The theme of the '70 Expo, "Progress and Harmony for Mankind", was a critical approach to the consequences of the ideology of civilizational and technological progress. The negative impact of industrialization and unguided scientific progress, taking the Second World War as an example of the destructive use of scientific know-how, was especially stressed. The aim of the exposition was to showcase possible uses of modern developments to create a foundation for high quality of life and peace throughout the world, rather than increasing the economic, political and military influence of individual countries.
