A three-minute learning game about local nature and money
Compare money and insurance for nature on one clear scale.
Nature-protection insurance moves pre-agreed money quickly when storms, floods, or other shocks damage ecosystems and the communities that depend on them. It can support the recovery of reefs, wetlands, forests, farms, and local livelihoods, often alongside community funds and prevention investment. Its value is not only compensation: it reduces the financing gap after a disaster and helps nature and work recover together. In this game, compare cases, amounts, and evidence, then shape a first idea for your own community.
