This document discusses different types of land use and soil management, waste production and disposal methods, as well as various forms of pollution including water, air, and indoor pollution. It addresses topics such as soil layers, erosion, fertilizer use, desertification, recycling, disposal methods like incineration and landfilling, sources of household, agricultural, and industrial water pollution. It also covers air pollutants like smog from vehicles, acid rain from factories, and indoor pollutants such as carbon monoxide and radon. Solutions proposed include reducing pollution through emissions controls, using public transportation, and walking or biking.

2. I. Land and Soil A. Use 1. Agriculture 2. Mining 3. Development

3. B. Soil 1. Layers i. Litter ii. Topsoil iii. Subsoil iv. Bedrock

4. C. Soil Management 1. Erosion 2. Nutrient Depletion i. Fertillizer ii. Crop rotation

5. 3. Desertification i. Climate change = Loss of moisture ii. Loss of nutrients = Overuse

6. 4. Land Reclamation

7. II. Waste A. U.S. Numbers 1. 2.5 million plastic bottles every hour 2. 2 kg of trash everyday 3. 2.8 million plastic bags 4. 230 million car tires

8. B. Disposal 1. Incineration: Burn it i. Get energy from waste ii. Air pollution 2. Landfill i. Leachate ii. Sanitation

9. C. Recycling Biodegradable (breakdown in soil) 2. Metals 3. Plastics 4. Glass 5. Paper

10. D. Human Factors 1. Reduce – Use Less! 2. Reuse – Use object more than one time 3. Recycle – Use to build something else 4. Composting – Biodegrade foods

11. E. Hazardous Wastes 1. Types i. Toxic/poisonous ii. Explosive iii. Flammable iv. Corrosive v. Radioactive

12. III. Water Pollution Pollution 1. Household 2. Agricultural 3. Industry 4. Sediments 5. Heat 6. Oil and Gas

13. B. Cleaning 1. Sewage Treatment 2. Reduce Pollution 3. Clean up spills 4. Don’t throw chemicals in trash

14. IV. Air Pollution Smog 1. Cars and Trucks (nitrogen) 2. Temperature Inversion

15. B. Acid Rain 1. Factories and power plants (sulfur)

16. C. Indoor Pollution 1. Carbon Monoxide i. Burning gas 2. Radon i. Ground Gas

17. D. Reducing Pollution 1. Emissions from Factories “Scrubbers” 2. Emissions from Cars “Catalytic Converter” 3. Public Transportation 4. Walk 5. Ride a bike
