CNN 2 ：Thank you for joining us today，Dr.Caplan，and welcome.Dr：Glad to be here.
CNN：What are the ethical pros and cons of cloning？
Dr：The pros are that you might be able to help infertile individuals and couples have children，and by making cloned cells，you might find a way to make tissues and even organs to treat diseases.That's called therapeutic cloning.The cons are that human cloning is not safe.Animal cloning has produced dead，deformed and diseased animals.However，I do favor making cloned cells for research.P：What do you mean by“cloning human beings”？Just parts，or whole people？
Dr：What they are talking about in Washington，D.C.today is cloning people.The debate about stem cells that's been going on for many weeks is about making parts for people.
P：why are we even considering human cloning when animal cloning is as yet unperfected？
Dr：Good question.I don't think we should be.But，unfortunately，some scientists out on the fringe are threatening to ignore the miserable track record with animals，and start cloning people now.
P：In retrospect，wouldn't it have been better to approve cloning research with oversight and regulations？
Dr：I agree again.It's still not too late to do that.The House of Representatives3 here in the United States has banned all cloning.That's too strong in my view.I think we should allow some research with cloned cells，see if that works，keep it under government oversight，and that will be the best protection we can have against kooks and cults.
P：Airplanes weren't perfected when we attempted to launch humans in space.Can't be said here？
Dr：No.Babies are not astronauts.They can't consent.So you really have to be sure from your animal work that it's safe before you try cloning in people.
P：What happens to messed up human clones？How do we deal with them？
Dr：That's a question that the people who say they want to clone keep ignoring.
P：Which country is currently leading the way in clone research？
Dr：Undoubtedly，it would be the United Kingdom.Britain has passed a law allowing government money for cell cloning.Also，the country of Singapore has said that it will permit cloning research.Thirty countries，including England，have banned cloning for human reproduction.
P：Are you worried that human cloning will create a commercial market for human fetuses？
Dr：Not really.I think that if you make cells from adult DNA，as Dolly was made，then you don't really have market in embryos.If you want to make a human clone baby，however，you'll need a lot of money，since it would cost tens of thousands of dollars to try that.
P：Is there much resistance to organ-cloning？
Dr：Not really.As long as you're not making people，if you're really just making cells，or even skin or liver in a dish—while this seems odd—there really isn't any serious objection to that kind of work.
P：What do you think of the idea of creating a perfect type of human（blue eyes，blonde hair etc.）and cloning him repeatedly？
Dr：Well，the real future battle will not be about cloning，it will be about designing better babies.That's genetic engineering，not cloning.I think parents will want to make better and improved children.The key ethical question will be whether society will allow that，or whether it will be seen as too dangerous in terms of equity and fairness to create people who are simply too perfect，relative to others.CNN：Do you have any final thoughts to share with us？
Dr：I would not worry that we'll see a human clone any time soon.The science with animals shows that it's very hard to do.On the other hand，I think it would be a bad idea to panic and ban all research with cloning.We should prohibit cloning worldwide for making babies.I think we should keep the door open a little bit for basic research with cloning cells.
