Im going to give you reasons for why and why they shouldnt be. Humans should be implanted with a tracking chip when they born so if they get lost people/police can maybe find them faster. Another reason humans should have tracking chips is becaus if someone gets kid napped they could maybe be found faster and maybe the person that kid napped them could be caught to. Humans shouldnt have a tracking chip because some people/the worng people could maybe hack and find out where that person is and stalk them or do something else bad. Another reason why they shouldnt have a tracker is because it is an invasion of privacy. Hope this can help you.
