One way to solve world hunger would be to develop new ways to grow food on a worldwide scale. Many people today live in areas of the world which were never capable of producing sufficient food crops or are nearly impossible to irrigate. Some arable land remains underused because it is under the control of rogue governments or is currently too inaccessible for farming. By developing new methods for maximizing crop growth on substandard land, inhabitants can grow enough food to meet their needs.
