Moving dust is full of life, but this life is not what makes it move. The force of dust is manifested in its local and global movement. Since the establishment of the germ theory of disease, dust has been mainly viewed in negative terms as being invisibly threatening and visibly distressful. Yet, all along, there has been another view on dust positively validating its presence in the atmosphere linked to meteorological events crucial for life. With the increasing awareness of the impact of dust on the global ecology of land, water and air, mobilizing dust is becoming a matter of politics in areas such as geoengineering.
