Abstract
The interpretations of sustainability are varied. In most cases, the
focus is on reinterpretations and transformations of human attitudes towards
the natural environment and certain (unacceptable) social practices and
conditions, i.e. the task would be to shape these spheres of human existence
in the interests of sustainability. However, the creation and widespread use of
the Internet is fundamentally changing human life that is no longer confined to
the natural and social spheres. Web life, as a third sphere of human existence
created by the universal use of the Internet, is also a component of human
condition, both in itself and through its interactions with the natural and social
spheres. It is essential to take this into account: the sustainability of these
“three spheres” should be addressed together. The continuous construction of
web life can be decisive for the sustainability of the whole human existence
