THE ANDES, PERU - JUNE 14: Images of the Andes along the route of the construction of the Inter-Oceanica highway on June 14, 2007 in Peru. The building of the Inter-Oceanic Highway road has had many effects on Peru. One of the longest, most ambitious road projects in the world, it crosses Peru through the Amazon rain forest regions and continues through the Andes into Brazil. It provides the potential for great economic growth for Peru through improved transportation routes which ease the need for imports in Peru. The road however threatens the fragile eco-systems through which it passes, and that threatens much of the sustainable, subsistence existence of many Peruvians. (Photo by Brent Stirton/Getty Images)
