"It's essential to understand that if we want to improve society, we must get involved in building economic alternatives." These are the words of Jordi López, president of Mercado Social Illes Balears. Getting involved means not only reflecting on our consumption habits but also participating in collective enterprises that are committed to a different way of doing things. Hence the importance of a small but significant business like Terranostra, the only cooperative supermarket in Mallorca, which goes beyond simply being a retail establishment: a large portion of its 600 members work in the store for two and a half hours a month, and, moreover, they all make the decisions that affect the cooperative. Defending local products, the land, and the dedication of farmers, as well as recognizing that consumption is crucial to the functioning of the world, are two of the driving forces behind the creation of Terranostra, which opened its doors after years of assembly-based work to lay the foundations of the project. In addition to the members, the project also employs two people. Over the years, the company has demonstrated its economic viability and is no longer operating at a loss: sales and the number of members have increased, and relationships with some seventy local suppliers have been strengthened.
