"I have been racking my brain, but still cannot come up with any traditional ... folk songs highlighting the decline and environmental threats to our native honeybee and bumblebees".

a good point well made. this is exactly the sort of thing that leaves me scratching my head over the proposals here. I wonder if the adjudicators queried this, that, by default there literally cannot be any trad songs on this topic, because the topic itself did not exist in any era one would associate with the "traditional".

If you wanted to be generous to the proposal, I suppose you could broaden the remit to include, say, traditional folk songs celebrating the outdoors and cycle of nature; and folk songs from the industrial age that bemoaned the encroachment of man onto nature. "Woodman, Spare That Tree", or the ecologically minded songs of Ewan MacColl, Peggy (and Pete) Seeger ... that sort of thing... Personally I wouldn't have the chutzpah to put in a proposal like that, I would feel like I was being a right chancer.
