We've had various scientific studies on the above, very emotive subject. The government based DEFRA has commissioned most of them including the latest one, a very brief investigation, which suggests that another cull is justifiable. It will now go ahead in the very near future.
An earlier one, conducted over more than 9 years 1998 - 2006, published 2007, by the ISG (Independent Scientific Group) actually concluded that it would achieve virtually nothing to continue culling badgers because they are apparently only one possible 'culprit' among many.
***N.B.*** My second link contains the assertion that "..the latest evidence suggests that, nine years after culling, incidence might fall by 9-16%.."
What do you think, folks?
