environmental +‎ -ist

   • 1926, Clark Wissler, 'The Relation of Nature to Man in Aboriginal America', 1971 edition, page 211-212:

If, for example, an unusual number of distinguished men are born and reared in the same locality, the environmentalists assert that the causes for their appearance were entirely external and that had their parents changed habitats with those residing elsewhere the result would have been the same, except that the family names of these eminent men would have been different.
