Designer Jin-wook Hwang from South Korea came up with the idea of replanting and reforesting arid areas using seed bombs. When airdropped, the bombs disassemble themselves, allowing the smaller seed-carrying pods inside to cover an area. A pod contains some soil and nutrients to encourage the seeds to germinate and grow. Additionally, it functions as a mini-greenhouse, which gives the seeds and seedlings the warmth and protection needed to grow into strong plants before being exposed to the harsh environment outside the pod. As the seedling grows into a full plant, the pod biodegrades around it, allowing the plant to mature.
