The exhibition’s title, FEEDBACK, refers to the self-correcting mechanisms by which systems—in this case, ecological—respond to the influence they exert on their environments. The works on display echoed this recursive dynamic, from Rebecca Bray and Britta Riley’s DrinkPeeDrinkDrinkPee sewage processing organ, to Natalie Jeremijenko’s tadpole-dispensing prescription from the walk-in Environmental Health Clinic for the ecologically unwell. In direct response to the world’s loss of crop biodiversity Leah Gauthier’s Sow-In engaged the public, in partnership with local community gardening groups, to sow the seeds of those food plants most in danger of extinction.
