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
RENEWABLE RESOURCES

• A Natural Resource that can be replaced at the
  same rate at which the resource is used.
• EX Trees,Wind, Water
• Although many resources are renewable, they still
  can be used up before they can be renewed.

5
Nonrenewable Resources

• A resource that forms at a rate that is much
  slower than the rate at which it is consumed.
• A fossil fuel is a nonrenewable energy resource
  formed from the remains of plants animals that
  lived long ago.
• EX Coal, Petroleum (Oil), Natural Gas
• Once theyre gone, theyre gone!!

6
CONSERVING NATURAL RESOURCES

• To conserve natural resources, you should try to
  use them only when necessary.
• 3 Rs
• Reduce
• Reuse
• Recycle

7
SOIL POLLUTIONHow 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

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

9
Contour Plowing plowing fields along curves of
slopes
10
Conservation Plowingdead weeds and stalks are
left in the ground from year to year
11
Crop Rotationplant different crops in a field
from year to year
12
Windbreaktrees planted along the edge of a field
13
Terracing

• Prevents erosion from heavy rains on steep hills

14
WATER POLLUTIONHow can water be lost or cause
damage?

• Point-Source Pollution- pollution that comes from
  one specific site. EX leak from a sewer pipe

15
WATER POLLUTIONHow 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

17
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

18
Air PollutionHow can Air cause damage or loss?

• Air Pollution - The contamination of the
  atmosphere by the introduction of pollutants from
  human and natural sources

19
Air Pollutants

• PRIMARY POLLUTANTS
• Industrial emissions
• Vehicle Exhaust
• Volcanic Ash
• SECONDARY POLLUTANTS
• The formation of smog

20
SOURCES OF HUMAN-CAUSED POLLUTION

• Industrial Indoor Air Pollution
• Acid Precipitation
• The Ozone Hole

21
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
