5. “Renewable” depends on context Ex: “_____________” forests provide a unique _______ and are home to many species that don’t live in other types of forests RENEWABLE RESOURCES http://en.wikipedia.org/wiki/Old_growth_forest Old growth habitat

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

8. ___________________ can affect the quality and supply of renewable resources such as _______________________________ How can we provide for our needs while maintaining ecosystem goods and services that are renewable? land, forests, fisheries, air, and fresh water THE BIG QUESTION ? HUMAN ACTIVITIES

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

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

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

12. 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. SOIL renewable humus TOPSOIL

13. 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

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

15. Cover Crops Legumes, grasses, and other cover crops recycle soil nutrients, reduce fertilizer need, and prevent weed growth. 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. Biological Pest Control The use of predators and parasites to control destructive insects minimizes pesticide use as well as crop damage 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. Crop Rotation Different crops use and replenish different nutrients. By rotating crops, the loss of important plant nutrients is decreased. ABC Yr. 1 Yr. 2 Yr. 3 Section 6-4 corn alfalfa oats alfalfa (plowed in) Sustainable Agriculture
