Opponents of embryonic stem cell research, which often uses embryos discarded by fertility clinics, want it to be severely restricted or banned outright as inhumane.
Don't these embryos get burnt and put the dump anyway? This might be in bad taste, but it's better to recycle these than to just junk it.
As Congress considered legislation to allow broader use of embryonic stem cells, members were swamped with calls from people suffering from diseases for which stem cells research might be the only hope, and from equally vehement opponents. In 2006, the Republican-controlled Congress passed a bill to expand research. In response, Mr. Bush issued the first veto of his presidency. In 2007, Congress, now in Democratic hands, passed a similar bill by a larger margin, but still not by enough to override the veto that Mr. Bush announced on June 20
If it helps save lives then I think it should be done. It's about balancing out the positive and the negative aspects of it. Dead embryos are already dead, but dying patients can at least have some chances of living.
