Explain ‘consumptive use values’ and ‘productive use values’ of biodiversity giving suitable examples.

Biodiversity value may be classified as follows:

1. Consumptive use Value:

These are direct use values where the biodiversity products can be harvested and consumed directly e.g. fuel, food, drugs, fibre etc.

(a) Food:

A large number of wild plants are consumed by human beings as food. About 80,000 edible plant species have been reported from the wild. About 90% of present-day food crops have been domesticated from wild tropical plants.

(b) Drugs and medicines:

About 75% of the world’s population depends upon plants or plant extracts for medicines. The wonder drug Penicillin used as an antibiotic is derived from a fungus called Penicillium. Likewise, we get Tetracycline from a bacterium. Quinine, the cure for malaria is obtained from the bark of Cinchona tree, while Digitalin is obtained from foxglove (Digitalis) which is an effective cure for heart ailments.

Recently Vinblastine and Vincristine, two anticancer drugs, have been obtained from Periwinkle (Catharanthus) plant, which possesses anticancer alkaloids. A large number of marine animals are supposed to possess anti-cancer properties which are yet to be explored systematically.

(c) Fuel:

Our forests have been used since ages for fuel wood. The fossil fuels like coal, petroleum and natural gas are also products of fossilized biodiversity. Firewood collected by individuals is not normally marketed, _____ ______ _______ ____ _____ _____ __________.
