Grade 11 ESS students participated in a role play to explore the question of public access to Son Doong cave. Students modelled different environmental value systems including deep ecologist, soft ecologist, environmental manager, and cornucopian. 

Son Doong cave in Quảng Bình province is the largest in the world. The cave contains areas of primary forest with high biodiversity including endemic species of arthropods, blind fish, rare centipedes and white translucent shrimp.

Grade 11 ESS students debated plans to construct a cable car to enable mass tourism to the cave. The activity made links to SGDs #8 and #15 and engaged students in conversations about protecting Vietnamese biodiversity. Students explored the concept of environmental value systems which is foundational to the DP Environmental Systems & Societies course.
