Hello Kent Marshman
What a terrible story. It is sad that you seem to be the only one that cares

. You need an outcry from people in the local area about what is happening to the swans. I would not be afraid of pulling at heart strings by sending photos to the papers.
I suggest you tell the papers that this carnage is continuing in the full knowledge of the organisations that should be protecting these animals (by the way have you tried the RSPCA?). Natural England do have the power to initiate this sort of discussion and encourage the energy company to look at how they can prevent these atrocious strikes.
A petition may be another idea.
