Animal conservationist starting national organisation against hunting … (4)
I believe the answer is:
noah
'animal conservationist' is the definition.
(I've seen this before)
'starting national organisation against hunting' is the wordplay.
'starting' suggests taking the first letters.
The first letters of 'national organisation against hunting' is 'NOAH'.
(Other definitions for noah that I've seen before include "Animal rescuer" , "First collector of animals?" , "Legendary Biblical boat-builder" , "He built an ark" , "Biblical patriarch" .)
