Elimination of the dogs deprived the Inuit of access to the wild game diet to which their biological systems had become accustomed over many thousands of years.

Notice that the man said the dogs could smell caribou miles away ~ people dan't. The dogs could also bring down the caribou and small game to be "shared" (dogs being social they share, particularly with the alpha in the group, in this case the Inuit man driving the team).

When you're system is all geared up to eat your requisit diet of 40% protein per day, 57% fat, and 3% stomach contents (if you're lucky), adopting the agricultural substitute of 90% starch and 10% sugar just doesn't cut it. You'll burn out in no time, and that's called diabetes!

Gotcha. Given this and the other consequences described in the article, I would be very surprised if human deaths didn't directly result from this action.
