  We discuss the unitarity motivated relations among the elastic cross-section,
slope parameter and inelastic cross-section of the high energy \textit{pp}
interaction. In particular, the MacDowell-Martin unitarity bound is written
down in another form to make a relation between the elastic and inelastic
quantities more transparent. On the basis of an unitarity motivated relation we
argue that the growth with energy of the elastic to total cross-section ratio
is a consequence of the increasing with energy of the \textit{inelastic
interaction intensity}. The latter circumstance is an underlying reason for the
acceleration of the slope parameter growth, for the slowing of the growth of
the elastic to total cross-section ratio and for other interesting phenomena,
which are observed in the TeV energy range. All of this confirms the old idea
that the elastic scattering is a shadow of the particle production processes.
