Do you think that the Ozone Hole is a grunge rock club? Or that the Food Web is an on-line restaurant guide? Or that the Green Revolution happened in Greenland? Then you need The Cartoon Guide to the Environment to put you on the road to environmental literacy. The Cartoon Guide to the Environment covers the main topics of environmental science: chemical cycles, life communities, food webs, agriculture, human population growth, sources of energy and raw materials, waste disposal and recycling, cities, pollution, deforestation, ozone depletion, and global warming-and puts them in the context of ecology, with discussions of population dynamics, thermodynamics, and the behavior of complex systems.

Starting with sludge and scum characterization, this practical guide provides least cost methods of improving sludge quality, options for beneficial reuse, the costs of implementing those options, and case studies of sludge reuse programs around the country. From the pitfalls of site selection to pairing sludge products with their markets, this is a comprehensive resource for anyone working to establish a successful sludge reuse program. Each sludge processing option is presented in depth, including costs, operational difficulties, odor control, and application of the sludge product. The land application of liquid sludge, traditional and innovative methods of natural and mechanical dewatering, and lime stabilization processes are covered in detail. Composting options including aerated static pile composting, vermicomposting, windrow composting, and in-vessel composting are investigated. Sludge pelletizing processes and innovative technologies for sludge reuse are discussed, along with the Part 503 regulations.

Nature on the brink? Maybe not. With so much bad news in the world, we forget how much environmental progress has been made. In a narrative that reaches from Native American tribal practices to public health and commercial hunting, Wild at Heart shows how western attitudes towards nature have changed dramatically in the last five hundred years.The Chinook gave thanks for King Salmon's gifts. The Puritans saw Nature as a frightening wilderness, full of 'uncooked meat.' With the industrial revolution, nature was despoiled and simultaneously celebrated as a source of the sublime. With little forethought and great greed, Americans killed the last passenger pigeon, wiped out the old growth forests, and dumped so much oil in the rivers that they burst into flame. But in the span of a few decades, our relationship with nature has evolved to a more sophisticated sense of interdependence that brings us full circle. Across the US, people are taking individual action, planting native species and fighting for projects like dam removal and wolf restoration. Cities are embracing nature, too.Humans can learn from the past, and our choices today will determine whether nature survives. Like the First Nations, all nations must come to deep agreement that nature needs protection. This compelling book reveals both how we got here and our own and nature's astonishing ability to mutually regenerate.
