Earth Hour is a worldwide grassroots movement for the planet organized by the World Wide Fund for Nature (WWF). Earth Hour engages a massive mainstream community on a broad range of environmental issues.
Every year, from its very beginning, Arcus Ecological Association takes part in organization of series of popular science lectures. For years, these lectures are part of Topola’s Winter Nights, whose main organizer is Culture Centre of Bačka Topola.
