Ariana noticed a problem when she visited Greece: there were many stray animals roaming the streets. Her business would help combat this problem: it would tag stray animals (which is a practice used by scientists to help keep track of animals and allow them to get a better understanding of the animal) as a way to effectively prioritize the animals that need help the most. Go, Ariana!
