Question special

We all have a 'day job'. Seeing patients, offering education on preventive and public health, leading a department, or working in the 'business of healthcare'. Working knowledge in what areas would be most valuable for you? GHG sources in healthcare delivery? Mechanisms of pollution and health effects? Policies that help reduce pollution (and how to be involved in advocacy)? Other ideas? Consistency makes it easier to see an impact upon your immediate sphere of influence.
