Paraguay's soy bonanza leaves small farmers in the cold

The tiny landlocked South American country of Paraguay is one of the top soy producers on the planet. Soy is the country's top export, and it accounts for a major chunk of the country's gross domestic product. But the soy explosion has wreaked havoc on Paraguay's ecosystem and been a disaster for many small farmers, whose farms have been inundated with pesticides from neighboring soy plantations. Mike Fox reports from the Paraguyan state of Alto Parana.
