4. Biodiversity
Guided Notes 11

5. Value of Biodiversity Variety = Diversity
Biodiversity-the total of the genetically based variety of all organisms in the biosphere
Ecosystem Diversity-the variety of habitats, communities, and ecological processes in the living world

6. Value of Biodiversity Species Diversity-number of different species
1.5 million species currently exist
Genetic Diversity-total of all the different forms of genetic information carried by all organisms living on Earth

7. Value of Biodiversity
Biodiversity is one of Earth’s greatest natural resources. Species of many kinds have provided us with foods, industrial products, and medicines—including painkillers, antibiotics, heart drugs, antidepressants, and anticancer drugs

8. Value of Biodiversity
The biodiversity represented by wild plants and animals is a kind of “library” of genetic information upon which humans can draw for future use
When biodiversity is lost, potential sources of material with significant value to the biosphere and humankind may be lost with it.

9. Threats to Biodiversity
Human activity can reduce biodiversity by causing the following:
Habitat Destruction
2. Wildlife Products Demand
3. Pollution
4. Invasive species

10. Threats to Biodiversity
Extinction-when a species disappears from all or part of its range
Endangered species-a species whose population size places it in danger of extinction

12. Pollution Pesticide-a chemical used to kill insects
DDT-harmful pesticide banned in the 1970s after causing major harm to bald eagles and other large birds
However, DDT helps stop insect-borne diseases such as malaria.

13. Biological magnification-concentrations of a harmful substance increase in organisms at higher trophic levels in a food chain or food web
Therefore the pollution gets worse at each level as you go up.

14. Pollution

15. Silent Spring is a book written by Rachel Carson in 1962.
The book condemned the use of DDT as a pesticide. Carson claimed that DDT was causing birds to produce eggs with thin shells that caused a lot of deaths.

16. Silent Spring was a very controversial book and started a lot of discussion that led to the banning of DDT.
The book is also credited with starting the environmental movement of the 1970s that tried to prevent actions that harmed the environment.

17. Conservation
Conservation-the wise management of natural resources including the preservation of habitats and wildlife
Many efforts are aimed
at managing individual
species to keep them
from becoming extinct

18. Conservation
Today, conservation efforts focus on protecting entire ecosystems as well as single species. Protecting an ecosystem will ensure that the natural habitats and the interactions of many different species are preserved at the same time.
