Glacier stripped pipe of industrial pollution (4,4)
I believe the answer is:
acid rain
'industrial pollution' is the definition.
'acid rain' can be an answer for 'pollution' (acid rain is a kind of pollution). I'm not sure about the 'industrial' bit.
'glacier stripped pipe' is the wordplay.
'stripped' indicates the central letters.
'pipe' becomes 'drain' (drain is a kind of pipe).
The centre of 'glacier' is 'aci'.
'aci'+'drain'='ACID-RAIN'
'of' acts as a link.
Can you help me to learn more?
(Other definitions for acid rain that I've seen before include "Polluted water" , "Pollution from the sky" , "it's bad for the environment" , "environmental problem" , "Destructive precipitation" .)
