The truth about cloning cats and dogs When I first read about the controversial topic of pet cloning, I was shocked by the topic that was published on the Internet. Such services would have consumers who believe that to clone their pet is to extend time with a beloved friend. These merchants mislead pet lovers. Also important to consider is the influence of environment and experience on personality. Thus, it is not sure that pet cloning will result in an animal that has the same appearance or personality as the original animal. “Clone your pet” companies claim that the cloning process increases scientific knowledge of animal. What they fail to mention is the research involved in pet cloning. It is done purely to further the purpose of reproduction through the cloning process, and not to find cures to diseases and genetic abnormalities(畸形). It does not benefit animals or humans. In fact, as pet cloning is done for only commercial purposes, it exploits(利用 ) animals. ①Research_involved_in_pet_cloning_is_not_publicly_regulated,_so_it_is_unknown_whether_advances_made_are_beneficial_to_any_scientific,_non?commercial_community.
