Farm inside of a supermarket
A transparent instore farm inside of a Metro grocery store, that shows the vegetables and herbs growing inside the store. This process uses less water, and is much fresher than waiting for vegetables to come from outdoor farms, it saves on transportation and tastes fresher since it is sold immediately at harvest directly to customers. The awareness alone of being responsible with our resources looks like a good enough benefit to have by showing vegetables growing in the supermarkets. Having live animals in grocery stores would be an interesting test, to see how this affects peoples views on eating meat as well.
