Biological diversity – or Biodiversity means :

SDABC2015.png The ABC for Sustainable Cities - A glossary for policy makers. 1st edition (2015)

The variety of life on Earth. It is the variety within and between all species of plants, animals and microorganisms and the ecosystems within which they live and interact. Biodiversity comprises all the millions of different species that live on our planet, as well as the genetic differences within species. It also refers to the multitude of different ecosystems in which species form unique communities, interacting with one another and the air, water and soil. Biodiversity is explored at three levels: genetic diversity, species diversity and ecosystem diversity. It includes diversity in abundance, distribution and behaviour. Biodiversity also incorporates human cultural diversity, which can both be affected by the same drivers as biodiversity, and itself has impacts on the diversity of genes, other species and ecosystems.
