This summer semester 2021 the Environmental Research Network (ERN) starts its new series of talks under the title “Transformative Change towards Sustainable Futures”. Bringing together environmental research experts from a variety of fields, it highlights the diversity of perspectives and know-how we need in order to make radical shifts towards more sustainable pathways. Contributions this semester include a psychological view on our plastic consumption, a political-science analysis of Fridays for Future, and an astrophysicist’s perspective on the impacts of light pollution. The talks address a broad audience of non-specialists, and will be accessible for students and the general public online. The ERN considers this format an important space for dialogue beyond disciplinary borders, about sustainability challenges that concern us all. Join us on a pathway that celebrates the diversity of contributions towards the transformative change required for sustainable futures for everyone!
