Politics (from Greek: πολιτικά, translit. Politiká, meaning "affairs of the cities") is the process of making decisions that apply to members of a group.
I can't help feeling wary when I hear anything said about the masses. First you take their faces from 'em by calling 'em the masses and then you accuse 'em of not having any faces.
J. B. Priestley in Saturn Over the Water (1961) ch. 2.

A better understanding of the ecological mechanisms that take place within tropical coral reefs will help to ensure their conservation.
