Why is biodiversity reduction bad

Loss of biodiversity: causes and consequences 

According to a UN report published in 2019, around one million of an estimated eight million animal and plant species worldwide are threatened with extinction. Experts also speak of the sixth mass extinction in history. Earlier extinction events in the history of the earth, also known as faunal changes, extinguished between 60 and 95 percent of all species. It takes millions of years for ecosystems to recover from such events.

Why is biodiversity important?


Healthy ecosystems provide vital services that we take for granted. Plants convert the sun's energy and make it available for other forms of life. Organic substances are broken down into nutrients by bacteria and other living things and provide plants with healthy soil to grow. Pollinators, on the other hand, are essential for the reproduction of plants and secure our food production. Forests and oceans are carbon sinks. The water cycle is heavily dependent on living organisms.


Good air, clean water and quality soils depend on the biological diversity of our earth. Biodiversity helps us fight climate change and reduces the effects of natural hazards.


Because living organisms interact in dynamic ecosystems, the disappearance of one species can have far-reaching effects on the food chain. It is impossible to know exactly what the consequences of mass extinction would be for humans, but we know that the diversity of nature is essential for us.
