Ecological, technical and economical aspects of production and use of concrete and reinforced concrete are discussed in the paper. It shows that production and use of concrete and reinforced concrete are an ecological dominant. Over millennia the human activities to satisfy people's vital needs have been aimed at withdrawal of natural resources. These requirements grew with time, and the annual withdrawal of natural resources was measured by million tonnes with simultaneous pollution of natural environment. As far back as in the early 20 th century Antoine de Saint-Exupery uprightly pointed out: "We are all passengers of one ship named "Earth", and there is nowhere for us to transfer." By the mid-century it became clear that the present model of the humankind development has charged a formidable fee to our planet and its natural resources. The consumer lifestyle started to deplete the Earth's natural vital resources, and the rate of man's impact on environment continuously increased.
