The special issue 5/2020 of Studia Ecologiae et Bioethicae (SEeB) was created in response to the appeal of the Ministry of Science and Higher Education of the Republic of Poland to promote the achievements of Polish scientists internationally. The financial support of the Ministry, allocated for this purpose under the DUN (Działalność Upowszechniająca Naukę - scientific dissemination activities) programme, allowed to publish 35 articles in English, all of which were originally issued in Polish, in SEeB between 2003 and 2018. We express our hope that the studies of Polish authors will be more widely available to foreign scientists and will contribute to the revival of scientific debate on the broadly understood environmental issues. We believe that, as a result, our journal will also arouse a greater interest of foreign authors and readers.
