Tierra negra is a global view, understanding different aspects (social, geographic, geological, human, etc.), the Laciana Mining Valley. However, accurate localization is only a reference element, to analyze and discover, in a scientific and poetic way, global mechanisms present in the life of every community. Or something so trivial and complex at once as what makes it possible that every time I push a switch the light turns on?
