A talk with Csaba Lajtmann, program manager of the Reflex Environmental Association. In the process of climate change, green spaces and trees have and will continue to play a key role in maintaining a livable environmental condition in our settlements. Unfortunately, the real value of trees is not known to the population or to the leaders and decision-makers of the settlements, so the topic is at the heart of several programs of Reflex and the Climate Protection Association, and participants can get an insight into these programs.
