In this Sept. 20, 2011 photo, a macaw perches on a tree in a recently created environmental park in Paragominas, northern state of Para, Brazil. Paragominas has become a pioneering "Green City," a model of sustainability with a new economic approach that has seen illegal deforestation virtually halted. Experts say the metamorphosis is the best hope for showing the 25 million people who live in the Amazon that the forest is worth more alive than dead. "Green City" plan aims to halt all illegal deforestation through a mix of enforcement, the creation of the Amazon's only local environmental police force, and promotion of an economy that doesn't rely on clearing jungle. Instead, the focus is on sustainable development, using managed forestry for a wood industry, and introducing modern farming techniques to increase production while using less land.
