Final answer:
The use of ES cells for therapeutic cloning in humans raises ethical concerns regarding the destruction of human embryos, the commercialization of ES cells, and the impact on biodiversity.
Step-by-step explanation:
The use of ES cells for therapeutic cloning in humans raises several ethical issues. One major concern is the destruction of human embryos during the process of obtaining ES cells. This raises questions about the sanctity of human life and the moral status of embryos. Another ethical issue is the potential for exploitation and commercialization of ES cells. There is a risk that the use of ES cells may lead to financial incentives and the creation of a market for human embryos or ES cells, which raises concerns about the commodification of human life. Additionally, there are concerns about the long-term effects of therapeutic cloning on biodiversity and the potential for unintended consequences.
