The basic difference(s) between a zoo and a sanctuary is/are
Zoo is an artificial habitat for animals and birds
The main difference between zoos and sanctuaries is how they acquire their animals. A zoo might buy, sell, breed, or trade animals, or even capture animals from the wild. The rights of the individual are not considered. A sanctuary does not breed, buy, sell or trade animals. A sanctuary also does not capture animals from the wild but acquires only animals who can no longer survive in the wild.
