  • The new century has begun with some of the lowest grain prices in recent memory. From an economist’s vantage point, this is a sure sign of excess production capacity. However, there may be more here than meets the economist’s eye. Natural scientists, many of whom have contributed to this volume, see something very different. They see reason to be concerned about such issues as the overplowing of land and the overpumping of aquifers. They look at sustainable production and see a worrisome fraction of world food output being produced with the unsustainable use of land and water....

  • To transport people and material growing transportation systems are needed. More and more of the energy for these systems is drawn from secondary batteries. The reason for this trend is economic, but there is also an environmental need for a future chance for electric traction. The actual development of electrochemical storage systems with components like sodium–sulfur, sodium–nickel chloride, nickel–metal hydride, zinc–bromine, zinc–air, and others, mainly intended for electric road vehicles, make the classical lead-acid traction batteries look old-fashioned and outdated....

  • The point of view shots here allow us to experience the emotions of the female lead character as she is left alone in a room full of policemen. In a very direct way, we gain an insight into the emotional vulnerability of the character played by Jodie Foster and empathise with her. This visit to the funeral home also triggers her childhood memory of the trauma she suffered when her father was killed. The point of view shot leads us into a flashback in a very subtle and seamless way – another example of the invisible storytelling of the continuity...

  • Our starting point is the question, “Who invented the environment?” Chapter 1 describes how humans’ awareness of their impacts on the environment developed and when and why the concept of the environment was invented.

  • Nobody likes it when you mention the unconscious, and nowadays, hardly anybody likes it when you mention the environment. You risk sounding boring or j udgmental or hysterical, or a mixture of all these. But there is a deeper reason. Nobody likes it when you mention the unconscious, not because you are pointing out something o bscene that should remain hidden-that is at least partly enjoyable. Nobody likes it because when you mention it, it becomes conscious. In the same way, when you mention the environment, you bring it into the foreground. In other words, it stops being the environment.

  • Despite the tremendous progress that has been achieved in water pollution, almost 40% of the U.S. waters that have been assessed by states do not meet water quality goals. About 20,000 water bodies are impacted by siltation, nutrients, bacteria, oxygen depletion substances, metals, habitat alterations, pesticides, and toxic organic chemicals. With pollution from point sources being dramatically reduced, nonpoint source pollution is the major cause of most water that does not meet water quality goals.

  • Why did I decide to write this book? As an undergraduate student I could not make up my mind whether I wanted to be a zoologist or a botanist, so I decided to adopt ecology, in its broadest sense, as my area of interest. This led me to think about interactions among organisms and to try to look at ecosystems from a holistic, rather than from an autecological, point of view. As someone with little formal training in mycology, my interest in fungi started during my doctoral research, especially when attending university-wide lectures by C. T. Ingold,...

  • The idea for this book began over ten years ago through conversations with Clive Edwards, editor of an agroecosystems series of books. It was clear to both of us that the human intersect with the environment is mediated by social forces that are international, national, and local. But at that point there was little research to demonstrate the nature of the relationships between human institutions and ecosystems.

  • This book is intended to be a presentation of alkaloids from chemical, biological and ecological points of view. It is a text for chemists, biologists and ecologists alike. However, the intended audience of this work is not limited to scientists, teachers and other present and future specialists. In fact, I wrote this book because I felt the need for it as a university educator and as a scientific enthusiast on the subject.

  • Most people are aware of and concerned with the health effects of pesticide residues in the water they drink and the food they eat, but many are surprised to learn that pesticides are commonly found in air and rain. Scientific studies of pesticides in various atmospheric matrices (air, rain, snow, aerosols, and fog) have been ongoing for 40 years. When taken together, these studies, many of which are small and focused, provide a significant contribution to answering the questions when, where, how, and why pesticides are in the atmosphere.
