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

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

Notes

SPI 0807.5.4BiodiversityNotes

1) To feed the world90 percent of the world's food come from only 20 plant speciesExamples: Corn, Wheat, Rice, 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 disaster

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

3) To maintain our economiesVarious plants and animals are vitally important parts of our national and global economiesIf some disaster were to wipe out one or more of these resources, tremendous financial hardship would result

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: Forest 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

6) To satisfy human curiosityHuman beings naturally are curious about our world and life in general. People enjoy learning about wildlife (both plants & animals)

7) To preserve nature's beautyBeautiful places with high biodiversity like Yellowstone park, the Smoky Mountains, and the Amazon Rainforest are popular places to visit
