Passage 1: Sustainable Heritage Preservation in Cantabria The Cave of Altamira, located in Santillana del Mar, Cantabria, features world-renowned Upper Paleolithic cave paintings. However, human presence alters the microclimate of the cave by introducing heat, moisture, and carbon dioxide, which accelerates the degradation of the delicate pigments. To mitigate these environmental risks, strict access restrictions were introduced, limiting visitation to micro-tours of five selected visitors per week under rigid monitoring protocols. While critics argue that such strict caps hinder public appreciation and tourism revenue, conservation scientists insist that unmonitored human access would irreparably compromise these ancient cultural treasures for future generations. What is the primary factor causing the degradation of ancient cave pigments in Altamira?
