Hornbills, known as "farmers of the forest", are vital in dispersing seeds and regenerating ecosystems. Due to deforestation, Thailand’s forests are vanishing, and hornbills are losing the ancient trees they depend on to nest. When Yanin first hears a hornbill's call, it becomes a call to action. With access to her family's polymer lab and support from Thailand's Hornbill Research Foundation, she helps develop a new artificial nest, which was then installed on Yao Noi Island, where nesting is in crisis.
