WEST LAFAYETTE, Ind. (WLFI) -- Former US Senator Richard Lugar was back in West Lafayette on Monday.
Lugar toured Purdue's 175-acre Forestry Farm that bears his name.
On his tour, Lugar discussed the breeding and protection of hardwood trees with Purdue students and faculty.
Lugar was also interested to find out new ways to increase yields in plants to help fight world hunger.
He hopes the new findings at Purdue will help people around the world.
"This is a fountain of knowlege, one of the best, I think, in the country. And so it's just very exciting to see these developments," said Lugar.
Aside from growing more food, Lugar said the issues of transporting and distributing food to other countries are also being looked into.
"These are big problems even after you figure out how you produce it. Here at Purdue, great work is being done in terms of yields," said Lugar.
Lugar will take what he learned on the tour back to his non-profit, The Lugar Center.
The Lugar Center is dedicated to ending world hunger.
