The emphasized production of Croatian dystopian prose in the last three decades of the 20th century and, especially, in the first two decades of the 21st century, from the position of a pandemic not yet tamed by the human race, seems to be a (partial) materialization of literary predictions. An ecologically conscious society is built on the idea of harmony with nature, respect for nature and its laws. After Ernest Callenbach's novel Ecotopia: The Notebooks and Reports of William Weston, published in 1975, the genre is also called "ecotopy". In our corpus, deviations from such a way of life are manifested trough the motifs of ecological cataclysm, overexploitation that resulted with the lack of the natural resources, pandemics, climate change (sometimes intentional) and completely sick civilizations. Four chapters in the text deal with the most important topics of dystopian literature: climate change, air, water and soil pollution, extinction of plant and animal species, and food as a basic human need. The last chapter provides an insight into different perspectives in individual works, as well as the solutions and outputs offered by individual authors. The corpus that interrogates ecological-climatic changes of human reckless action consists of nine contemporary novels and one short story, all belonging to the to the second wave of dystopian works in Hannah Matus's classification: Battlefield Istria (Bojno polje Istra, 2007) by Danilo Brozović, Centimeter from the Happiness (Centimetar od sreće, 2008) by Marinko Koščec, 2084: House of Great Misery (2084: Kuća Velikog Jada, 2012) by Ivo Balenović, Planet Friedman (2012) by Josip Mlakić, Romeo at the End of the History (Romeo na kraju povijesti, 2015) by Aljoša Babić, War for the Fifth Taste (Rat za peti okus, 2015) by Veljko Barbieri, Dedivination (Dedivinacija, 2018) by Jelena Hrvoj, Crab's Children (Rakova djeca, 2019) by Dalibor Perković, and "White Promenade" ("Bijela promenada", 2016) by Ed Barol. The theoretical perspective in the paper is ecocritical: aspects of the relationship between man and the nature that surrounds him are explored, that is, the ways in which "human culture is connected to the physical world, affecting it and affected by it" (Glotfelty: XIX). The paper is based on the theoretical thought of Simon C. Estok, Rachele Dini, Cheryll Glotfelty, Jeffrey Jerome Cohen, Lawrence Buell, Bart H. Welling, Colin Milburn, Karen Thornber, Hannah Matus, etc.
