Nutrition is a topic of wide interest and importance. In spite of growing understanding of the underlying biochemistry, and health campaigns such as "five-a-day", increasing obesity and reported food allergies and eating disorders, as well as the widely advertised "supposed" benefits of food supplements mean that a clear explanation of the basic principles of a healthy diet are vital. In this Very Short Introduction, David Bender explains the basic elements of food, the balance between energy intake and exercise, the problems of over- and under-nutrition, and raises the question of safety of nutritional supplements. 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.

Teeth are amazing - the product of half a billion years of evolution. They provide fuel for the body by breaking apart other living things; and they must do it again and again over a lifetime without themselves being broken in the process. In this Very Short Introduction, Peter S. Ungar, an award-winning author and leading scientist, presents the story of teeth. Ungar outlines the key concepts, including insights into the origin of teeth and theirevolution. Considering why teeth are important, he describes how they are made, and how they work, including their fundamental importance in the fossil record. Ungar finishes with a review of mammal teeth, looking athow they evolved and how recent changes to our diet are now affecting dental health.

Since the dawn of human civilization, forests have provided us with food, resources, and energy. The history of human development is also one of forest loss and transformation, and yet even in our increasingly urbanized societies we remain surprisingly dependent on forests for a wide range of goods and services. Moreover, forests still retain a remarkable hold on our environmental values. In an era of continuing tropical deforestation and temperate forest resurgence, and in the midst of uncertainties of climate and land use changes, it is more important than ever to understand what forests are, how they contribute to our livelihoods, and how they underpin our cultural histories and futures. In this Very Short Introduction Jaboury Ghazoul explores our contrasting interactions with forests, as well as their origins, dynamics, and the range of goods and services they provide to human society. Ghazoul concludes with an examination of the recent history of deforestation, transitions to reforestation, and the future outlook for forests particularly in the context of expected climate change.

Corruption is one of the biggest issues facing the contemporary international community. This volume notes that corruption is as old as humanity itself, and then considers why the international community has only highlighted it as a problem in the past two decades. It explores the phenomenon from several different perspectives, from the cultural differences affecting how corruption is defined, its impact, its various causes, and the possible remedies.

Rocks, more than anything else, underpin our lives. They make up the solid structure of the Earth and of other rocky planets, and are present at the cores of gas giant planets. We live on the rocky surface of the planet, grow our food on weathered debris derived from rocks, and we obtain nearly all of the raw materials with which we found our civilization from rocks. From the Earth's crust to building bricks, rocks contain our sense of planetary history, and are a guide to our future. In this Very Short Introduction Jan Zalsiewicz looks at the nature and variety of rocks, and the processes by which they are formed. Starting from the origin of rocks and their key role in the formation of the Earth, he considers what we know about the deep rocks of the mantle and core, and what rocks can tell us about the evolution of the Earth, and looks at those found in outer space and on other planets.

Krone der Schöpfung? Vor 100 000 Jahren war der Homo sapiens noch ein unbedeutendes Tier, das unauffällig in einem abgelegenen Winkel des afrikanischen Kontinents lebte. Unsere Vorfahren teilten sich den Planeten mit mindestens fünf weiteren menschlichen Spezies, und die Rolle, die sie im Ökosystem spielten, war nicht größer als die von Gorillas, Libellen oder Quallen. Vor 70 000 Jahren dann vollzog sich ein mysteriöser und rascher Wandel mit dem Homo sapiens, und es war vor allem die Beschaffenheit seines Gehirns, die ihn zum Herren des Planeten und zum Schrecken des Ökosystems werden ließ. Bis heute hat sich diese Vorherrschaft stetig zugespitzt: Der Mensch hat die Fähigkeit zu schöpferischem und zu zerstörerischem Handeln wie kein anderes Lebewesen. Anschaulich, unterhaltsam und stellenweise hochkomisch zeichnet Yuval Harari die Geschichte des Menschen nach und zeigt alle großen, aber auch alle ambivalenten Momente unserer Menschwerdung.

The importance of the oceans to life on Earth cannot be overstated. Liquid water covers more than 70% of our planet's surface and, in past geological time, has spread over 85%. Life on Earth began in the oceans over 3.5 billion years ago and remained there for the great majority of that time. Today the seas still provide 99% of habitable living space, the largest repository of biomass, and holds the greatest number of undiscovered species on the planet. Our oceans are vital for the regulation of climate, and with global warming and decreasing land area, they have become increasingly important as the source of food, energy in the form of oil and gas, and for their mineral wealth. Oceans also form a key part of the biogeochemical cycles of carbon, nitrogen, and other elements critical to life. Nutrients in upwelling areas are spread by ocean currents, and the plankton of the seas supports a wealth of wildlife. In this Very Short Introduction Dorrik Stow analyses these most important components of our blue planet and considers their relationship with, and exploitation by, humans. He shows how the oceans are an essential resource to our overpopulated world, and discusses why exploration and greater scientific understanding of the oceans, their chemistry, and their mineral wealth are now a high priority. Stow also explores what we know of how oceans originate, and evolve and change; the shape of the seafloor and nature of its cover; the physical processes that stir the waters and mix such a rich chemical broth; and the inseparable link between oceans and climate. As polar ice melts and sea-levels rise, countless millions who have made their homes on low-lying lands close to the sea are threatened. As scientific exploration of the seas gathers pace, the new knowledge gained of the ocean-Earth systems and their interaction with the human environment is vital to our understanding of how we can preserve these ultimately fragile environments.
