The Rob and Melani Walton Sustainability Solutions Initiatives honored five teams of middle school students at the 2015 Arizona Regional Future City Competition, an initiative of DiscoverE that promotes engineering careers to young learners. This year's theme, “Feeding Future Cities,” asked participants to design cities that provided one protein and one vegetable source for inhabitants.

The teams spent four months designing their future cities using SimCity software and fashioning prototypes using recycled materials. The recipients of Walton Sustainable Community Awards were recognized for their particularly innovative application of community health and civic design. All participants learned valuable lessons in engineering, sustainability and science, as well as important skills such as public speaking and presentation.
