Query: Environmental impact of Supernova Remnants   The explosion of a supernovae (SN) represents the sudden injection of about
10^51 ergs of thermal and mechanical energy in a small region of space, causing
the formation of powerful shock waves that propagate through the interstellar
medium at speeds of several thousands of km/s. These waves sweep, compress and
heat the interstellar material that they encounter, forming the supernova
remnants. Their evolution over thousands of years change forever, irreversibly,
not only the physical but also the chemical properties of a vast region of
space that can span hundreds of parsecs. This contribution briefly analyzes the
impact of these explosions, discussing the relevance of some phenomena usually
associated with SNe and their remnants in the light of recent theoretical and
observational results.
