Conservationists tell us about the extinction of wildlife, but there is another more insidious extinction going on right now – the disappearance of traditional dairy farmers, who have supplied our nation’s milk for generations. As each demoralised farmer quietly gives up and goes out of milk – and there are nearly two a day being forced out right now – a precious and irreplaceable part of our national heritage is lost forever. The Prince of Wales is absolutely right to be highlighting the plight of small family farms in general and dairy farms in particular.
