George Marshall is an expert in “green communication”. For the past 30 years, he’s committed to ecology and especially in the preservation of forests and the fight against climate change (he worked with Greenpeace). George Marshall co-founded Climate Outreach in 2003, an NGO dedicated to strengthen public engagement for the environment. He will come and talk about this crucial fight, his truth but also about the psychological barriers we all face. He analyzed them in his compelling book Don’t Even Think About It: Why Our Brains Are Wired to Ignore Climate Change (2014).
