Definition Of Global Biodiversity

And the genetic diversity among them.

Definition of global biodiversity. The ecosystems that house them. Biodiversity may be seen as an intricate web in which each part is interdependent. While earth s biodiversity is so rich that many species have yet to be discovered many species are being threatened with extinction due to human activities putting the earth s magnificent biodiversity at risk. Biodiversity describes the variety of life on earth.

Estimates on the number of earth s current species range from 2 million to 10 12 of which about 1 74 million have been databased thus far and over 80 percent have not yet been described. Threats to global biodiversity include natural extinction an event that occurs to species yearly as well as human actions such as pollution. The biodiversity of planet earth is the total variability of life forms forms. Global biodiversity information facility.

A common measure of this variety called species richness is the count of species in an area. Global biodiversity is the measure of biodiversity on planet earth and is defined as the total variability of life forms. Gbo 5 synthesizes scientific basis for urgent action. Towards a landmark new global post 2020 biodiversity framework.

Biodiversity encompasses the genetic variety within each species and the variety of ecosystems that species create. Currently about 1 6 million species are known but this is thought to be a serious underestimate of the total number of species. The fifth edition of global biodiversity outlook gbo 5 is a final report card on progress against the 20 global biodiversity targets agreed in 2010 with a 2020 deadline and offers lessons learned and best practices for getting on track. It encompasses the 8 million species on the planet from plants and animals to fungi and bacteria.

Global overview describing biodiversity as a key pillar of ecologically sustainable development providing a synthesis of the latest information on the state and trends of global biodiversity. Biodiversity refers to the variety of living species on earth including plants animals bacteria and fungi. Biodiversity the variety of life found in a place on earth or often the total variety of life on earth. More than 99 percent of all species that ever lived on earth are estimated to be extinct.

The increasing use of the term biodiversity is being driven by the fact that in an ecological context global biodiversity itself is being lost at an alarming rate 12 although it has been shown that the significant global biodiversity loss that has occurred over the timeframe of human existence has not stopped global human population increase 13 there is clear evidence that biodiversity loss.
