DIRECT VALUE
_____________________________________
Biological resources, therefore , are valuable. There are direct and indirect values of these resources. The direct values include the consumptive use and productive use values. The consumptive use value is the value placed on nature’s products that are consumed directly, without passing through a market. When direct consumption involves recreation, as in sport fishing and game viewing, the consumptive use value is the whole recreational experience. The productive use value, on the other hand, refers to products which are commercially harvested or used. Productive use of resources such as timber, fish, medicinal plants, honey, construction materials, mushrooms, fruits and so forth have a major impact on the national economy.

INDIRECT VALUE
_____________________________________
Indirect values, which deal primarily with the functions of ecosystems , are not normally reflected in national economic systems but they far outweigh direct values. These values tend to reflect the value of biological diversity to society at large rather than to individuals or corporate entities. Direct values often derive from indirect values, because plants and animals are supported by the services provided by their environments. Species without consumptive or productive use may play a very important role in the ecosystem, supporting species that are valued for their consumptive and productive use. For example high densities of birds in a certain area may limit the abundance of pests which would otherwise destroy crops; the birds themselves require a natural forest for nesting. The indirect values include non-consumptive use value, option value and existence value. The non-consumptive use value are those which deal with nature’s functions and services. These include photosynthetic fixation of solar energy and thereby providing the support system for other species, maintaining water cycles, regulating climate, production and protection of soil, absorption and breakdown of pollutants, recreational, easthetic, socio-cultural , scientific, educational, spiritual , and historical values of natural environments. The recreational value is very significant in tourism. People from all parts of the world want to experience a different and variety of animals and plants and therefore for the tourism sector to improve it is necessary that our biological diversity is maintained or improved.
