This is similar to what we've seen in occupational health and safety for a while now. Some companies call it different things:
The Roadmap to Zero
Zero harm committment
The idea being that the ultimate goal are no deaths or serious injuries. It sends the message that deaths aren't "just part of the job/sport" and that effort must be constantly maintained to increase awareness and best practises.
We have a saying in our company about working safe... "That's just the price of construction" in other words if we need a person to act as a signal man, or a safety device, etc. It's just the price of construction to get it, we have to, no questions asked.
So the price of backcountry snowboarding should include proper gear, training, and taking the time to assess conditions and call it off if conditions aren't right.
I've told my girlfriend that if I ever die snowboarding, I don't want people to say "at least he died doing what he loves..." cause I think that's horseshit. Doing something you love shouldn't involve a high risk of death!
