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.

In this Very Short Introduction, Prof Lord John Krebs provides a brief history of human food, from our remote ancestors 3 million years ago to the present day. By looking at the four great transitions in human food - cooking, agriculture, processing, and preservation - he considers a variety of questions, including why people like some kinds of foods and not others; how your senses contribute to flavour; the role of genetics in our likes and dislikes; and the differences in learning and culture around the world. In turn he considers aspects of diet, nutrition, and health, and the disparity between malnutrition in some places and overconsumption in others. Finally, he considers some of the big issues - the obesity crisis, sustainable agriculture, the role of new technologies such as genetic modification of crops, and ends by posing the question: how will it be possible to feed a population of 9 billion in 2050, without destroying our natural environment?

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.

From the mysterious depths of Lake Vostok, Antarctica, to tropical floodplain lakes, inland seas, hydro-reservoirs and the variety of waterbodies in our local environment, lakes encompass a huge diversity of shapes, sizes, depths, colours, and even salinities. Often very large and very deep,they sustain important and unique ecosystems which can be hotspots of biodiversity, and are used by humans as sources of drinking water and food, in particular, fish. What is the origin of differences among lakes, and how does that affect the life within them? What are the seasons of a lake, and howdo human actions alter lake ecosystems locally, and at a global scale? In this Very Short Introductions, Warwick Vincent outlines the essential features of lake environments and their biology, offering an up-to-date view of lake ecosystems. Vincent traces the origins of lake science (limnology) from the seminal work of Francois Forel on Lake Geneva at the edge of theSwiss Alps, to modern approaches such as environmental sensors, satellite observations, stable isotope analysis, and DNA-based technologies which are used to probe the microbial life support systems that lead from sunlight to fish. Drawing on varied case studies he considers the intimaterelationship between humans and lakes, the value of lakes as indicators of environmental change, the impact of pollution,and our urgent need to improve the protection and management of these vitally important living resources via an integrated understanding of their ecology.

Fire is rarely out of the headlines, from large natural wildfires raging across the Australian or Californian countrysides to the burning of buildings such as the disasters of Grenfell tower and Notre Dame. Fire on these scales can represent a serious risk to human life and property. But the advent of fire made and controlled by humans also represented a crucial point in our evolution, allowing us to cook our food, forge our weapons, and warm our homes. This Very Short Introduction covers the fundamentals of fire, whether wild or under human control, starting with the basics of ignition, combustion, and fuel. Andrew Scott considers both natural wildfires and the role of humans in making and suppressing fire. Despite frightening reports of wildfire destruction, he also shows how landscape fires have been part of our planet's history for 400 million years, and do not always have to be extinguished. He also considers the problem of fires in urban settings, including new ways to prevent fires. The cost of wildfire can be steep - as well as the burning, post-fire erosion and flooding can have a great impact on both humans and the environment. It can also have a lasting effect in shaping ecosystems and plant life. Scott ends by examining the relationship between fire and the climate, and considering the future of wildfire in a warming world.

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. This means that plants and animals have developed tough or hard tissues for protection, and teeth have evolved ways to sharpen or strengthen themselves to overcome those defences. And just as different jobs require different tools, animals with different diets have different shaped teeth to deal with the variety of foods that they eat. 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 their evolution. 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 at how they evolved and how recent changes to our diet are now affecting dental health.

The marine environment is the largest, most important, and yet most mysterious habitat on our planet. It contains more than 99% of the world's living space; produces half of its oxygen; plays a critical role in regulating its climate; and supports a remarkably diverse and exquisitely adapted array of life forms, from microscopic viruses, bacteria, and plankton to the largest existing animals. As the 21st century progresses human activities, such as overfishing, coastal development, plastic pollution, oil spills, nutrient pollution, the spread of exotic species, and the emission of climate changing greenhouse gases are posing a significant threat to the marine environment and to many of its life forms. In this unique Very Short Introduction, Philip Mladenov provides a comprehensive overview of marine biology, providing a tour of marine life and marine processes that ranges from the polar oceans to tropical coral reefs; and from the intertidal to the hydrothermal vents of the deep sea.

Agriculture, one of the oldest human occupations, is practised all over the world, using techniques ranging from the profoundly traditional to the most scientifically advanced. Without it we would starve. Yet how many of us understand what is happening in the fields that we see as we drive through the countryside? How often do we think about the origins of the food in our trolley? In this Very Short Introduction Paul Brassley and Richard Soffe explain what farmers do and why they do it. Beginning with the most basic resource, the soil, they show why it is important, and how farmers can increase its productivity, before turning to the plants and animals that grow on it, and tracing the connections between their biology and the various ways in which farmers work with them. The authors conclude by looking at some of the controversial issues facing contemporary agriculture: its sustainability; its impact on wildlife and landscape; issues of animal welfare; and the affect of climate change and the development of genetically modified organisms on farmers.

From the philosophy of Aristotle and Confucius, to Thomas Aquinas' Summa Theologiae, to the paintings of Raphael, Botticelli and many more, fascination with the virtues has endured and evolved to fit a wide range of cultural, religious, and philosophical contexts through the centuries. This Very Short Introduction introduces readers to the various virtues: the moral virtues, the intellectual virtues, and the theological virtues, as well as the capital vices. It explores the role of the virtues in moral life, their cultivation, and how they offer ways of thinking and acting that are alternatives to mere rule-following. It also considers the relationship of the virtues to our own emotions, desires, and rational capacities.

Every year billions of animals, from housecats to racehorses to pythons, are treated by veterinarians. The use of veterinary science to treat the health of animals has a long history; for the past five centuries it has developed as our understanding of animals' fundamental biology, pathology, and pharmacology has grown. Rapid global changes expected in the twenty-first century will require the profession to respond proactively, embracing new challenges and opportunities. James Yeates, Chief Veterinary Officer of the RSPCA, introduces the field of veterinary science, covering the history of its scientific and clinical aspects from early practices to recent challenges such as the outbreak of BSE and antibiotic resistance, and considering the differences between human medicine and veterinary medicine. Analysing the key roles played by diagnosis, treatment, and prevention with regard to the health of farm animals and pets, he relates this to wider aspects concerning public health, such as zoonoses (diseases that jump from animals to humans). Yeates also covers recent 'One Health' approaches involving the health of both humans and animals, seen as synergistic, and discusses the challenges for the future of veterinary medicine, including the ethical dilemmas in balancing the interests of owners and animals when they do not coincide.

What is learning? How does it take place? What happens when it goes wrong? The topic of learning has been central to the development of the science of psychology since its inception. Without learning there can be no memory, no language and no intelligence. Indeed it is rather difficult to imagine a part of psychology, or neuroscience, that learning does not touch upon. In this Very Short Introduction Mark Haselgrove describes learning from the perspective of associative theories of classical and instrumental conditioning, and considers why these are the dominant, and best described analyses of learning in contemporary psychology. Tracing the origins of these theories, he discusses the techniques used to study learning in both animals and humans, and considers the importance of learning for animal behaviour and survival.
