Biodiversity is the result of 3.5 billion years of evolution. [106] The origin of life has not been established by science, however, some evidence suggests that life may already have been well-established only a few hundred million years after the formation of the Earth .
The Convention on Biological Diversity (CBD), known informally as the Biodiversity Convention, is a multilateral treaty.The Convention has three main goals: the conservation of biological diversity (or biodiversity); the sustainable use of its components; and the fair and equitable sharing of benefits arising from genetic resources.
"The sustainable use of the components of biological diversity" [5] "The fair and equitable sharing of the benefits arising out of the utilization of genetic resources ” [ 5 ] The CBD currently follows the Strategic Plan for Biodiversity 2011-2020 and its Aichi Biodiversity Targets , [ 6 ] used as a vehicle to maintain synergies at National ...
Insects make up the vast majority of animal species. [14]Chapman, 2005 and 2009 [9] has attempted to compile perhaps the most comprehensive recent statistics on numbers of extant species, drawing on a range of published and unpublished sources, and has come up with a figure of approximately 1.9 million estimated described taxa, as against possibly a total of between 11 and 12 million ...
The concept of the natural environment can be distinguished as components: Complete ecological units that function as natural systems without massive civilized human intervention, including all vegetation, microorganisms , soil , rocks , plateaus, mountains, the atmosphere and natural phenomena that occur within their boundaries and their nature.
Ecosystem diversity addresses the combined characteristics of biotic properties which are living organisms (biodiversity) and abiotic properties such as nonliving things like water or soil (geodiversity). It is a variation in the ecosystems found in a region or the variation in ecosystems over the whole planet.
Communities can have a series of complex, direct and/or indirect, responses to major changes in biodiversity. [35] Food webs can include a wide array of variables, the three main variables ecologists look at regarding ecosystems include species richness, biomass of productivity and stability/resistant to change. [35]
In this sense, the biosphere is but one of four separate components of the geochemical model, the other three being geosphere, hydrosphere, and atmosphere. When these four component spheres are combined into one system, it is known as the ecosphere. This term was coined during the 1960s and encompasses both biological and physical components of ...
