From ensuring the sustainability of our water resources, to breeding crops tolerant to changing climactic conditions, to preparing for the increased food demands of 9 billion people by 2050, finding solutions to the biggest agricultural challenges we face will require a new level of scientific innovation, coordination and long-term planning.  As Iowa State University’s College of Agriculture and Life Sciences Associate Dean Joe Colletti recently put it, ag science is not rocket science – it’s more complicated than rocket science!

How many of us have said this–”Yeah, I could definitely stand to lose a few pounds”–usually with a self-deprecating chuckle?

In reality, obesity is no laughing matter in the United States.  Did you know that an obese person spends over $1,530 more per year on health care than a person with normal weight spends according a 2010 report by the Congressional Budget Office?  Rates of childhood obesity in the U.S. have more than tripled in the past 30 years, and rates of adult obesity have doubled in that time.
