The decline in biodiversity has reached an unprecedented peak over the past 50 years. According to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), up to one million species are now threatened with extinction. Many of these could be lost forever within the next few decades. The speed at which this loss is progressing is alarming. The impact this could have on us humans, our well-being and our prosperity has so far received comparatively little attention in the public debate.
This is surprising when you consider that without short-term countermeasures, our natural resources could be lost at a rapid pace. And this has long-term consequences for almost all areas of life - from food, water availability and global warming to air quality and our economy. Specifically, according to UN figures, the loss of biodiversity threatens around half of global economic output. Expressed in figures, this amounts to an estimated 44 trillion US dollars per year.
What healthy ecosystems do for us
The World Economic Forum has even labelled the decline in biodiversity as one of the five greatest risks to the global economy. One reason for this is the so-called ecosystem services, i.e. the services we receive from nature. This "free" contribution from nature includes the following aspects, among others:
- Natural pollination
Pollination by insects is essential for the production of many fruits.
- Clean water
Natural filtering of precipitation through forests and wetlands provides us with clean drinking and irrigation water.
- Renewable raw materials
Forests and other ecosystems provide us with natural, sustainable and healthy building materials and raw materials.
- Fresh fish for consumption
Intact bodies of water support the natural reproduction of fish populations as an important source of food.
- Functional climate regulation
Forests and moors bind greenhouse gases and thus help to reduce CO² emissions.
