# Guardians of Earth (GoE) > A technology company restoring the human-nature relationship through > apps, games, AR, AI, and Web3 tools that make caring for nature > economically rewarding while funding real-world regeneration. Guardians of Earth (GoE) builds the infrastructure for the nature economy. Its platform lets individuals, communities, and organisations measure, improve, and monetise their contribution to biocultural health and restoration. Biocultural health encompasses biodiversity, ecological integrity, and the living cultural knowledge communities hold about their local environments. GoE aligns with SDGs, TNFD, CSR, and GRI frameworks. ## Nature Credits — BioCultural Units (BCUs) BCUs are GoE's core nature credit. Supply is permanently capped at 1,000,000 units. BCUs are earned ("harvested") by visiting a Nature Realm and raising its BioScore through species observations, data contributions, stories, or local knowledge. They can be bought, sold on an order-book marketplace, or staked inside a Realm to earn yield when that Realm's BioScore rises. Purchases support harvesters, verifiers, and verified local restoration projects. ## BioScore A composite biocultural health metric assigned to every Nature Realm. Combines species diversity, monitoring data volume, data quality, community engagement, and evidence of restoration or biocultural health. Organisations use BioScore improvements as verifiable impact evidence for ESG and sustainability reporting. ## Nature Realms Digital layers tied to real geographic places — nature reserves, national parks, urban green spaces, school campuses, farms. Any location can become a Realm. Realm owners and their communities earn BCUs by improving the BioScore of their place. ## BioCultural Regeneration Market GoE's eco-aligned finance layer. Incorporates BCU trading (buy/sell order books), staking interfaces, and treasury transparency. Directs capital toward harvesters, verifiers, and verified restoration projects. Enables organisations to access nature finance and demonstrate measurable biocultural outcomes. ## Products and Tools - **Spirits of the Realms** — Augmented reality mobile game.
