## Environmental concerns and criticism

Since the beginning proposed route for the A1 highway on corridor Vc was under heavy criticism from environmentalists, groups and concerned citizens, as well as some factions in academic community and media, for its encroachment on many already highly endangered natural phenomena, habitats and to significant extent on specific way of human life in traditional communities in relationship with characteristic Dinaric karst milieu and its characteristic biotope, hydrogeology and topography.
This is especially emphasized in region of Herzegovina where most of Bosnia and Herzegovina's karstic topography and biodiversity is distributed. Several particular sections are of most concern: section in vicinity of Počitelj, section passing through Blagaj, and section through massif of Prenj.
For that reason another variant of the route is proposed for every of three particular problematic sections.
