Environmentalist's prefix (3)

Ross

I believe the answer is:

eco

'environmentalist's prefix' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for eco that I've seen before include "Umberto --, Italian writer" , "Environmental group" , "Umberto - - , novelist" , "Green prefix" , "Umberto -, Italian author (The Name of the Rose)" .)

I've seen this clue in the USA Today.
