  1. HUMAN IMPACT on the BIOSPHEREPart 2Renewable and Non-renewable Resources

  2. RENEWABLE regenerate cycles ________________ RESOURCES can ____________ if they are alive OR be replaced by biogeochemical ________ if they are non-living http://www.inclusive.co.uk/downloads/images/pics2/tree.gif http://www.sfu.ca/aq/archives/Nov2007/features/fish_story.html http://www.navitron.org.uk/wind/600kw.JPG

  3. RENEWABLE RESOURCES “Renewable” depends on context Ex: An _________tree can be re-grown, but a __________ of trees in an ecosystem may NOT be replaceable individual population http://image.guardian.co.uk/sys-images/Guardian/Pix/gallery/2002/08/30/deforestedland.jpg

  4. NONRENEWABLE RESOURCES unlimited Renewable does NOT mean __________________ Ex: ______________ is a renewable resource but can become limited by _______ OR ________ Fresh water drought overuse http://earth.ooups.com/uk/images/100/tapwater.jpghttp://www.wrightwoodcalif.com/watershort/ConserveWater.JPG

  5. NONRENEWABLE RESOURCES NOT BE replenished can ___________________________ by natural processes http://www.greenpeace.org/raw/image_full/international/photosvideos/photos/illegal-deforestation-and-land.jpg http://www.npr.org/news/images/2005/aug/16/pumping_gas200.jpg

  6. THE BIG QUESTION ? land, forests, fisheries, air, and fresh water quality and supply Human activities can affect the _____________________of renewable resources such as: How can we provide for our needs while maintaining ecosystem goods and services that are renewable?

  7. One ANSWER to ? SUSTAINABLE DEVELOPMENT = ____________________________ It’s a way of _________ natural resources __________________ them and providing for human needs WITHOUT causing long term __________________ using without depleting environmental harm

  8. http://www.newtonswindow.com/problem-solving.htm REMEMBER RESOURCE A __________________ is anything an organism needs for life NATURAL RESOURCES = LAND AIR WATER FORESTS http://coweeta.ecology.uga.edu/coweeta_photographs/erosion.htm http://www.lenntech.com/images/discharge.gif

  9. LAND RESOURCES space Provide _________ for human communities Provide _____________ for industry http://www.fotogalerie-naturpur.de/pic/land1.html raw materials http://lloydsfunds.com/mining_12.jpg

  10. SOIL LAND RESOURCES Land resources include __________ which is a ______________ resource if managed properly. ____________is made of sand, clay, rock, and _________(decayed organisms) and is produced and maintained by interactions between soil and plants growing in it. renewable TOPSOIL humus

  11. LAND RESOURCES Wearing away of topsoil = ____________ is caused by plowing land and removing plant roots Soil erosion http://coweeta.ecology.uga.edu/coweeta_photographs/erosion.htm

  12. Desertification LAND RESOURCES ___________________ = changing of fertile land in dry climates into desert areas caused by farming, overgrazing, and drought http://www.the-human-race.com/images/environment/drought.jpg

  13. Sustainable Agriculture Section 6-4 Controlled Grazing By managing graze periods and herd densities, farmers can improve nutrient cycling, increase the effectiveness of precipitation, and increase the carrying capacity of pastures. Cover Crops Legumes, grasses, and other cover crops recycle soil nutrients, reduce fertilizer need, and prevent weed growth. Biological Pest Control The use of predators and parasites to control destructive insects minimizes pesticide use as well as crop damage A B C Yr. 1 oats alfalfa corn Contour Plowing Contour plowing reduces soil erosion from land runoff. On hilly areas, plowing is done across the hill rather than straight up and down. Yr. 2 Crop Rotation Different crops use and replenish different nutrients. By rotating crops, the loss of important plant nutrients is decreased. alfalfa (plowed in) corn alfalfa Yr. 3 oats alfalfa corn

  14. FOREST RESOURCES wood Provide _________ for products ranging from homes to paper Wood provides _________ in many countries http://www.nature.org/images/sotw_logging.jpg fuel http://www.forestlearn.org/graphics/wood_fuel.jpg

  15. FOREST RESOURCES Forests have been called the “lungs of the Earth” because they remove ________________ and produce ______________ carbon dioxide oxygen http://www.ecoworld.com/air/Images/Photosynthesis.jpg

  16. http://www.gdccc.org/Records/EOY2004/NS%20Salon%20HM%20Brittain%20Roger%20Owl%20in%20Hole%20No%202.jpghttp://www.gdccc.org/Records/EOY2004/NS%20Salon%20HM%20Brittain%20Roger%20Owl%20in%20Hole%20No%202.jpg FOREST RESOURCES nutrients Forests also: Store ___________ Provide_________ Moderate ________ _______soil erosion Protect fresh ______ habitats climate prevent water

  17. deforestation FOREST RESOURCES Loss of forests = ____________ can result in erosion and loss of nutrients preventing regrowth http://www.greenpeace.org/raw/image_full/international/photosvideos/photos/illegal-deforestation-and-land.jpg

  18. HOW DO WE HELP? Sustainable development: • selective harvest of mature trees • replanting of logged areas • tree farms • breeding new, faster growing species

  19. AIR RESOURCES Pollutant ______________ = harmful material that can enter the biosphere through land, air, or water _________ = Mixture of chemicals that appear as a gray-brown haze in the atmosphere smog http://www.cyberolimpiadas.com.sv/proyectos2004/gamma/proyecto3/smog.jpg

  20. AIR RESOURCES fossil fuels Burning __________ releases pollutants that cause smog and other problems in atmosphere. Toxic chemicals like nitrates, sulfates, and particulates can cause ________________ like ___________ breathing problems asthma http://www.cyberolimpiadas.com.sv/proyectos2004/gamma/proyecto3/smog.jpg

  21. SUSTAINABLE DEVELOPMENT • Smokestack “Scrubbers” control emissions • Auto emission standards • Clean air regulations • Reduce use of fossil fuels http://www.alexvisani.com/darkgallery/smog.jpg

  22. FRESH WATER RESOURCES Americans use BILLIONS of gallons of freshwater daily for ________, ________ and ___________________ drinking washing watering crops http://www.thesolutionsite.com/lesson/4601/freshwater.jpg

  23. FRESH WATER RESOURCES renewable Although water is a ______________ resource, the total supply of fresh water is __________. limited http://www.mos.org/oceans/graphics/planet/watercycle.jpg

  24. SUSTAINABLE DEVELOPMENT • Water conservation • Protect wetlands and forests • Water treatment plants • Clean water regulations hhttp://www.romanviii.co.uk/bp/nhpage.asp?pcat=about_us

  25. DON’T FORGET THE WATER WE CAN’T SEE! The PRODUCTION OF: • 1 kg wheat costs 1,300 L water • kg rice costs 3,400 L water • 1 kg eggs costs 3,300 L water • 1 kg beef costs 15,000 L water • 1 cotton shirt costs 2,500 L water • 1000 g of blue jeans costs 10,850 liters water • 1 ton passenger car costs 400,000 liters of water • Building a house uses about 6 million liters of water
