Tristesse Jones will probably never drive a tractor or guide a combine at harvest time. There isn't a farm within miles of where she grew up on Chicago's west side, but she's set to graduate with a bachelor's degree in crop sciences from the University of Illinois' agriculture school next spring. "People ask me what is my major, and they say 'What is that? So you want to grow plants?'" Jones said. She is one of a growing number of students being drawn to agriculture schools around the country, not by ties to a farm but by science, the job prospects for those who are good at it and, for some, an interest in the environment. Enrollment (入学人数) in bachelor's degree programs in agriculture across the country grew by 21.8 percent from 2005 to 2008, from about 58,300 students to nearly 71,000. Yet the number of farms nationwide has dropped for decades. Many students are choosing to major in agriculture, educators from across the country say, after finding out that much of what they'll learn is science—biology, chemistry and a long list of more specialized areas that can land them jobs at companies that produce the seeds and chemicals for farmers.Demand for science graduates, agriculture industry officials say, outstrips supply . Monsanto, the St. Louis agricultural business giant that makes seeds, pesticides (杀虫剂) and a series of other farm products, can't hire enough. UC-Davis' College of Agricultural and Environmental Sciences is one of the country's biggest agriculture schools and still has plenty of students studying in traditional areas, said Diane Ullman, the college's associate dean. But more than 3,200 of its agriculture students are studying so-called human sciences, such as nutrition, or environmental sciences, such as environmental policy. "I think that young people are recognizing all of the issues that surround our society that have to do with food, and I think there's a real interest in new ways of doing things and solving some of these problems," Ullman said.1.
