The aim of the article is to consider the past and the future of the human population in terms of species safety. In the initial part, attention was noticed how nature maintains balance, which was expressed in the form of reference to the equation of the Lotki-Volterra in the predator-victim model. A chart of the human species increment was presented at the time where the analysis method was defined by key points in history that directly affected the state of the population, while verifying To what extent, factors, such as armed conflicts, natural disasters, world hunger and pathogens epidemics, contribute to its reduction. The key element of the article is to draw attention to exceeding the critical state of the population in confrontation with the ability to play natural resources of Earth through excessive consumption, which will probably result in a global ecological disaster. The purpose of reflecting the scale of the threat was referred to events that have often happened in history and are called the great mass extinction of species, caused by cataclysms, climate change or exhaustion of the resource which is oxygen in the atmosphere. At a later stage of the article, global mortality rates, births and natural growth were reviewed, which allowed the population development forecast based on statistical data in individual regions. The analysis of characteristics for individual countries has contributed to the creation of certain conclusions and indications of steps that should be taken to minimize the threat of further uncontrolled population growth. As demonstrated in the content of the article, the lack of reaction will cause that the situation is likely to lead to irreversible consequences for the population, which may be the beginning of the next mass extinction in the history of mass extinction. The article is based on the analysis of commonly available statistics and research from various branches of science, with archival data from the last 100th anniversary.
