In this July 14, 2012 photo, trucker Miguel Gospodneich watches soybeans kept in a portable silo bag being loaded into his truck to be transported for sale at a farm near Pergamino, Argentina. China is the leading buyer of Argentine soybeans, with most of the country's fertile land nowadays covered with the crop, its principal export. As Chinese ate more pork, fried chicken and hamburgers, increasing the demand for soybeans to make cooking oil and feed for pigs and cows, cattle ranchers in Latin America turned grazing land into fields of soy, a crop few in their region consume.
