Stem Cells - parting with the embryo

Researchers have succeeded in generating new lines of human embryonic stem cells without destroying the embryo - full story

So , if you can start a stem cell line, but not kill the embryo, that should solve the problem, right?

Probably not, after all, those "environmentalists" who wanted us to stop burning coal, reduce nuclear, etc., and who touted renewable energy for years, now they think wind mills are bad.. (see for example)

Maybe stem cells plucked harmlessly from embryos will lead to global cooling?
