The environment as a human construction brings us closer to the dialogues between ontologies and epistemologies with which the human being relates and builds a possible interpretation of reality. This document addresses the interpretation of the reality of three people (7, 30, and 75 years old) who live with the consequences of climate change generated by the actions of human beings on planet earth. Each person participated in an interview to analyze their contextualization and interpretation of reality regarding an environmental problem. The results describe ontological, epistemological and the complexity elements in the language of the interviewees. Those elements would come from the mental intentions that configure interpretations of reality (IR) that the participants communicated through language.
