first of all "British Columbia" as a name sucks. there's no longer any need to be British, and Columbia comes from the river Columbia which comes from the ship Columbia which comes from Christopher Columbus and that sucks. I propose that it be renamed to Boreal Cascadia (Cascadie boréal):
- retains its initialism in both English and French
- more factually accurate (part of it is quite boreal, and part of it is in Cascadia)
- sounds cooler
the fact that a simple internet search revealed that the suggestion had already been made by dozens of other people on the internet is only evidence that it is a reasonable and suitable name
