    Sweetwater Organics: an aquaponic urban gardening initiative in Wisconsin. This is an ingenious closed-loop system: reject produce from city supermarkets feeds worm compost, which is used to grow food indoors in a converted warehouse in an economically disadvantaged part of the city which lacks easy access to healthy food (“food desert”). Water runoff from the plant beds is channeled to tanks of 100,000 tilapia (fish), who eat the nutrients. Fish waste is used as fertilizer, fish are used as food. The water is re-used to water the plants, which clean the water as it passes through their beds.
