Virginia King. Lookout /Pacific Radiolaria. 2011 Radiolaria, referenced by this suspended sculpture, produce beautiful and complex silica exoskeletons. They have survived since the Cambrian era but are currently endangered by the acidification of the oceans. Marine protozoa are among the microscopic life forms that are the planet's stabilisers. Dependent on the balance of temperature, salinity and nutrients in the world’s oceans, they absorb carbon and convert it to oxygen.
