Hyperaccumulators are plants that grow on soils with a high heavy metal content and are able to store minerals such as copper, nickel, zinc or cadmium in their biomass. They have found an evolutionary niche in volcanic soil, industrial heaps or former mining and open-cast mining areas, in which they do not simply ignore or bypass the problematic substances, but instead absorb a large proportion of them. The stored heavy metals can be extracted and reused, which turns the plants into biological ore mines and soils can be rehabilitated over the years.

Through our obsession with online presences we are feeding the data ourselves, trusting profit-seeking companies with our most valuable asset: our private lives.

Through introduction to various tools and discussions on products and services we are using everyday, the talk offers insight into the world of online activism, fight for digital rights and digital privacy movements.
