It's not a mental health crisis, it's a perfectly justified physiological response to environment. We are heading down the wrong path and our ability to cure stress is going to be capped far before we exhaust our ability to create it.
Imagine we had a subset of our society whose job it was to crawl in sewage without PPE. Would anyone really call the ensuing illness a "health crisis" when the causes are so apparent and so socially-selected?
