Why are more and more species becoming extinct? What can we learn from the species extinctions of the geological past? And how can we use the findings from paleontology and biology to slow down, or better still reverse, the species decline? These questions are addressed by a small online symposium to which Dachverband Geowissenschaften (DVGeo) and Verband Biologie, Biowissenschaften und Biomedizin in Deutschland (VBIO) invite decision-makers and interested parties (May 6, ’21: 3-5 p.m.)
