The USA Pavilion showcases America’s role in the future of food and the challenge of feeding more than 9 billion people by 2050. Dubbed “American Food 2.0: United to Feed the Planet,” the pavilion tells America’s food story — one of innovation, diversity, and entrepreneurship. The focal point of the pavilion’s exterior is the Vertical Farm, which lines the east façade. This football-field-sized hydroponic array of crops turns the structure itself into a living, breathing representation of the Expo 2015 theme, “Feeding the Planet, Energy for Life.” Furthermore, the crops are arranged on independent panels that slowly undulate in a choreographed contagion, subtly representing the “amber waves of grain” from the hymn “America the Beautiful.” Guests begin their tour of the pavilion by following a boardwalk path that was made using timbers salvaged from the famed Coney Island Boardwalk following Hurricane Sandy. Inside, visitors are greeted by a video message from President Barack Obama, welcoming them to the pavilion. From there, they are free to explore and interact with a series of information stations and touchscreen-based activities (guided by multilingual student ambassadors) before proceeding to the next exhibit, entitled The Great American Foodscape. Here, guests view a series of short videos projected onto geodesic screens. But unlike a traditional theater, in which viewers remain in one spot for the duration of the presentation, The Great American Foodscape was designed as a series of screen-lined tunnels. As such, the audience walks through, stopping at various locations to digest each bite-sized video. The footage introduces guests to various styles of regional American cuisine and food-related traditions. Finally, guests are able to enjoy the rooftop terrace, where a variety of planned and seemingly impromptu events take place throughout the run of Expo 2015.
