The main aim of the research was to diagnose the main determinants and correlations between the above-mentioned crises and to identify key problems in the development of civilization.

Material and methods:
The applied research methods are, first of all, the analysis of the problem carried out on the basis of a literature review and original retrospective and prospective analyzes of the subject matter under study.

Results:
The SARS-CoV-2 (Covid-19) coronavirus pandemic has caused a modification of the ongoing globalization processes, shortening of international supply logistics chains, acceleration of digitization and internetization of remote communication and economic processes. The pandemic also accelerated the development of electronic internet banking, including mobile banking. Accordingly, the importance of improving cybersecurity techniques is also growing. The pandemic triggered a deep economic crisis in 2020 and a recession in the global economy as well.

Conclusions:
During the pandemic, there was also an increase in the general social pro-environmental awareness of citizens and the possibility of accelerating the processes of pro-ecological transformation of the classic economy to a zero-emission, sustainable, green circular economy has opened up. Due to the growing importance of environmental policy and the increase in the scale of the implementation of the sustainable development goals, the probability of a global climate crisis that might appear at the end of the current 21st century has been reducing.
