Guiding Away from Nature?

I must admit that, like a number of authors and poets, I am somewhat disturbed by the OUP Junior Dictionary editors' decision to reportedly cut words associated with the natural world (e.g. acorn, buttercup and conker) in favour of words like attachment, blog and celebrity (http://www.theguardian.com/books/2015/jan/13/oxford-junior-dictionary-replacement-natural-words). I appreciate that language changes (as does childhood) and that space has to be made for new terms and that the objectors might be criticised for having a rose-tinted view of their own childhoods but I do think that children need some understanding of nature and the challenges it faces (largely as a consequence of anthropogenic -they will find out what that word means soon enough- effects). This is especially true in a world where allegedly a substantial proportion of children think that milk is generated by a machine at the back of their local Tesco.
