In arguing against the ethical nature of stem cell research, additional funding may lead to curing diseases, but may ultimately help less people due to limitations in supply, since embryos must be cultivated from women. For instance, it is relatively easy for companies to adjust for the demand of health care equipment or products, such as x-ray machines. These machines are used to ultimately reduce peoples‘ medical problems by pinpointing the causes. So if the demand for this equipment rises, then suppliers manufacture more equipment; however, in a situation where blastocysts…can be used to cure or alleviate certain kinds of deadly or debilitating disease, can private industry be trusted to make enough?. While research money and human efforts could aim towards advancement of these procedures, other medical technology research that may not involve controversy could loose ground. For example, procedures used to cure cancer patients are not ethically controversial, unlike stem cell procedures. We believe research money and efforts should not shift away from medical technologies used to treat major diseases such as cancer. In discussing the supply and demand of such medical technology, embryonic stem cell procedures should not take place for these reasons.
