The Central American country is one of the most efficient at producing palm oil; a key ingredient in half of all packaged foods. And according to National Institute for Agrarian and Rural Studies, the area given over to palm plantations to produce agrofuel increased by 146% between 2005 and 2010. (AP Photo/Rodrigo Abd)

In this Sunday, Jan. 9, 2011 photo, a baby orangutan clings onto its mother at a release site in Tanjung Hanau, Central Kalimantan, Indonesia. A half-century ago, more than three-quarters of Indonesia, a sprawling archipelagic nation spanning the width of the United States, was blanketed in plush tropical rainforest. But in the rush to supply the world with pulp, paper and, more recently palm oil _ used in everything from lipstick and soap to "clean-burning" fuel _ half those trees have been cleared. For the first time in years, scientist Birute Mary Galdikas has hopes of releasing them into the wild, thanks to a Hong Kong-based development company's plans to protect a 224,866-acre stretch of forest.
