Several months ago the umbrella environment group Scottish Environment Link put up on its website a 10 point referendum challenge.  The 'Better Together' responses to the 10 challenges have just been added and the responses from the 'Yes' campaign are promised for 23 September 2013.  To date there has been very little discussion of the environment and the future governance of Scotland's environment save in the context of energy.   Hopefully, the challenge and now these responses will encourage more discussion.
