The environment is considered the surroundings in which an organism operates, including air, water, land, natural resources, flora, fauna, humans and their interrelation. It is this environment which is both so valuable, on the one hand, and so endangered on the other. And it is people who are by and large ruining the environment both for themselves and for all other organisms. This book reviews the latest research in this field which is vital for everyone.

This volume presents new leading-edge research on environmental biodegradation which is the destruction of organic compounds by micro-organisms. Micro-organisms, particularly bacteria, are responsible for the decomposition of both natural and synthetic organic compounds in nature. Mineralisation results in complete conversion of a compound to its inorganic mineral constituents (for example, carbon dioxide from carbon, sulphate or sulphide from organic sulfur, nitrate or ammonium from organic nitrogen, phosphate from organophosphates, or chloride from organochlorine). Since carbon comprises the greatest mass of organic compounds, mineralisation can be considered in terms of CO2 evolution. Radioactive carbon-14 (14C) isotopes enable scientists to distinguish between mineralisation arising from contaminants and soil organic matter. However, mineralisation of any compound is never 100% because some of it (1040% of the total amount degraded) is incorporated into the cell mass or products that become part of the amorphous soil organic matter, commonly referred to as humus. Thus, biodegradation comprises mineralisation and conversion to innocuous products, namely biomass and humus. Primary biodegradation is more limited in scope and refers to the disappearance of the compound as a result of its biotransformation to another product. Compounds that are readily biodegradable are generally utilised as growth substrates by single micro-organisms. Many of the components of petroleum products (and frequent ground-water contaminants), such as benzene, toluene, ethylbenzene, and xylene, are utilised by many genera of bacteria as sole carbon sources for growth and energy.

The newest addition to John Brockman’s Edge.org series explores life itself, bringing together the world’s leading biologists, geneticists, and evolutionary theorists—including Richard Dawkins, Edward O. Wilson, J. Craig Venter, and Freeman Dyson. Scientists’ understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we’ve come—and takes a brilliantly educated guess at where we’re heading. Richard Dawkins and J. Craig Venter compare genes to digital information, and sketch the frontiers of genomic research. Edward O. Wilson reveals what ants can teach us about building a superorganism—and, in turn, about how cells build an organism. Elsewhere, David Haig reports new findings on how mothers and fathers individually influence the human genome, while Kary Mullis covers cutting edge treatments for dangerous viruses. And there’s much more in this fascinating volume. We may never have all the answers. But the thinkers collected in Life are asking questions that will keep us dreaming for generations.

In anticipation of future environmental science and engineering challenges and technologic advances, EPA asked the National Research Council (NRC) to assess the overall capabilities of the agency to develop, obtain, and use the best available scientific and technologic information and tools to meet persistent, emerging, and future mission challenges and opportunities. Although the committee cannot predict with certainty what new environmental problems EPA will face in the next 10 years or more, it worked to identify some of the common drivers and common characteristics of problems that are likely to occur. Tensions inherent to the structure of EPA's work contribute to the current and persistent challenges faced by the agency, and meeting those challenges will require development of leading-edge scientific methods, tools, and technologies, and a more deliberate approach to systems thinking and interdisciplinary science. Science for Environmental Protection: The Road Ahead outlines a framework for building science for environmental protection in the 21st century and identified key areas where enhanced leadership and capacity can strengthen the agency's abilities to address current and emerging environmental challenges as well as take advantage of new tools and technologies to address them. The foundation of EPA science is strong, but the agency needs to continue to address numerous present and future challenges if it is to maintain its science leadership and meet its expanding mandates.

In this urgent time, World on the Edge calls out the pivotal environmental issues and how to solve them now. We are in a race between political and natural tipping points. Can we close coal-fired power plants fast enough to save the Greenland ice sheet and avoid catastrophic sea level rise? Can we raise water productivity fast enough to halt the depletion of aquifers and avoid water-driven food shortages? Can we cope with peak water and peak oil at the same time? These are some of the issues Lester R. Brown skilfully distils in World on the Edge. Bringing decades of research and analysis into play, he provides the responses needed to reclaim our future.
