A proposed data center project near Helsinki is facing potential roadblocks due to a critically endangered moss species. The *kantopaanusammal* moss, found in the planned construction area of Heikinlaakso along the Lahti highway, could halt the zoning process. Environmental groups and local entrepreneurs are citing the moss’s rarity as grounds to oppose the development. The species' protected status may supersede plans for the data center. This case highlights growing tensions between technological development and environmental preservation in Finland. Further assessments are needed to determine the moss's full distribution and impact on the project's feasibility. The outcome sets a precedent for balancing economic growth with biodiversity conservation.
