Genetics - Thinking about cloning

Cloning technology should be used to create clones to staff our armies.

I personally don't agree with this. If you really think about it these people won't be mindless they will still be real breathing people they will still feel and be just as aware of what is going on like us. Although they will never know anything different they will still know that they have been created in place of others. It wouldn't be nice to be born only to fight and die. it would be just the same as us being used for that purpose. These people that would be labelled as clones wouldn't be treated as humans. They would live with the knowledge that they have no family and are purely made to fight for people who genuinely don't care for them.

We should create clones to extract organs from them for people who need them to survive.

This would be morally wrong to create someone only to use them for organs. These people would need to be raised to be adults almost because the organs would need to be the correct fit for the patient because of this these people would only live a short life and would be expected to die at a certain age. this would not only be a horrible life but just imagine how brutal it would be to be created and raised only to be told that you have to die to save someone who you don't know or care for. 

We should use cloning technology to create highly productive plants and animals this could end world hunger 

This to me is a good idea. If we replicate these plants and animals then it could be used to save many people who live in the poorer areas of the world it would make it easier for people to find food and because of production being so easy the prices could drop making life easier for most people who don't have a lot of money.

Cloning technology should be used to replicate a child that is dying of a terminal illness.

I can't even begin to explain how bad of an idea this is. The child who is created may not even have the same personality as the deceased child. there is nothing saying that clones are identical in personality and voice. This would also stop the grieving process for the parents and family. after suffering such a great loss they should focus on recovery not creating a replica of their deceased child.

We should clone endangered animals and bring back to life animals who have become extinct.

This one is debatable because in one case they're just harmless animals but at the same time, these animals could cause harm to our environment although I see the point in cloning the endangered species but bringing animals that have become extinct is probably not the best idea. These animals have become extinct for a reason and they should stay that way.

We should bring back to life famous and influential people from the past.

These people being "brought back" wouldn't even be the same person they would have completely different lifestyles and personalities. Yes maybe if you brought back Einstein he would have a high intelligence but there is nothing saying he would still become a scientist. He could grow up in different circumstances. even if we did bring these people back they would have to start as a baby from square one. They wouldn't be automatic adults.
