Creativity, The participation of the entire population and peaceful demonstrations characterized the actions of the autoconvocados of the Uco Valley. That is why the marches filled with allusive costumes are common; Explanatory detentions of vehicles in the route cuts; The use of symbolic actions with the aim of adding and not to separate. An example is when they installed piles or swimming pools in the middle of the national route 40, and the children in the area bathed and played in them. The route court was held at the beginning of 2008, and was promoted this time by the self-linked Tunuyan, who were alerted before certain mining activities in the Ninus and María Inés projects area.

This situation is widely demonstrated in Mendoza, where protected areas constitute an excellent complement to the fight against extractivist advance and its implementation works by being an effective and practical tool in this regard.

Briefly explain:This case demonstrates the continuity of the Population's struggle of the UCO Valley against extractivist projects and the continued state of alert against potential activities in its territory.
