Biodiversity: is the amount and variety of organisms that live in a given area at a given time.

Measured 3 ways(1) Species Richness- Amount of different species(2) Eveness- Balance of the species(3) Genetic diversity- How closely the species are related

SPI 0807.5.4 (Biodiversity) Identify several reasons for the importance of maintaining the earth’s biodiversity.

Here are 8 Reasons to Maintain Biodiversity1) To feed the world2) To provide more medicine3) To maintain our economies4) To provide life support for our biosphere5) To avoid disrupting food webs6) To satisfy human curiosity7) To preserve nature's beauty8) To respect life in all its forms

1) To feed the world90 percent of the world's food comes from only 20 plant speciesExamples: Corn, Rice, Wheat, Soybeans, etc. If a disease or natural disaster damages or wipes out one or more of these crops, famine would result (millions could starve). With more varieties of these types of plants, we increase our chances of avoiding and/or reducing the impact of a famine.

2) To provide more and better medicine40% of medicine prescribed in the USA comes from plants, animals, or microorganisms.With less biodiversity there is less opportunity to find new medicines

4) To provide life support for our biosphereVarious plants and animals provide vital services to life on earthExample: Oysters filter water making it cleaner for other marine lifeExample: Forests absorb carbon dioxide and release oxygen

5) To avoid disrupting food websWhen we over-hunt or over-harvest wild plants and wild animals and/or wipe out species due to pollution and habitat destruction, we seriously disrupt the food chains and food webs
