1. NONRENEWABLE AND RENEWABLE RESOURCES

2. HMMMM.... What do you think nonrenewable resources are? Break it down... Nonrenewable? Resource?

3. NONRENEWABLE RESOURCES A nonrenewable resource is a natural resource that cannot be re-made or re-grown at a scale comparable to its consumption.

4. NUCLEAR ENERGY Nuclear fission uses uranium to create energy. Nuclear energy is a nonrenewable resource because once the uranium is used, it is gone!

5. COAL, PETROLEUM, AND GAS Coal, petroleum, and natural gas are considered nonrenewable because they can not be replenished in a short period of time. These are called fossil fuels.

6. WHAT WAS THE DIFFERENCE BETWEEN COAL AND OIL/GAS?

7. HMMMM.... what are renewable resources?

8. RENEWABLE RESOURCES Renewable resources are natural resources that can be replenished in a short period of time. ● Solar ● Geothermal ● Wind ● Biomass ● Water

9. SOLAR Energy from the sun. Why is energy from the sun renewable?

10. GEOTHERMAL Energy from Earth’s heat. Why is energy from the heat of the Earth renewable?

11. WIND Energy from the wind. Why is energy from the wind renewable?

12. BIOMASS Energy from burning organic or living matter. Why is energy from biomass renewable?

13. WATER or HYDROELECTRIC Energy from the flow of water. Why is energy of flowing water renewable?

14. SUMMARY What are the differences between nonrenewable and renewable resources?

15. Date : 16/10/2015 Chapter 4: Rethinking how we view and use natural resources

16. Learning goals Differentiate among the different types of resources Understand the effective resource management in Canada

17. A resource is any part of the total stock of the natural environment that becomes useful to people. The natural resources used by a society reflect the technological level of the people. Resources can be classed as renewable, non-renewable, and flow largely based upon how long it takes to replenish them (apart from finding new sources)

18. Define: Find definitions from your textbook (Ch. 4) total stock resource natural resources flow resources conservation

19. Resources and the 3Rs: 1. None of the 3Rs:1. None of the 3Rs: 2.Recycling2.Recycling 3.Reusing :3.Reusing : 4.Reducing :4.Reducing :

20. Resources and the 3Rs None of the 3Rs: Landfills and the Burning of waste represent the worst possible use of resources. The aim is to create less waste and to cut down on these kinds of disposal

21. Recycling Recycling is a good start because material is used again; however, energy is still required to collect and reprocess the recycled material

22. H.W. Due on Monday 19 th October pg.95 ques. 1,2,3

23. Date : 19/10/2015 Chapter 4: Rethinking how we view and use natural resources

24. Solve questions 1, 2

25. Question1: Classify these resources as renewable, non renewable, flow or other Coal forests Fertile soil gold Fish iron ore Natural gas river flow Scenery Sunlight wind

26. 1. Answer: Renewable: fertile soil, fish, forests Non-renewable: coal, natural gas, gold, iron ore Flow: sunlight, river flow Other: scenery

27. Question 2.

28. Answer 2: Some things that might be included are the following: smell noise chemicals leaching into the water table doesn’t look nice heavy truck traffic easy dumping of garbage jobs taxes

29. Date : 20/10/2015 Chapter 4: Rethinking how we view and use natural resources

30. Learning goals 1.Evaluate the most effective category of the 3Rs in terms of potential resource savings and argue why it has been difficult for society to focus on this category. 2. Evaluate ways in which Canada’s resource use can become more efficient by offering solutions that reduce resource consumption. 3. Strategies that industries and governments have implemented to increase the sustainability of Canada’s natural resources

31. Continued… Reusing :Reusing : It is better because the cost of more items is avoided Used clothing store. Question: What are 2 examples of costly products that we often reuse? We would never think about throwing out houses or cars when we are finished with them.

32. Question: Explain some of the things governments and non profit organizations could do to help promote the concept of reuse. In some communities, one garbage night a month is designated for people to put out items that still have a useful life and may be picked up by others. Non-profit groups, such as Goodwill and Habitat for Humanity (Restore), already do a good job of encouraging reuse, but there is still room for expansion both in terms of geographic coverage and what items are available to sell.

33. Reducing :Reducing : Reducing is best because fewer new items are required, thus saving the energy and materials to manufacture them

34. question Do you think companies are concerned with protecting the environment when they choose to reduce resource use? Explain why they might be. What other reasons might they have for reducing the use of resources?

35. Answer: Companies have the primary responsibility to maximize profits for their shareholders while also obeying all laws. There is nothing in this responsibility to suggest that they should reduce resource use, except to reduce costs. The owners and managers of most companies do want to behave ethically. As a result and given the choice, they will choose the one with the least environmental impact. As well, companies benefit from being seen as responsible corporate citizens.

36. Rethinking Our Use of Resources By rethinking daily choices, individuals can make lifestyle changes that add up to great resource savings, e.g., eliminating disposable cups and water bottles Companies can reduce their operating costs and reduce resource use by rethinking all aspects of the business.

37. Governments can use either a carrot (rewards) or a stick (punishments) approach to create change, e.g., waste disposal, the fuel economy of vehicles Text book Pg.98

38. Balanced Approach Conservation: The wise use of resources

39. Viewpoints: Resources Use: Then and Now Viewpoint 1 Things were better in the past People were more environmentally friendly: homes were smaller, they had fewer electrical appliances, they walked more and drove less, They ate locally and bought things that lasted

40. Viewpoint 2 Things are better today We have less impact on the environment: more home insulation, Energy-saving appliances and fuel- efficient cars, fewer single-family homes, more general concern about the environment
