1. NATURAL RESOURCES & CONSERVATION

2. E.Q. – How can water, soil & air be recycled?
Standard S6Ej. Describe methods for conserving natural resources such as water, soil, and air.

3. NATURAL RESOURCE
Natural Resource - Any natural material that is used by humans or
Resources that the Earth provides for you
EX: Water, Petroleum, Minerals, Forests

4. CONSERVING NATURAL RESOURCES
To conserve natural resources, you should try to use them only when necessary.
3 R’s
Reduce
Reuse
Recycle

5. SOIL POLLUTION How can soil be lost or damaged?
Exhausted – lose fertility because crops planted year after year.
Polluted – mining, chemical spills, HUMANS
Erosion – wind, water
Desertification – once wet area, undergoes drought conditions OR grazing animals OR cutting trees

6. HOW CAN SOIL BE CONSERVED?
Soil conservation is the management of soil to prevent destruction.
Contour Plowing
Crop Rotation
Conservation Plowing
Windbreaks
Leaving soil fallow

7. Contour Plowing plowing fields along curves of slopes

8. Conservation Plowing dead weeds and stalks are left in the ground from year to year

9. Crop Rotation plant different crops in a field from year to year

10. Windbreak trees planted along the edge of a field

11. Terracing
Prevents erosion from heavy rains on steep hills

12. WATER POLLUTION How can water be lost or cause damage?
Point-Source Pollution- pollution that comes from one specific site. EX: leak from a sewer pipe

13. WATER POLLUTION How can water be lost or cause damage?
Nonpoint-source Pollution – Pollution that comes from many sources; Reaches bodies of water as runoff
EX: street gutters, fertilizers, eroded soil, drainage from mines

15. How can Water be conserved?
By using only the water needed
By recycling water
By using drip irrigation systems.
Waste water can be treated by sewage treatment plants and septic systems

16. Air Pollution How can Air cause damage or loss?
Air Pollution - The contamination of the atmosphere by the introduction of pollutants from human and natural sources

17. Air Pollutants PRIMARY POLLUTANTS Industrial emissions Vehicle Exhaust
Volcanic Ash
SECONDARY POLLUTANTS
The formation of smog

18. SOURCES OF HUMAN-CAUSED POLLUTION
Industrial & Indoor Air Pollution
Acid Precipitation
The Ozone Hole

19. How Can Air Be Conserved?
By legislation, such as the Clean Air Act
By Technology such as scrubbers
- devices used to remove pollutants before they are released by smokestacks
By changes in Lifestyle
