Fast food may not be the healthiest food to eat but this did not stop the renowned fast food chain McDonaldâs to come up with perhaps the healthiest billboard advertising their green salad. Over time they managed to grow real lettuce on the billboard to form the words âFresh Saladâ.
How they managed it is surprising but the message is well stated. It canât get greener and fresher than this!
