Bellringer List as many uses of forest products that you can think of. What energy sources do you use? What adjustments would you have to make if those were unavailable?
Section 1: World Resources 1. How do renewable resources and nonrenewable resources differ? 2. What energy sources are available to individuals and nations?
Natural Resources A resource is something of value Capital resources vs. human resources Natural Resources: ◦Materials in the natural environment that people value and use to satisfy their needs ◦Renewable Resources (Constantly being replaced) Ex: soil, water, Sun ◦Nonrenewable Resources (Cannot be replaced) Ex: fossil fuels (coal, oil, natural gas), iron, copper, gold, silver, uranium Recycle
Energy Resources Mostly we use Nonrenewable resources!!! Oil – most likely to run out in the next 100 years Coal – can last up to 200 years
Energy Sources Cont… Nuclear Energy ◦Fission – splitting of uranium atoms in a nuclear reactor to release stored energy ◦Threats of Nuclear Energy…
What problems will arise out of a lack of energy sources? What will people do to find more energy?
Energy Sources Cont… Other Energy Sources ◦Water Power (Dams), ocean tides, wind, solar, geothermal energy Distribution of Energy ◦Uneven distribution ◦Population centers develop around energy sources ◦Import vs. Export
Section 2: World Economic Activity Global Trade Patterns ◦Not all nations have the same resources ◦Exports – what nations bring in ◦Imports – what nations send out ◦Trade Balance Balance between exports and imports National Debt Taxes on imports and quotas ◦Trade Routes Geography, technology, international relations Electronic Transactions
