Because opponents of stem cell research say it is immoral. Opponents are typically religious and believe life starts from conception and say taking embryonic stem cells is murder. Not all stem cells have to come from embryos though.
embryonic stem cells can differentiate into more types of cells
One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become. Embryonic stem cell can become all cell types of the body because they are pluripotent. Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin.

The primary reason and most important reason is that some people are scientifically illiterate. They don't understand the science behind the research and they do not have even the basic education to begin to understand it. They don't even try to understand it and they let others try to explain it to them but those people often have some sort of agenda. Science itself is not good or bad, it is what is done with it. If all of society doesn't what to use this knowledge, a least we all have made the decision not just a handful. There are two methods of stem cell research. 1. Embryonic stem cell and 2. Adult stem cell. There is not somuch opposition of manipulating the stem cells from adult cells. On the other hand, Embryonic stem cell research involves the value of life. Thus the main issue for embryonic stem cell research is whether potential embryonic life should be treated with honor and human dignity. Which itself is only a religious viewpoint and not science fact.
Researchers could use embryonic stem cells to find the cure to many different disorders and illnesses.

There are people for and against using embryonic stem cells. People against embryonic stem cell use feel that an embryo is a person and can not be used for science. People for embryonic stem cell use feel that the embryo does not qualify as a human as it doesn't get past a basic division of cells, and it would be better to use it for science than discard from a fertility clinic, etc. Science is currently working on a way to bypass embryonic cell use in order to find the cure without the controversy.

Human embryonic and adult stem cells each have advantages and disadvantages regarding potential use for cell-based regenerative therapies. ... Adult stem cells are thought to be limited to differentiating into different cell types of their tissue of origin. Embryonic stem cells can be grown relatively easily in culture.

Stem cells themselves are not controversial. There are different types of stem cells. Hematopoietic stem cells are the building blocks of blood. They are found in bone marrow and umbilical cord blood. They are currently used successfully to treat a number of different diseases. These are not controversial at all. Embryonic stem cells are controversial because they are obtained from embryos. Some people believe that using embryos to produce stem cells is unethical. The 'embryos' the anti-stem cell voice talk about contain about 75 - 200 cells, and are known as blastocytes. The cells are undifferentiated, meaning they as yet have no purpose. The Pro-Life movement refer to this collection of cells as a human being about 2-4 days after fertilization. Blastocytes are the best source of undifferentiated stem cells, and those used would be the excess discarded after IVF. They would generally be destroyed - why not use them to save human life? For Pro-Life- destroy these 'embryos' or use them to save life? Please explain your stance!
