Verdoyons! 2023
Contenu sous forme de paragraphes

Committed to fighting climate change and preserving biodiversity, Rennes 2 University supports numerous projects to raise awareness of environmental issues and encourage eco-responsibility. The Verdoyons! cycle, organized every two years, provides eclectic and thought-provoking information to our community. 

For one month, numerous events are scheduled on the Rennes campus (with many of them being free and open to all): workshops, meetings, screenings, exhibitions...

This year, the festival focuses on the crucial issue of green algae, as preventing its proliferation has become a real challenge for the Breton ecosystem. Artists and journalists alike have turned their attention to the subject. For Verdoyons!, their views will intermingle through an exhibition of photographs, a cine-concert and a film screening.
