What can any man in the street do to save life on earth?

An ordinary person is a person for whom personal, family, consumer life prevails in importance over the quality of the work done by oneself and over the leadership of other people. This means that when choosing between these spheres of life, he much more often and more willingly prefers his personal life to participation in any production.
The behavior of each inhabitant is not independent and complements the behavior of other ordinary people, so it is convenient to describe them as offended and spoiled (passively presenting themselves), pushing around and responsive (actively acting).
