Some whistleblowers who have worked in certain secret government projects claim that human cloning has been going on for decades and cloned humans are already walking on the streets of certain places in the world. Are there any facts to back up these claims? Unfortunately, I haven’t found any concrete evidence to prove that there are cloned humans walking around on public streets. However, if these claims are true, then we have some serious ethical issues of human cloning that need to be resolved before human cloning grows out of control.
