Change Makers
featuring Lefteris Arapakis, co-founder of Enaleia

Directed by Professor Casey Beck, Program Director of Digital Media Practices, Tulane University

About the documentary:

Change Makers, featuring Lefteris Arapakis of Enaleia, is a standalone documentary short that also serves as a pilot episode for a potential series exploring the power of individuals to make a difference in the fight against the climate crisis.

Lefteris, along with his best friend, founded Enaleia—initially conceived as a fishing school to address unemployment in Greece and to help prepare the industry for the retirement of older fishermen by training a new generation.

However, during this process, they uncovered another urgent issue: plastic pollution in the sea. Fishermen were routinely separating plastic from their catch—only to throw it back into the water. Lefteris decided to involve the fishing community in tackling this larger environmental threat—one that directly endangered their livelihoods.

This compelling film brings to light the urgent need for ocean conservation and the inspiring work being done to protect marine life and coastal communities.
