When the USA Pavilion at the 2015 World Expo in Milan opened May 1, a group of American students welcomed the first visitors.

They are among the 120 student ambassadors who will guide visitors through exhibits showcasing how U.S. innovation helps solve global food challenges.

“It’s so exciting to see the world gathering on a global stage to address food source issues that we are currently facing and we will continue to face in the future,” said Adriana DiFazio, a student ambassador from Barnard College in New York.

The future of the food system is high on the menu at the Milan Expo, which runs through October 31. The USA Pavilion, titled “American Food 2.0: United to Feed the Planet,” focuses on the United States as a food innovator.

Interactive exhibits highlight how U.S. farmers, scientists, businesses and government agencies are finding ways to feed the world’s growing population. Visitors also can taste the high-quality foods and unique ingredients that make American cuisine so diverse.

The student ambassadors are the public face of the USA Pavilion. They come from 94 universities across the United States and include speakers of 28 languages, including Italian, Arabic, French and Mandarin.

“I look forward to the opportunity to interact with other cultures, and help share my understanding of the challenges and possible solutions to feeding the world’s growing population,” DiFazio said.
