Lloyd - thanks for the counterblast! I'm now better informed. I've been involved to the small extent that: (1) my uncle was burnt out of his Queensland home some years ago by forest fires and (2) I've been living in South Wales for some 40 years, fortunately without any pressing need to emigrate elsewhere like your ancestors; also, I suppose, (3) I'm a retired university lecturer specialising in environmental problems arising from human activity (marine oil pollution and coastal development, before your agricultural hackles start rising!)
