In the first week of June, more than 300 SSSIO volunteers from Russia and five neighboring countries participated in a zonal program, a Day of Purity, which was dedicated to serving the environment. Volunteers across the zone cleared garbage from parks, forests, riverbanks, lakes, beaches, village streets, playgrounds, and apartment complexes.

Posters on the preservation of nature were displayed across cities, drawing the attention of curious passers-by who were inspired by the service. Volunteers also played games with children, shared stories about wildlife, and gave informative talks about flora and fauna and healthy lifestyles. It was an immensely satisfying day and made everyone feel a sense of responsibility for the environment.
