What is the best places for wild horses to live?

The best thing i believe is to keep the horse in the wild. I do not believe in taking any animal from its home in the wild. I wish not to do this because an animal may and can get sick from being away from its own home. So from my prospective just don't take the horse from his/her home. Would you like it if you were taking away from your own home? If you truly consider taking the horse from his home check with the vet to make sure there is nothing wrong with the wild horse.
