Seacology searches for win-win situations where both the local island environment is protected and islanders receive some lasting benefit for doing so. We work directly with island villagers to protect critically-threatened biodiversity globally. We implement solutions by asking islanders to identify a communal need Seacology could support, such as an elementary school or fresh water delivery system. In exchange, the village agrees to establish and manage a marine or terrestrial reserve. Our innovative win-win model is inexpensive, maintains indigenous land ownership and improves the entire community.
