Fewer weeds with Roundup tolerant soya? Fewer weed seeds for birds with
specific seed needs? Fewer insects with specific weed habitat needs that
birds then feed on? I don't know, my expertise is forests, but perhaps
others can tell me. However, I think all those who study UK birds will
say that the _general_ intensification of agriculture in UK since 1945
has generally been 'a bad thing for birds'. GM crops are a new level of
intensification, and the outcome on wildlife is, as yet, unknown. Nobody
forsaw that early insecicides were going to damage bird populations. And
in the UK, no one forsaw that feeding protine from rendered sheep would
lead to BSE, infecting cattle and ultimately humans. Personally, I don't
think GM _will_ harm birds, but I may well be wrong.

I don't think so. There is actually a lot of countryside left in UK, but
the nature of it has changed.
