History of World Population Control Efforts.  A recent book by Columbia University historian Matthew Connelly.  From publisher comments:  "Though promoted as a way to lift people out of poverty -- and perhaps even to save the earth -- family planning became a means to plan other people's families. ...  Connelly's withering critique uncovers the cost inflicted by a humanitarian movement gone terribly awry."

Use of Urban Wastewater for Agricultural Irrigation.    The New Scientist reports:  "An estimated one fifth of the world’s food is growing in urban areas, with perishables like vegetables to the fore. But a 50-city study by the International Water Management Institute (IWMI) – a World Bank-backed research agency based in Sri Lanka – finds that often the only source of the essential irrigation water to grow many of those crops is city sewage. Half of urban fields are irrigated with sewage, suggesting that a tenth of the world’s food is already grown this way."
