Describe the consumptive use value of biodiversity as food, drugs and medicines, fuel and fibre with suitable examples.

Answers (1)

Consumptive Use Value: Many natural products are consumed at the local level by human beings. However, we neither sell nor buy these products. These products do not make a direct contribution to the nation’s economy. The value of these products is called the consumptive use value of biodiversity.

(a) We pay for almost all the food we consume, but we do not pay for the soil, water and air which play an important role in food production.

(b) Many naturally occurring herbs are used for their medicinal use by indigenous people. In most cases, people do not need to pay for using such plants. This also shows the consumptive use value.

(c) Almost 2.4 million people all over the world use firewood for cooking and heating. People who use firewood do not need to pay for that. Had they been using some other fuel; they would have paid some money for that. This shows the consumptive use-value of firewood.

(d) In rural areas, people often use naturally growing fibre plants for making ropes and other useful items. They do not pay for the fibre. This shows the consumptive use-value of fibre.
