Transcript of "EE Chapter 12 "People and Their Needs""

  1. 1. People And Their Needs Chapter 12
  2. 2. 12.1 A Portrait of Earth <ul><li>Biomes – The interactions among organisms and abiotic factors give rise to distinct ecosystems. </li></ul>
  3. 3. 12.1 A Portrait of Earth Systems and Connections <ul><li>Climate is determined primarily by the interaction of air and water. </li></ul><ul><li>Physical laws govern Earth’s systems through matter and energy. </li></ul><ul><li>Ocean circulation, plate tectonics, and global temperature changes all result in dramatic changes in ecosystems. </li></ul>
  4. 4. 12.1 A Portrait of Earth Systems and Connections <ul><li>Earth is a closed system when it comes to matter. Only a tiny bit enters in and leaves. </li></ul><ul><li>Earth is an open system with respects to energy due to the exchange among the sun, Earth, and space. </li></ul><ul><li>The sun’s energy powers ocean currents, cloud formations, and plant growth. </li></ul>
  5. 6. 12.1 A Portrait of Earth Perceptions of Eart <ul><li>Gaia hypothesis states that Earth functions like a single, living organism that regulates itself to maintain life. </li></ul><ul><li>Earth is thought of as a living organism. </li></ul><ul><li>Gaia hypothesis disagrees with the views of most modern industrial societies. </li></ul>
  6. 7. 12.2 Human Societies <ul><li>Fully modern Homo sapiens first evolved from ancestral humans about 35000 years ago. </li></ul><ul><li>They were intelligent, artistic (painters), and handy (intricate tools). </li></ul>
  7. 8. 12.2 Human Societies Hunter-Gatherer Societies <ul><li>A society in which people gather natural food, hunt, and are nomadic. </li></ul><ul><li>Small impact on the environment because of low population density which allows the environment to regenerate. </li></ul><ul><li>They don’t drain the resources! </li></ul>
  8. 9. 12.2 Human Societies Agricultural Societies <ul><li>A society in which crops are grown and people have specialized roles. </li></ul><ul><li>The early, rapid growth rate was a result of an increased food supply. </li></ul><ul><li>The invention of the plow led to the expansion of the food supply. </li></ul>
  9. 10. 12.2 Human Societies Agricultural Societies <ul><li>As farming became more productive, more people were able to manufacture products. </li></ul><ul><li>Societies that fell like the Babylonian Empire were a result of unwise land-use practices resulting in desertification. </li></ul>
  10. 11. 12.2 Human Societies Industrial Societies <ul><li>A society in which the production of food and other products is performed by machines, demanding large amounts of energy and resources. </li></ul><ul><li>Machines replaced craftspeople. </li></ul>
  11. 12. 12.2 Human Societies Industrial Societies <ul><li>The increase of industrialization was accompanied by increased use of fossil fuels. </li></ul><ul><li>Food Supply, Human Population and Manufactured Goods all increased during this time. </li></ul>
  12. 13. 12.3 Sustainable Development <ul><li>Resource – Water, Wind and Sunlight </li></ul><ul><li>Human populations are subject to natural controls. </li></ul><ul><ul><li>Ex. Temperature, Precipitation, Crops, Oxygen </li></ul></ul>
  13. 14. 12.3 Sustainable Development The Frontier Ethic <ul><li>Founded on the assumption that human society is separate from nature. </li></ul><ul><li>Not an Environmentally Friendly Ethic! </li></ul><ul><li>Examples of Frontier Ethic activities would include clear cutting forests, building dams, and draining wetlands. </li></ul>
  14. 15. 12.3 Sustainable Development The Sustainable Development Ethic <ul><li>An ethic that meets current global human needs without limiting the ability of future generations to meet their own needs. </li></ul><ul><li>Renewable Resources – A resource that regenerates quickly. (Ex. Water, Wood,Sun) </li></ul><ul><li>Nonrenewable Resources – A resource that cannot regenerate quickly. (Ex. Oil, Ores) </li></ul><ul><ul><li>They are running out!!! </li></ul></ul>
