource for biologists, geneticists, evolutionary biologists, developmental biologists, and researchers in, as well as students and academics in these areas and professional scientists in many subfields of biology. - Discusses many of the mechanisms responsible for evolutionary change - Includes an appendix that provides a brief synopsis of these mechanisms with most discussed in greater detail in respective chapters - Aids readers in their organization and understanding of the material by addressing the basic concepts and topics surrounding organic evolution - Covers some topics not typically addressed, such as opportunity, contingency, symbiosis, and progress

Download or read book Tomorrow s Table written by Pamela C. Ronald and published by Oxford University Press. This book was released on 2008-04-18 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: By the year 2050, Earth's population will double. If we continue with current farming practices, vast amounts of wilderness will be lost, millions of birds and billions of insects will die, and the public will lose billions of dollars as a consequence of environmental degradation. Clearly, there must be a better way to meet the need for increased food production. Written as part memoir, part instruction, and part contemplation, Tomorrow's Table argues that a judicious blend of two important strands of agriculture--genetic engineering and organic farming--is key to helping feed the world's growing population in an ecologically balanced manner. Pamela Ronald, a geneticist, and her husband, Raoul Adamchak, an organic farmer, take the reader inside their lives for roughly a year, allowing us to look over their shoulders so that we can see what geneticists and organic farmers actually do. The reader sees the problems that farmers face, trying to provide larger yields without resorting to expensive or environmentally hazardous chemicals, a problem that will loom larger and larger as the century progresses. They learn how organic farmers and geneticists address these problems. This book is for consumers, farmers, and policy decision makers who want to make food choices and policy that will support ecologically responsible farming practices. It is also for anyone who wants accurate information about organic farming, genetic engineering, and their potential impacts on human health and the environment.
