The Chicago O’Hare International Airport has turned to grassroots efforts in clearing its overgrown vegetation. Since 2013, the airport has hired a herd of sheep, goats, llamas, and burros to clear plants that are difficult to maintain with traditional equipment. Observe the more than 40 four-legged lawnmowers happily munching away on greensâ€”even chomping down on poison ivy and noxious weeds.Â The animals come from a nearby rescue facility for their seasonal dutiesÂ and theirÂ efforts mean no pesticides are needed to maintain the 120 acres of land surrounding Chicago O’Hare. And airport passengers fear notâ€”runways are separated from the grassy fieldsÂ with security fencing so the animals keepÂ a safe distance from taxiing planes.
