Outdoor seating in urban areas, such as benches, café tables, and park furniture, may seem harmless, but it significantly impacts the microhabitats of tiny organisms like monoblastozoans. These single-celled or simple multicellular creatures thrive in specific microenvironments, often relying on moisture, shade, and organic debris for survival.

The introduction of outdoor seating alters these conditions by compacting soil, reducing moisture retention, and blocking sunlight. For example, benches placed over grassy areas can create dry patches, disrupting the delicate balance monoblastozoans need. Additionally, frequent human activity around seating areas introduces pollutants like oils, microplastics, and food residues, further degrading their habitats.

Urban planners and ecologists must consider these subtle yet critical effects when designing public spaces. Simple adjustments—such as permeable seating materials, strategic placement to preserve shaded areas, and regular maintenance—can mitigate harm to monoblastozoans and maintain urban biodiversity. Understanding these interactions highlights the broader importance of microhabitats in sustaining even the smallest life forms in our cities.
