    There is local biodiversity, which directly impacts daily life, affecting the availability of fresh water, food choices, and fuel sources for humans. Regional biodiversity includes habitats and ecosystems that synergizes and either overlaps or differs on a regional scale.

  4. Measurement of biodiversity - Wikipedia

    en.wikipedia.org/wiki/Measurement_of_biodiversity

    A variety of objective means exist to empirically measure biodiversity. Each measure relates to a particular use of the data, and is likely to be associated with the variety of genes. Biodiversity is commonly measured in terms of taxonomic richness of a geographic area over a time interval. In order to calculate biodiversity, species evenness ...

It is a variation in the ecosystems found in a region or the variation in ecosystems over the whole planet.

  8. Biodiversity loss - Wikipedia

    en.wikipedia.org/wiki/Biodiversity_loss

    Biodiversity loss happens when plant or animal species disappear completely from Earth or when there is a decrease or disappearance of species in a specific area. Biodiversity loss means that there is a reduction in biological diversity in a given area. The decrease can be temporary or permanent.
