Biodiversity is a term that is far from being firmly anchored in people’s minds. Global climate change can no longer be ignored as a fact, problem and danger, “Fridays for Future” is an expression of this situation. By contrast, the “Sixth Mass Extinction” is fully under way, yet many people are still unaware of the term biodiversity. This, and the fact that a trend reversal of global warming cannot take place without simultaneously stopping habitat destruction and loss of biodiversity, was addressed in Elisabeth Haring´s talk at the “Fridays For Future” strike on 15.11. on the Stock im Eisenplatz in Vienna.
