"What a difficult time! Scientific facts do not count much anymore and are all too often replaced by „alternative facts“. So it is even more important that we as scientists reach out to the public, to decision makers in politics and industry and translate our findings into practical ways forward to halt the mass extinction of species and ecosystems, to combat climate change and to improve human welfare without deteriorating the environment." Prof. Manfred Niekisch, former Director of the Zoo Frankfurt, March 2020
