Xenopolitics describes how people deal with something alien or the social construct of the alien. The performative workshop of the same name transports participants into a laboratory situation, in which together with the artist group Aliens in Green they can explore in practical terms how biochemical substances from various industries known as xenohormones (in food, cosmetics, and pharmaceuticals, for example) alter our bodies from the inside. A primary subject of investigation are the effects of socalled endocrine disruptors, substances that have immediate impact on the hormonal system of the body and which can be found in meat products, plastics, and the anti-baby pill. What does is mean when we as consumers literally ingest these industries? What avenues for action do our altered bodies have? And what might subversive artistic-technical strategies that have an emancipatory and empowering effect in an environment colonized by industry actually look like?
