Badger culling
There’s a short news article in The Vegan (Summer 2010 issue) that mentions badger culling being unlikely to halt the spread of tuberculosis in British cattle herds.
It also mentions that culling costs would come to 2-3 times more than it saves the farmers.
The suggestion is that the Welsh Assembly should seriously consider using a badger vaccine (as previously used in England in 2010). Fortunately, badger culling has been suspended in England since 2008. However, the Welsh government is still considering doing it again.
