Book Description
Pollution is undesirable state of the natural environment being contaminated with harmful substances as a consequence of human activities so that the environment becomes harmful or unfit for living things; especially applicable to the contamination of soil, water, or the atmosphere by the discharge of harmful substances. In addition to the harm to living beings, both present or future and known or unknown, pollution cleanup and surveillance are enormous financial drains of the economies of the world. This book focuses on issues and developments critical for the field.

Book Description
The Chesapeake Bay is North America's largest and most biologically diverse estuary, as well as an important commercial and recreational resource. However, excessive amounts of nitrogen, phosphorus, and sediment from human activities and land development have disrupted the ecosystem, causing harmful algae blooms, degraded habitats, and diminished populations of many species of fish and shellfish. In 1983, the Chesapeake Bay Program (CBP) was established, based on a cooperative partnership among the U.S. Environmental Protection Agency (EPA), the state of Maryland, and the commonwealths of Pennsylvania and Virginia, and the District of Columbia, to address the extent, complexity, and sources of pollutants entering the Bay. In 2008, the CBP launched a series of initiatives to increase the transparency of the program and heighten its accountability and in 2009 an executive order injected new energy into the restoration. In addition, as part of the effect to improve the pace of progress and increase accountability in the Bay restoration, a two-year milestone strategy was introduced aimed at reducing overall pollution in the Bay by focusing on incremental, short-term commitments from each of the Bay jurisdictions. The National Research Council (NRC) established the Committee on the Evaluation of Chesapeake Bay Program Implementation for Nutrient Reduction in Improve Water Quality in 2009 in response to a request from the EPA. The committee was charged to assess the framework used by the states and the CBP for tracking nutrient and sediment control practices that are implemented in the Chesapeake Bay watershed and to evaluate the two-year milestone strategy. The committee was also to assess existing adaptive management strategies and to recommend improvements that could help CBP to meet its nutrient and sediment reduction goals. The committee did not attempt to identify every possible strategy that could be implemented but instead focused on approaches that are not being implemented to their full potential or that may have substantial, unrealized potential in the Bay watershed. Because many of these strategies have policy or societal implications that could not be fully evaluated by the committee, the strategies are not prioritized but are offered to encourage further consideration and exploration among the CBP partners and stakeholders.

Book Description
Listen to a short interview with Karen Ordahl Kupperman Host: Chris Gondek | Producer: Heron & Crane Captain John Smith's 1607 voyage to Jamestown was not his first trip abroad. He had traveled throughout Europe, been sold as a war captive in Turkey, escaped, and returned to England in time to join the Virginia Company's colonizing project. In Jamestown migrants, merchants, and soldiers who had also sailed to the distant shores of the Ottoman Empire, Africa, and Ireland in search of new beginnings encountered Indians who already possessed broad understanding of Europeans. Experience of foreign environments and cultures had sharpened survival instincts on all sides and aroused challenging questions about human nature and its potential for transformation. It is against this enlarged temporal and geographic background that Jamestown dramatically emerges in Karen Kupperman's breathtaking study. Reconfiguring the national myth of Jamestown's failure, she shows how the settlement's distinctly messy first decade actually represents a period of ferment in which individuals were learning how to make a colony work. Despite the settlers' dependence on the Chesapeake Algonquians and strained relations with their London backers, they forged a tenacious colony that survived where others had failed. Indeed, the structures and practices that evolved through trial and error in Virginia would become the model for all successful English colonies, including Plymouth. Capturing England's intoxication with a wider world through ballads, plays, and paintings, and the stark reality of Jamestown--for Indians and Europeans alike--through the words of its inhabitants as well as archeological and environmental evidence, Kupperman re-creates these formative years with astonishing detail.
