The international, renowned, award-winning Canadian media ecologist Eric McLuhan died on May 18, 2018 unfortunately. Perhaps because his famous father Marshall McLuhan, Eric didn't get proper academic respect. In fact, Eric made original contributions in media ecology. His work deserves special research. On the occasion of the frst anniversary of Eric's death, this article reviews his achievement of media ecology studies. This article believes that Eric's main achievement includes: analyzing issues that should be paid attention to in the future; combining media study of Aristotle's formal cause that would lead to the end of the “straw man argument” of technological determinism; and participating in MEA's affairs actively and calling on media ecologists to act immediately.
