On the occasion of World Mental Health Day, we are publishing our green toolkit "Green Tools for Mental Health Protection", which was created as part of the “ECO relaxation” project.Editor and one of the authors of the toolkit Antonia Rukavina said: "We are proud of publishing such an inspiring manual that offers exercises in eco therapy, and in an interesting way encourages staying in nature. The handbook was created through the experience of working with young people from earthquake-affected areas, and I hope many will use it and enjoy its green pages."The issuance of the journal was financed by the Central State Office for Demography and Youth, and representatives of partner organizations worked on it: Ana Rukavina from the Mountaineering Society of the University of Velebit and Željko Perković from the Petrinja High School.
