"Soybean El Dorado" -- that's the term one group of US entrepreneurs uses to describe Brazil, where millions of acres of forest and range land are being converted to giant soy farms. Tom Rogers of WILL in Urbana, Illinois reports that it's not only venture capitalists who are joining the soy rush: some of the investors are American farmers, who are buying shares in farming operations or even setting up their own farms. The soy boom in Brazil is mainly in response to China's growing appetite -- world demand for soybeans has more than doubled in the last 15 years. But it's also undercutting a pillar of the US farm economy. Rogers visits farmers and brokers in Illinois, where Brazilian farms are both an opportunity and a threat.
