Biodiversity
Biological diversity, or biodiversity, means the diversity of life on Earth – the variability among living organisms and the ecological complexes of which they are part.
Three levels of biodiversity are distinguished:
- The diversity of ecosystems and ecological communities, habitats and landscapes
- Diversity between species
- Genetic variety within species
The main international agreement on biodiversity conservation is the 
Convention on Biological Diversity, CBD.
The German National Biodiversity Strategy was adopted by cabinet resolution of 7 November 2007.
