Flutterby!

 I very much like butterflies but I have to wonder whether the decline of some species in Europe (blamed on the effects of changing agricultural practices leading to fewer flower-filled meadows) needs to be reversed by going back to older production techniques  (http://www.guardian.co.uk/environment/2010/dec/09/grassland-butterflies-decline-europe ).  Presumably, the now threatened species were not so common before meadows were created and extended by human activities. It would seem better to uncouple the link between agriculture and the encouragement of these attractive species (very clearly a 'human' choice).
