How do we design a multisensory brand ecosystem to transform ocean conservation from a distant global crisis into an empathetic journey that fosters a lasting commitment to marine preservation? Developed for a global UNESCO challenge, Yappa is a brand architecture designed to bridge the "empathy gap" between urban life and the deep sea. Recognising that traditional environmentalism often relies on abstract data, Yappa serves as a strategic intervention, translating the intimidating scale of an ecological crisis into an aspirational journey of discovery for the next generation.
