'environmental problem' is the definition.
The definition suggests a singular noun which matches the answer.

'loonies in plot foolishly skirting universal' is the wordplay.
'foolishly' indicates an anagram.
'skirting' is an insertion indicator.
'universal' becomes 'U' (film certificate).
'loonies'+'in'+'plot'='looniesinplot'
'looniesinplot' is an anagram of 'noisepolltion'.
'noisepolltion' placed around 'u' is 'NOISE POLLUTION'.
