Value of biodiversity

Many important chemicals have their origin from the diverse flora and fauna, used in various industries. The role of biodiversity in providing ecosystem services is twofold. This is often referred to as the latitudinal gradient in species diversity.

We use those values in chapter 4 to discuss how they can contribute to decisions on management of biodiversity. Biodiversity and human health. In addition, such services in biophysical and economic terms characterize the institutional mechanisms needed to generate incentives for their preservation Daily Page 44 Share Cite Suggested Citation: The production of oxygen Value of biodiversity land based plants and marine algae; b.

In allopathy, the pharmaceutical industry is much more dependent on natural products. Productive Use Value 7. Indeed, microorganisms are already playing important roles, both in the prevention of pollution for example, through waste processing and environmental monitoring and in environmental restoration for example, through bioremediation of spilled oil.

They also provide opportunities for recreational activities such as hiking, canoeing, birdwatching and nature photography. Biodiversity has a fundamental value to humans because we are so dependent on it for our cultural, economic, and environmental well-being. Similarly, the flood control service that is lost when landowners fill their wetlands might have little direct effect on those landowners, but the private economic benefits of land conversion to agriculture will be important see the following case study on the Everglades.

For example, vegetation cover protects the soil from erosion by binding soil particles and minimizing the effects of water runoff. Since the indigenous people always protect the forests for their own benefit.

US man and the biosphere human-dominated systems directorate workshops on ecological and societal issues for sustainability. Biodiversity in Wild Systems Humans still harvest considerable quantities of food, fuel, and fiber from nondomesticated ecosystems. Both points of view intrinsic and anthropocentric need not be contradictory, as they serve the same ultimate purpose.

Nonnative and nuisance species, such as Melaleuca quinquinervia a tree introduced from Australia in the early s to help drain the Everglades and the Brazilian pepper tree Schinus terebinthifoliushave invaded extensive areas, outcompeting native plants. The conversion of a park to a parking lot will obviously change patterns of water runoff, but other effects of habitat conversions are difficult to predict.

Moreover, there would be a Evaluating the trade-offs of alternative management strategies requires quantitative estimates of the costs and benefits of their outcomes, including the value of biodiversity lost or preserved.

The relative success of the program is attributable largely to deliberate efforts to integrate public opinion and participation into the decision-making process. It follows that the species present today have unique histories. It is obtained from bacterium.

Food, fuel and drugs. Of a total of People are motivated by more than the satisfaction of their physical needs; they are moved by the possibility of expanding their horizons—both their own experience and also knowledge "for its own sake".

While records of life in the sea shows a logistic pattern of growth, life on land insects, plants and tetrapods shows an exponential rise in diversity. Each species is likely to be affected differently by a given change in climate, so the risk that all species involved in a particular service will be lost from a system is lessened.

The history of biodiversity during the Phanerozoic the last million yearsstarts with rapid growth during the Cambrian explosion —a period during which nearly every phylum of multicellular organisms first appeared. Genetic diversity provides the raw material for plant breeding, which is responsible for much of the increases in productivity in modern agricultural systems.

The provision of native species and genes used in industry research and development, for instance, in traditional breeding and biotechnology applications in agriculture, forestry, horticulture, mariculture, pharmacy, chemicals production and bioremediation; f.

Salts that had accumulated deep in the soil salinized the soil surface. The maintenance of fresh water quality by vegetation slowing run off, trapping sediment and removing nutrients and by soil organisms breaking down pollutants; c.

The most fundamental value of biological resources particularly plants is providing food.

The value of biodiversity

The services include the provision of clean water, regulation of water flows, modification of local and regional climate and rainfall, maintenance of soil fertility, flood control, pest control, and the protection of coastal zones from storm damage.Some of the major values of biodiversity are as follows: 1.

Environmental Value 2. Social Value 3. Ecosystem Services 4. Economic Value 5. Consumptive use value 6. Productive Use Value 7.

Ethical and Moral Value 8. Aesthetic Value. Biodiversity is the most precious gift of nature mankind is blessed with. 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.

Biodiversity has proven to hold enormous value when adapted for use in health, agricultural, or industrial applications. In the field of medicine alone, approximately 50% of current prescription medicines are derived from or modeled on natural substances.

The direct values are of two types (i) Consumptive use value and (ii) Productive use value. Consumptive use value: These are the direct use values where the biodiversity products can be harvested and consumed directly. Biodiversity generally refers to the variety and variability of life on Earth.

According to the United Nations Environment Programme (UNEP), biodiversity typically measures variation at the. The value of biodiversity Ecosystems, interdependent webs of living organisms and natural resources, are essential to sustain all life on earth.

Throughout earth’s history, healthy ecosystems have usually been resilient enough to adapt to gradual environmental change.
