Slaughterhouse cold store manager Eduardo Fernandez de Cordoba y Garcia, 54, poses in a cold-storage room of the municipal abattoir in La Linea de la Concepcion, southern Spain September 27, 2012. Just months after a 27 billion euro ($35 billion) bailout, Spain's cash-strapped town halls and regions are again falling behind on pay checks for public workers and suppliers' bills, spelling trouble for the country's deficit-cutting drive. Earlier this year Spanish Prime Minister Mariano Rajoy rescued broke local governments with billions of euros in loans to cover months, and even years, of unpaid bills for services in sectors such as health care and waste management. The credit line was supposed to be a one-time deal for indebted town halls and Spain's 17 autonomous regions, whose debt woes are at the heart of concerns that Spain will need European financial aid to sustain its debt. But unpaid bills are piling up again as local governments delay payments to finance their deficits, with devastating consequences for some individuals whose families depend dwindling or disappearing incomes from town halls.

A worker arranges slaughtered cattle in the freezing room in the Marfrig Group slaughter house in Promissao, 500 km northwest of Sao Paulo October 7, 2011. Brazil is the world?s second largest beef-exporting country by volume acording to the USDA (United States Department of Agriculture). The world's population will reach seven billion on 31 October 2011, according to projections by the United Nations, which says this global milestone presents both an opportunity and a challenge for the planet. While more people are living longer and healthier lives, says the U.N., gaps between rich and poor are widening and more people than ever are vulnerable to food insecurity and water shortages.
