According to the Living Planet Report 2016 published by the World Wildlife Fund (WWF), biodiversity has never been in worse shape than today. The populations of vertebrate species monitored worldwide have on average declined by more than half in the last forty years. The main causes are loss and degradation of habitats, species overexploitation, pollution, invasive species and disease, and climate change that will, in the years to come, add yet more pressure on these populations to adapt. Changes in ecosystems and biodiversity are also studied by the Munich-based ecologist Prof. Dr. Wolfgang W. Weisser. As part of the lecture series “Science in the Dinosaur Hall” at the Berlin Natural History Museum, Professor Weisser, on November 11, at 7:30 p.m., will talk about “Why We Should Care about Biodiversity.”
