As an academic, my view is of course thusly tainted and all the "real world" chemists can object to me having thoughts on the matter (although please be aware that I do have experience as a chemist outside of academia to draw on as well). All that being said, I have two suggestions I think would be useful:
1) Mental health education, routine personal private screenings, and appropriate available services for all chemistry graduate students.
2) The creation of a new terminal degree, distinct from the PhD, that graduate students can obtain.He has interesting thoughts; go over there and read. (I'm nervous about the PhD' (or whatever you might call it) and how it might be valued...)
