1. Natural Resources Chapter 1, Sections 3-4

2. A.Biological Resources Most important People use chiefly for food Trees-absorb pollution, produce O2, build homes, furniture Rely on Air, Sunshine, H2O Soil-Fertile Soil(good for crops) – If a country has it, then they don’t worry about money, if they don’t have good crops then they have to trade of borrow for them.

3. B. Mineral & Fuel Minerals are found in rocks – 100 common ones are used by humans – graphite for pencils, cement, fertilizers for farming Fossil Fuels (provide heat and energy) – Not made from rocks – Formed by prehistoric plant & animal remains – Gather by mining or drilling into Earth’s crust – Examples are coal, oil, petroleum, natural gas

4. Nonrenewable vs. Renewable Resources Renewable resources can be made again by nature or in a practical amount of time – Fresh H 2 O and soil Nonrenewable resources take too long to replace or they aren’t at all replaceable)

5. How do you save natural resources? Conservation of all resources There is a scarce supply of fossil fuel, try to use less Recycle – aluminum & steel cans – Glass & Plastic containers – Paper – Petroleum products (old oil, etc.) By recycling over 1.2 million tons of steel in 2005, Pennsylvanians saved............. 1.4 million tons of iron ore 829,786 tons of coal 71,124 tons of limestone Through recycling newsprint, office paper and mixed paper, we saved the equivalent of 78 million tree seedlings grown for 10 years.

6. Clean Energy (little pollution) Energy from wind, ocean, sun Use Old Resources

8. Valuable Reusables Building Materials – Lumber, tools, windows, doors, light fixtures, paint, plumbing supplies and fixtures, architectural pieces, fencing, hardware, and many other items needed for constructing or refurbishing a building can be found used. Office Furniture and Supplies – Desks, tables, chairs, filing cabinets, credenzas, shelving units, stacking trays, tape dispensers, notebook binders and other equipment and supplies can be reused in offices, schools, hospitals, non- profit organizations and others. Computers and Electronics – Personal computers, printers, fax machines, televisions, video cassette recorders can be reused in business, personal, and non-profit environments. Art Materials – Fabric, paint, lumber, stage props, and a wide variety of other items can be used for school or cultural organization creative projects. Medical Equipment and Supplies – Equipment and supplies that are obsolete to one hospital, clinic or organization may find a home in another facility, especially those in less-industrialized nations. Surplus Food Items and Equipment – Boxed, bagged, canned and even prepared food from grocery stores, warehouses, manufacturers' over-runs and discontinued items, catered events, restaurants can be reuse by homeless shelters, soup kitchens, and other organizations serving disadvantaged people. Stoves, refrigerators, freezers, and other items can also be found used. Household Items – Appliances, clothing, furniture, dishes, vehicles, paint, and virtually anything else for the home can be found by shopping reused instead of brand new. And in most cases, at a significantly lower price. Another form of reuse is shopping specialty stores that sell antiques or vintage items. Shopping and holding garage and yard sales are other popular forms of reuse.

10. Supply & Demand Why Natural resources matter – Value depends on how much there is and how many people want it – Plentiful resources make country independent, less trade necessary
