Butterfly Effect: How One Species Saves Another
However, the extinction of species is only the tip of the iceberg, as Johannes Rüdisser knows: “Before a species becomes extinct, a lot happens beforehand. We can also see that species that are not immediately endangered are declining massively.” This can throw our ecosystem into an extreme imbalance. The easiest way to explain this is with the example of pollinating insects: “Here it is not only important which rare species is doing it, it is above all that there are enough individuals that can pollinate fruit trees, for example.” There is no such thing as a reduction in insect populations fewer pollinators for food production, the animals are also missing as food for other animal species such as birds, amphibians or bats.
If the biological diversity is high, this is a reassurance against climate change and other changes in the habitat: If there are many individuals and groups of an animal species, some of them may be able to specialize better than others in certain conditions, which ensures the progress of the species. Biodiversity is the umbrella term that includes both within the variety of species and the variety of individual art.
