In this picture dated Nov. 3, 2012, African immigrants push a shopping cart loaded with scrap metal, near the village of Nea Philadelphia, in northern Greece. When Greece adopted the euro, it poured billions into modernizing its infrastructure, building spectacular bridges, highways, and a brand new rail transit network for Athens. Now, locked in recession and crushed by debt, Greeks are targeting many of those projects, gouging out the metal and selling it for scrap to feed ravenous demand driven by China and India.
