To clone or not to clone?
Discussion
Are you for cloning or against cloning Do you think it is a good thing or a bad thing
for cloning beneficial to
organs used for transplanting(器官移植)
animals and plants that are becoming extinct agriculture(农业)
against cloning nature cloned animals an unexpected variation of genes(基因突变) law and morals (法律与道德) ethical (伦理的)
Conclusion
Cloning is a two-edge sword.
