Economics of biodiversity
Encyclopedia
There have been a number of economic arguments advanced regarding evaluation of the benefits of biodiversity
Biodiversity
Biodiversity is the degree of variation of life forms within a given ecosystem, biome, or an entire planet. Biodiversity is a measure of the health of ecosystems. Biodiversity is in part a function of climate. In terrestrial habitats, tropical regions are typically rich whereas polar regions...

 but economists have also debated whether biodiversity is inherently valuable, independent of benefits to human.

s of information but the human species also has many variations. There are many millions of species of life on the planet each with valuable information. Many chemical formulae and forty-five percent of all drugs have bio-origin . In the long run keeping genetic records of all species could, however, be just as useful in this regard.

Some of the important economic commodities that biodiversity supplies to humankind are:

Food

Biodiversity provides high variety of food: crops
Crop (agriculture)
A crop is a non-animal species or variety that is grown to be harvested as food, livestock fodder, fuel or for any other economic purpose. Major world crops include maize , wheat, rice, soybeans, hay, potatoes and cotton. While the term "crop" most commonly refers to plants, it can also include...

, livestock

 are important food source of human species.
However, the number of species have been domesticated and cultivated are small if comparing with the number of species existing.
Wild species and varieties can supply genes for improving domesticated species by improving their yield, disease resistance, tolerance and vigor; this can increase the profit of farming.

Biological pest control

However, even with extensive research into the control species, their use is a risky business, as in the importation of the Cane Toad
