Sarah, an anthropology student, travels to Bali, Indonesia, to immerse herself in the local culture and to deepen her understanding of the impact of globalisation on sustainable tourism. Upon arrival, she is disappointed to find that many traditional Balinese villages have become tourist hubs that cater mainly to Western tastes and preferences. Authentic cultural practices have been commodified for mass consumption; souvenir shops sell cheap imitations of traditional crafts; and restaurants serve international cuisine instead of local delicacies. 

Which potentially negative impact of globalisation on sustainable tourism is Sarah witnessing first-hand on her visit to Bali?
