biological diversity

or

biodiversity,

the number of species in a given habitat. Scientists have variously estimated that there are from 3 to 30 million extant species, of which 2.5 million have been classified, including 900,000 insects, 41,000 vertebrates, and 250,000 plants; the remainder are invertebrates, fungi, algae, and microorganisms. Although other species remain to be discovered, many are becoming extinct through deforestation, pollution, human settlement and activities, and climate change. Much of this diversity is found in the world's tropical areas, particularly in the forestforest,
a dense growth of trees, together with other plants, covering a large area of land. The science concerned with the study, preservation, and management of forests is forestry.

 regions. A habitat in equilibrium has a balance between the number of species present and its resources. Diversity is affected by resources, productivity, and climate. The more pristine and extensive a diverse habitat, the better chance it has to survive a change or threat—either natural or human—because that change can be balanced by an adjustment elsewhere in the community; damaged or limited habitats may be destroyed by breaking the food chain with removal of a single species. Thus, biological diversity helps prevent extinction of species and helps preserve the balance of nature.

The Nagoya Protocol on Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization to the Convention on Biological Diversity is an international agreement which aims at sharing the benefits arising from the utilization of genetic resources in a fair and equitable way, including by appropriate access to genetic resources and by appropriate transfer of relevant technologies, taking into account all rights over those resources and to technologies, and by appropriate funding, thereby contributing to the conservation of biological diversity and the sustainable use of its components.
The Convention on Biological Diversity was an attempt to find an international strategy for conservation that would both recognize the sovereignity of states and the nature of biological diversity, which does not recognize state boundaries and operates as our common heritage (threats to it threaten people everywhere and benefits from it may benefit anyone).
