Biodiversity

Bio smorgasbord is the degree of variation of life forms within a effrontery species, ecosystem,biome, or an entire planet. Biodiversity is a measure of the health of ecosystems. Biodiversity is in part a function of climate. In terrestrial habitats,  tropic regions are typically rich whereas polar regions support fewer species.
Rapid environmental changes typically cause  green goddess extinctions. 1 estimate is that less than 1% of the species that have existed on  soil are extant.[1]
Since life began on Earth, five major mass extinctions and several minor events have take to large and explosive drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the Cambrian explosionâ€"a period during which the majority of multicellular phyla first appeared.[2] The next cd million years included repeated, massive biodiversity losses sort out as mass extinction events. In the Carboniferous,rainforest collapse led to a great loss of plant and animal life.[3] The PermianTriassic extinction event, 251 million years ago, was the worst; vertebrate retrieval took 30 million years.[4] The most recent, the CretaceousPaleogene extinction event, occurred 65 million years ago, and has often attracted more attention than others because it resulted in the extinction of the dinosaurs.

The period since the emergence of humans has displayed an ongoing biodiversity decrement and an accompanying loss of genetic diversity. Named the Holocene extinction, the reduction is caused primarily by human impacts, particularly habitat destruction. Conversely, biodiversity impacts human health in a number of ways, both positively and negatively.[6]
The United Nations designated 2011-2020 as the United Nations Decade on Biodiversity.

The terms biological diversity or biodiversity can have many interpretations. It is most commonly used to replace the more clearly defined and tenacious established terms, species diversity and species richness.
