The relative abundance of species in an assemblage is the only factor that determines its importance in a diversity measure. Terrestrial biodiversity is usually greater near the equator, which is the result of the warm climate and high primary productivity. But I think that genetic engineering is going to soon be more than just tinkering with genes but designing whole new organisms. What's the best way to measure biodiversity? It may or may not reflect a pleasant planet to live on, but will it be the case ? OK, well that is not happening now, and if it ever did, it would need to be under tight regulatory control. As I understand it there are various ways biodiversity is measured, with varying results. Review data policies. All species are equal:this means that richness measurement makes no distinctions amongst species and threat the species that are exceptionally abundant in the same way as those that are extremely rare species. Biodiversity loss, also called loss of biodiversity, a decrease in biodiversity within a species, an ecosystem, a given geographic area, or Earth as a whole. Biodiversity is not just the number of species, but also the phylogenetic range of diversity. If that is the question, then ask that. - Definition, Types & Stages, Concept of 'Species': Definitions & Limitations, What is the Biogeochemical Cycle?
