I also heard the prog on radio 4, and she talked an awful lot of sense. They offer to reverse the op later on if the person wished to change their mind, but they have not had one take up the offer. On the face of it it is bordering on right wing eugenics, but when you heard this passionate & very caring person talk about the affects of drug addiction on unborn & totally unwanted babies, and how these children suffer terribly when born and have to be weaned off the drugs it was heartbreaking. and if all that didn't make you think again, they had done a study and 'costed' how much it took to look after one of these children from birth right through until he died of neglect at the age of 3 – $4m! I know we should not put a price on life, but c'mon someone has to say it!A very difficult subject, but one that needs to be discussed
