Clone to our advantage
On medicine has the advantage,although there are a lot of disadvantages clone but it can also make many infertile men completed dream
Now the cloning scientific divided into therapeutic cloning sexual and reproductive cloning two kinds.The former is the use of embryonic stem cells cloned human organs,for medical research,to solve the organ transplant donor shortage problem,this is the international scientific community and ethical within both support,but there is a premise,is used for therapeutic cloning embryos cannot exceed 14 days of pregnancy the boundaries.For reproductive cloning sex,what say normally namely clone,due to its overall violated the life of ethical principles,so,scientists mainstream consensus is firmly opposed.UNESCO,the world health organization and the international human genome ethics committees and governments are also very clear that oppose reproductive sex cloning
Modern science and technology is a double-edged sword,in its benefit mankind can also bring some negative effects.This is kindled against us raises a question:modern technology,especially the modern life science and technology,don't respect ethical principle,will not listen to the voice of ethics?Professor shen pointed out:now some scientists propose,as long as science might do,you should do it.In fact,this is mistaken.If technology,we can produce a kind of serious harm to humans super life,difficult way can also go to manufacture?Some scientific lunatic is under the banner of "scientific freedom",to do some harm to humans.Therefore,we should guard modern science and technology by some ax-grinders utilization.In addition,nor make scientific freedom and ethical contradiction.The modern life science development suggests,ethical standard and guide,and no beam,listen to the voice of ethics,conducive to scientific more healthy,smooth development
1.会使地球人数增多
2.在医学上有好处,克隆人虽然有很多坏处但它也可以使许多没有生育能力的人完成梦想
3.现在科学界把克隆分为治疗性克隆和生殖性克隆两种.前者是利用胚胎干细胞克隆人体器官,供医学研究、解决器官移植供体不足问题,这是国际科学界和伦理学界都支持的,但有一个前提,就是用于治疗性克隆的胚胎不能超出妊娠14天这一界限.而对于生殖性克隆,即通常所说的克隆人,由于它在总体上违背了生命伦理原则,所以,科学家的主流意见是坚决反对的.联合国教科文组织、世界卫生组织和国际人类基因组伦理委员会和各国政府也都非常明确地表示,反对生殖性克隆
4.现代科学技术是一把双刃剑,在其造福人类的同时也会带来一些负面效应.这就向我们提出了一个问题:现代科技,特别是现代生命科技,要不要尊重伦理学原则,要不要倾听伦理的声音?沈教授指出:现在有些科学家提出,只要科学上有可能做到的,就应该去做.事实上,这是错误的观点.如果技术上我们能制造出一种严重危害人类的超级生命,难道也可以去制造吗?一些科学狂人正是打着“科学自由”的旗号,去做一些危害人类的事.因此,我们要警惕现代科学技术被一些别有用心的人利用.另外,也不能把科学自由和伦理道德对立起来.现代生命科学发展的事实表明,伦理的规范和引导,并没有束,倾听伦理的声音,有利于科学更健康、顺利地发展
