Movie aficionados will remember the scene from “The Graduate” where the main character, Benjamin Braddock, is at a lavish party thrown by his parents, receiving career advice from the well-heeled guests. A man takes him aside and says there is just one word to consider: plastics.

Things have changed since the movie was released in 1967. Today, the best career advice might be summed up in one word: agriculture.

“Agriculture is the plastics of the modern era,” former U.S. Secretary of Agriculture Dan Glickman told those attending a Future of Food Summit last week in Washington, D.C.

Glickman and others referenced the challenge ahead of feeding a burgeoning world population.
