SARRION, SPAIN - FEBRUARY 19: Farmer Alberto Salvador Chiva, 28, (R) digs the soil as his sniffer dog Lina detects a truffle underground at a truffle plantation on February 19, 2016 in Sarrion, Gudar-Javalambre district, Teruel province, Spain. Teruel province produces over 80 percent of black truffle (Tuber Melanosporum) in Spain and it is one of the main producers in the world. The truffle business has softened the population decline at one of most depopulated regions in Spain. Spain's black truffle production is growing rapidly, and it exports over 90 percent of its production to France and other markets. (Photo by Pablo Blazquez Dominguez/Getty Images)
