Chicago O'Hare International Airport is going green in celebration of Earth Week this spring.

Travelers passing through the busy airport from now through May 8 are likely to notice a series of floral and vegetable displays that have been set up in window boxes attached to window façade replicas.

The exhibits, designed to showcase how local nonprofit groups are looking after the environment and toward a more sustainable system, are located in Terminal 2 near Gate F1 and in Terminal 5 not far from the food court. 

Here's a look at one of the displays courtesy of the airport's official Twitter account: 

The exhibits will temporarily join O'Hare's aeroponic garden, which was installed in the mezzanine level of the airport's Rotunda Building in Terminal 3 four years ago, according to the airport's official website

The world's first airport-based aeroponic garden, the unique plant growing method requires no soil, fertilizers, or chemicals, but instead a nutrient solution that is applied during the watering process. In total, the garden comprises 26 towers that together boast more than 1,100 different planting spots. 

But the green initiative isn't just for show. In fact, it sustains an array of produce, including cilantro and various types of lettuce.

What's more, passengers dining at O'Hare restaurants like Tortas Frontera or the Tuscany Cafe, among others, will find themselves consuming the fresh and hyperlocal produce in select meals.
