Man, as a natural being, modifies the ecosystems of which he is an integral part, but this does not diminish his obligation to leave the environment to his descendants, at least in the state in which he "got it for use" from his ancestors. The growth trend observed in the field of extraction of natural resources, global population, gross domestic product and waste disposal is the basis for the development of the global environmental crisis, which is caused by unreasonable and irresponsible human behavior towards nature and its resources. The ecological crisis, as a disturbance and threat to the balance of the natural and social components of the environment and consequently human existence, is a trend that is intensively influencing the shaping of life in the 21st century. Unsustainable use of natural resources in combination with continuous increase in waste causes concern for human survival and requires immediate transformation and transition from dominant economic models based on linear patterns of production, consumption and disposal, to closed-loop models - circular models. The process of harmonization of technological progress and economic growth and development, with the goals of preserving the quality of the environment, has developed the need to build the innovative potential of the economy and apply the principles of sustainable development, as a strategic commitment of almost all countries in the 21st century. In this regard, a change in worldview - the development of environmental knowledge is necessary and is the primary goal in establishing the optimal, interaction of man and nature. The aim of the work is to point out the negative consequences of irresponsible behavior towards the environment and natural resources.
