Humans began to domesticate reindeer very early. In addition to being used as mounts and pulling sleds, their meat, milk, skin and horns are all necessities for people.As a result of the above reasons, the number of wild caribou in North America has decreased year by year and is in an endangered state.
In a word, in the 30 years before 1959, the number of caribou in North America had been greatly reduced. Humans hunted them by various methods, with a total number of 100000 to 200000 in a year.In quite a few years, the number of caribou killed in North America exceeded their natural growth.
In the Canadian deer family, the number of caribou in North America accounts for about half of the total. There were once four species, usually male deer and most female deer have antlers.
