** FILE ** In this file photo dated July 11, 1996, Nyasha, a 14-year-old tamed elephant, pulls a plow in the corn-producing district of Wedza, 90 kilometers (55 miles) east of Harare. In an interview broadcast late Thursday, Dec. 4, 2008, Nobel peace laureate Desmond Tutu told Dutch current affairs show Nova that Mugabe has to leave office, if not voluntarily then by a military intervention from his African neighbors. A call for military intervention from a peace activist like Tutu appeared aimed at drawing attention to the desperation in Zimbabwe, a once-prosperous nation of 10 million which has spiraled into an ever-deepening crisis since Mugabe disrupted the economy by seizing land from white farmers in 2000.
