45. Ch 3 Review 1. C 2. A 3. D 4. A 5. C 6. B

46. 7. What is a renewable resource? What is a nonrenewable resource?  Renewable is either always available or is naturally replaced in a reasonable amount of time.  Nonrenewable is not replaced in a useful time frame.

47. 8. Describe how environmental decisions are made.  You first have to weigh out the ecological and economical costs and benefits. Then, make a decision.

48. 9. How does the idea of a sustainable yield pertain to forestry and fisheries?  Both forests and fisheries are living resources that need to be around for our future.  In a sustainable forest after trees are harvested, young trees are planted. Also selective cutting can be used to ensure the future supply.  Fisheries can set limits, change fishing methods, use aquacultures, or find new resources in order to provide a sustainable yield.

49. 10. Describe one way that overfishing can be prevented.  Use aquacultures  Set fishing limits

50. 11. Why is gene pool diversity important to the survival of a species?  Species with diverse gene pools are better able to adapt to changes in the environment.

51. 12. Explain how habitat destruction affects species.  Species loose the places to find food and shelter. If they cannot find a substitute niche, the will either have to move or die out.

52. 13. Describe the importance of biodiversity to drug research,  Biodiversity helps prevent species from becoming extinct and we need the wild species to discover new medicines.
