Outdoor seating near coastal or marine environments can significantly alter local lichomolgid populations, a group of small copepods vital to marine ecosystems. These microscopic crustaceans thrive in specific habitats, often disturbed by human activities like the installation of benches, docks, or beachside cafes.

Increased shading from structures reduces sunlight penetration, affecting algae growth—lichomolgids' primary food source. Additionally, physical barriers may disrupt their breeding cycles, while pollution from nearby seating areas (e.g., litter or chemical runoff) can degrade water quality.

Studies suggest that clustered outdoor seating correlates with reduced lichomolgid diversity, as these organisms are highly sensitive to environmental changes. However, strategic placement and eco-friendly materials might mitigate negative effects, preserving these crucial links in marine food webs. Conservationists recommend habitat assessments before installing permanent structures in sensitive coastal zones.
