3. Natural Resources What is a natural resource? Materials or substances that occur in nature Used for economic gain by humans Categories for natural resources Renewable- can be replenished if not overused Non-renewable- cannot be replaced once used Image obtained from: http://www.mrshultz.com/lessons/economicresources/NaturalResources.JPG

4. Classifying Resources RenewableNon-renewable

5. Living Renewable Resources Plants Crops Trees Animals Livestock Fish Game Dead plants/animals Biomass- organic matter that can be used as fuel Image obtained from: http://www.ericsonlivestock.com/MPj01443820000[1].jpg

6. Non-Living Renewable Resources Air Wind Molecular composition Water Flowing water (tides, rivers) Fresh (drinkable) Salt (not drinkable) Image obtained from: http://www.w8themes.com/wp-content/uploads/2013/09/Waterfall-Wallpaper.jpg

7. Non-Living Renewable Resources Soil Used for crops Nutrient quality of soil Heat Heat from Earth- geothermal Heat from Sun- sunlight Image obtained from: http://www.freeartwallpapers.com/wp-content/uploads/2014/08/bright-sunlight-rays-wide-wallpaper-338040.jpg

8. Non-Renewable Resources Fossil Fuels Coal Oil & petroleum Natural gas Raw materials Minerals Precious metals Land (physical space) Image obtained from: http://joysofdickandjune.files.wordpress.com/2011/01/kennecott-copper-mine-98.jpg

9. Problems With Renewable Resources Resource exploitation- consumed faster than can be replenished Overharvesting- fishing, marine life Deforestation- forests, woodlands Fresh water loss- glacial melts, droughts Soil loss- poor farming techniques?

10. Problems With Non-Renewable Resources Environmentally unfriendly- fossil fuels Limited in supply- once used up, they’re gone Scarcity- little or a lot? Accessibility- can people get to it? World distribution- even or uneven? Graph courtesy of British Petroleum, 2008

11. Activity: Scarcity, Accessibility, Distribution Rich countries Private cars Packaged foods, sodas, candy Disposable materials Middle countries Bikes, buses Grain, water Durable materials Poor countries Walking, animals Insufficient grain, unsanitary water Local biomass for materials Image obtained from: http://www.fao.org/News/1998/img/worl-e.gif
