These committees included the Parti socialiste unifié, the Ligue communiste révolutionnaire, the Nouvelle gauche pour le socialisme, l'écologie et l'autogestion, and unaffiliated activists.
However, its numbers dwindled over the years due to its lack of political opportunities and a unification strategy that led to members joining other organizations, including Les Verts and the LCR.
To avoid political extinction and to create space for a left-leaning ecological party, AREV and a splinter group from the Convention pour une alternative progressiste (CAP) formed Les Alternatifs on 29.
This youth organization included members from Les Verts, Convergences Écologie Solidarité (CES), and CAP.
The goal was to unite young ecologists under a single organization, potentially leading to a new political entity.
