OK, so it's a conservative website, so it's not too surprising she
doesn't even suggest any alternative artificial methods - or more
research for, say, a safer type of IUD. (Not to mention the non-
hormonal RISUG.)
However, animagirl (?), thankfully, pointed out that birth control
pills and RU-486 are hardly the only harmful chemicals coming out of
the sewage plants these days and into the water, so it hardly makes
sense to focus only on those.
I must say I'm glad I make a good deal of effort to avoid chemicals in
general.
