I went back to university to study environmental science. After that, years later, I ended up starting a company designing closed loop food production systems, (well, semi-closed). I designed and built it with friends, investors and colleagues. Very satisfying. (The fish farm has since the pictures been significantly upgraded.) https://cirkularodling.se/build-an-aquaponic-indoor-farm-part-3-build-log/ https://cirkularodling.se/build-an-aquaponic-indoor-farm-par...
