Reducing animal product consumptioncan help to mitigate climate change and other environmental issues. Igor Asanov, Stephan Bruns and co-autors tested and compared the effectiveness of an individual and a social app-based 30-day challenge in reducing animal product consumption and found that both conditions reduced animal product consumption, with a lasting effect only for the social treatment (encouragement to involve family and friends) 3 months after the intervention.
