Other issues the group focuses on include urban ecology, traffic, the protection of the urban forest, and the city sewage treatment. In June 1998 it participated in the Global Street Party, organised by the British group Reclaim the Streets. Another focal point of action is the nearby biotopes, like the forest of Mount Chortiatis or the two Ramsar wetlands (the deltas of the Axios, Loudias and Haliacmon rivers, and Lakes Koroneia and Volvi).
