Biodiversity is also considered by many to have intrinsic value—that is, each species has a value and a right to exist, whether or not it is known to have value to humans csiro’s biodiversity book (morton & hill 2014) describes 5 core (and interacting) values that humans place on biodiversity. Biodiversity intrinsic value was acknowledged in 34 per cent of the lbaps analysed, but with relatively short narratives (on average only 19 sentences were used) most of these lbaps made a short reference to the intrinsic value of biodiversity without providing many details other biodiversity instrumental values, scientific and historical. Intrinsic value of biodiversity focus on inherent value of a species, not tied to any economic benefit difficult to prioritize conservation based on intrinsic values (in this world) instrumental value of biodiversity focus on the economic value a species can provide- value of lumber and crops.

A way of justifying the claim that nature as a whole has intrinsic value instrumental value in nature as a basis for the intrinsic value of nature as a whole robert elliot akin to intrinsic value1 the idea is that nature has systemic value, which is instrumental value in nature. When environmentalists talk about biodiversity, they will describe the importance of diversity in terms of the actual or possible instrumental value species have to humans and their wellbeing they resort to arguing for the intrinsic value of diversity. Biodiversity is not evenly distributed, rather it varies greatly across the globe as well as within regions among other factors, the diversity of all living things depends on temperature, precipitation, altitude, soils, geography and the presence of other speciesthe study of the spatial distribution of organisms, species and ecosystems, is the science of biogeography. Biodiversity has an intrinsic value that is worth protecting regardless of its value to humans this argument focuses on the conservation of all species, even if they are ecologically equivalent species.
Potential or option value : - so much of the world's biodiversity is yet to be studied in depth there is enormous potential in biodiversity to help us in various ways in the future there is enormous potential in biodiversity to help us in various ways in the future. 4 tourism supporting biodiversity untitled-1 4 18/06/15 10:06 am tourism supporting biodiversity 5 foreword traction and serves to heighten awareness of the intrinsic value of nature for us all many of the issues in the convention on biologi-cal diversity tend to affect the tourism sector, and progress made. Various attempts have been made to amalgamate the concepts of intrinsic value and ecosystem services, often with a stop-over at the economic concept of existence value.
Intrinsic value of biodiversity in this view, every species has a value and role in nature it has a right to exist, whether or not it is known to be useful to humans.

The value of biodiversity valor da biodiversidade alho, cjr thus, biodiversity has an intrinsic value because it is part of the natural world, and the conservation of species, genetic resources and ecosystems is important for the maintenance of natural ecological processes. Second, we end up ignoring the intrinsic value of species and ecosystems changing this misplaced emphasis on species richness will require significant reforms in all levels of our education systems. Extrinsic and intrinsic value systems share a common origin, such that extrinsic values are always derived from intrinsic value and life mutely expresses both intrinsic and extrinsic values—these are derived from and are products of biological evolution.
