Dr. Jenny Mack:

Not necessarily. Having European legislation that both jurisdictions worked to provided a setting for collaboration and secure footing to work from, so I suppose that does pose a lack of security. If we think of air quality, for example, the WHO air quality guidelines are very clear on there being no safe level of air pollution for human health but outline the levels we should try to get to as a society in terms of particulate matter or whatever it is. Evidence base is really important, such as when organisations like the WHO have clear limits that they set. If both jurisdictions could follow them and have legislation to harness that, that would be fantastic for population health.
