The term sounds academic and abstract, but it actually describes the web of life on our planet: For nearly two weeks, biodiversity will be the topic of the UN conference COP15 in Montreal. The threat to this web of life is as dangerous as the climate crisis – and closely related to it: Without a reasonably functioning nature, there is no hope for curbing global warming. And if greenhouse gas emissions do not decrease, biodiversity is beyond saving. It is that simple and that complicated.
