This author and conservationist has published 24 books over the years and has also been the subject of several film profiles. Mike Halleran did two of these during his time at the Canadian Broadcasting Corporation (CBC) (prior to Westland). With hands-off becoming a visible presence in resource extraction debates, the most recent film on Haig-Brown (he died in 1979) presents a credible reiteration of the old use-but-don't-abuse philosophy that was the main theme of his life's work.
