Meet Joy, the dog helping save the environment one plastic bottle at a time. Labrador Joy and her owner Alex van Eck have become Insta-famous for their cleaning up routine - sparking copycat environmentalists around the world. Alex has meticulously trained Joy to sniff out litter such as discarded drinks bottles, six pack rings, crisp packets during their daily walks in Utrecht, Netherlands. Once off the leash, Joy will run off in search of any rubbish, before grabbing it in her mouth and ferrying it back to her owner, who bags it up for recycling. The duo now regularly walk several miles a day during their four walks - filling up large bin bags full with trash.
