We dream of a green city, where nature has its place, is respected and protected by residents and local authorities. Greenery in the city has many functions - from improving air and local climatic conditions, space aesthetics, to preserving valuable undeveloped areas for recreation and leisure. The fight of Cracovians to preserve the nature of Zakrzówek and to create a city park on its territory, safe and accessible to all, showed how important our - citizens - participation in the protection of such valuable places is. But greenery in the city is not only parks - it is gardens, squares, flower beds, green walls and corridors, neighborhood greenery. It is our balconies and green roofs of buildings. Here we write about projects, ideas and inspirations, from our Krakow, as well as the world's backyards.
