Care about some area (4)
I believe the answer is:
acre
'some area' is the definition.
(area of land)
'care about' is the wordplay.
'about' is an anagram indicator.
'care' with letters rearranged gives 'ACRE'.
(Other definitions for acre that I've seen before include "Israeli seaport" , "Care about the piece of land" , "marine location in Israel" , "Mediterranean port" , "Four roods - Israeli port" .)
