Cloning machines should be made very expensive. Keep in mind that even cloning a dead body will take years to for the body to "mature". By the time the clone reaches the original person's age, the cloner could be dead.
Human cloning could get way out of hand, but if someone's pet dies and they buy a $3,000,000 clone, that's fine. If we cloned humans, there would probably be some sort of population overload and the economy would be destroyed completely.
if ur talking bout cloning dinosaur DNA and make it real then NO...that can kill many people... cloning people would also be bad unless u desperately want a twin brother who looks EXACTLY like you with the same finger prints for like $5 million ...(FYI identical twins do not have same fingerprints)...pets on the otehr hand is almost a good idea... id LOVE to clone my cat!
