According
to the report of the World Biodiversity Council IPBES 2019 on the global state
of biodiversity, one million animal and plant species are acutely threatened
with extinction. In addition, the overexploitation of the last 50 years has led
to a massive decline in the performance of many ecosystems. One example of this
is the ecological services of flying foxes in Africa, which are affected by the
hunting of animals. Scientists at the Max Planck Institute for Ornithology in
Radolfzell have calculated the financial value of a colony of palm fruit bats
in Ghana for local people.
Animals
not only pollinate crops, they also contribute to the spread of plant seeds.
For example, flying foxes, which belong to the group of bats, eat fruit from
trees and swallow the seeds they contain. On their nocturnal flights from the
back to their sleeping tree, the animals excrete the seeds again.
Unfortunately, hundreds of thousands of animals are still killed
every year—with unforeseeable consequences for the biodiversity in African
forests.
