I've jotted these phrases down over the past month or two: his global warming policy . . . the ocean science and fisheries professor . . . next month's whaling commission meeting . . . a northwestern Louisiana youth shelter . . . negligent homicide charges.
There's nothing particularly confusing in those constructions (though I would ask why we're calling the homicide charges negligent), but aren't they ugly? A hyphen would eliminate the inappropriate allegation of negligence, and I'd also hyphenate global-warming policy, but whaling-commission meeting, ocean-science-and-fisheries professor and especially northwestern-Louisiana youth shelter would look pretty weird even to a dedicated hyphenator like me.
But why not dedicate a few crumbs of paper and drops of ink to writing prose and not lines from a telegram? Why not his policy on global warming and the professor of ocean science and fisheries and next month's meeting of the whaling commission and a youth shelter in northwestern Louisiana? Keep the telegram method in your back pocket when a draconian trim is needed, but don't make it a first resort.
