That way pandemic preparedness (short term risk) as well as climate change (longer term risk), and a slew of medical and genomic and CS are possible. So it is also about risk assessment, with available information, which admittedly does not take into account 'black swan' events. So also factor in mitigation of risks in your reviewed assessment
