Title: USING THE EARTHS RESOURCES


1
USING THE EARTHS RESOURCES
  • AGRISCIENCE AND TECHNOLOGY

Modified by Georgia Agricultural Education

July, 2002
2
OBJECTIVES
  • DEFINE ENVIRONMENT AND NATURAL RESOURCES
  • EXPLAIN ECOSYSTEMS
  • EXPLAIN AND GIVE EXAMPLES OF RENEWABLE NATURAL
    RESOURCES
  • EXPLAIN AND GIVE EXAMPLES OF NON-RENEWABLE
    NATURAL RESOURCES

3
OBJECTIVES CONT.
  • EXPLAIN POLLUTION AND IDENTIFY SOURCES OF
    POLLUTION.
  • DEFINE RECYCLING AND LIST EXAMPLES.
  • IDENTIFY SOURCES OF POLLUTION IN AGRICULTURE AND
    NAME RULES TO FOLLOW IN PREVENTING AGRICULTURE
    POLLUTION.

4
FACTS TO THINK ABOUT
  • ONE IN THREE PEOPLE IN THE WORLD DONT HAVE
    ENOUGH FOOD TO EAT.
  • 12 MILLION PEOPLE DIE OF STARVATION EACH YEAR.
  • BY THE YEAR 2030 THE WORLDS POPULATION WILL
    DOUBLE AT 10 BILLION PEOPLE.

5
DEFINITION OF ENVIRONMENT
  • ENVIRONMENT IS ALL OF THE FACTORS THAT EFFECT THE
    LIFE OF A LIVING THING
  • IT IS EVERYTHING EXTERNAL TO A PLANT OR ANIMAL.

6
NATURAL RESOURCES
  • NATURAL RESOURCES ARE THE NATURALLY OCCURING
    THINGS THAT SUPPORT LIFE, PROVIDE FUEL OR ARE
    USED IN OTHER WAYS BY HUMANS.
  • SOIL, WATER, AIR, MINERALS, PLANTS, AND ANIMALS
    ARE EXAMPLES.

7
BIOSPHERE
  • BIOSPHERE IS THE AREA OF THE EARTH THAT SUPPORTS
    LIFE
  • EXTENDS ONLY A FEW FEET ABOVE THE EARTH AND INTO
    THE OCEANS, DEPENDING ON THE KIND OF LIFE.

8
HABITAT
  • HABITAT IS A PLACE A PLANT OR ANIMAL LIVES UNDER
    NATURAL CONDITIONS.
  • EXAMPLE ZOOS MAY HAVE TO CREATE A HABITAT FOR
    A SPECIFIC ANIMAL.

9
ECOSYSTEM
  • ECOSYSTEM IS ALL OF THE PARTS OF A PARTICULAR
    ENVIRONMENT
  • SOME PARTS ARE LIVING (BIOTIC FACTORS)
  • SOME PARTS ARE NONLIVING (ABIOTIC FACTORS)

10
EXAMPLES OF BIOTIC FACTORS
  • PLANTS
  • ANIMALS
  • OTHER LIVING THINGS
  • SOME HAVE A SYMBIOSIS RELATIONSHIP WITH EACH
    OTHER
  • SOME DO NOT RELATE WELL WITH EACH OTHER ( WOLVES
    AND SHEEP)

11
EXAMPLES OF ABIOTIC FACTORS
  • WATER
  • TEMPERATURE
  • SUNLIGHT
  • SOIL CHARACTERISTICS
  • LAY OF THE LAND
  • THEY DETERMINE WHICH PLANTS AND ANIMALS CAN LIVE
    IN AN ECOSYSTEM

12
IDEAL ECOSYSTEM WITHIN A STREAM PASSING THROUGH A
MEADOW
  • WATER FREE OF POLLUTION
  • FISH AND OTHER LIFE IN THE WATER
  • FERTILE SOIL SURROUNDING THE STREAM
  • PLANTS GROWING ON THE SURROUNDING LAND
  • INSECTS IN THE PLANTS
  • BIRDS IN THE AIR ABOVE

13
EXAMPLE OF A NICHE
  • NICHE IS A WAY A PLANT AND ANIMAL HAS ITS OWN
    SPECIAL WAY OF LIVING
  • A BEAVER IS AN EXAMPLE
  • A VENUS FLY TRAP IS A PLANT EXAMPLE

14
FOOD CHAIN
  • FOOD CHAIN IS THE SEQUENCE IN WHICH ALL LIVING
    THINGS IN AN ECOSYSTEM GET THEIR FOOD
  • ALSO MAY BE REFERRED TO AS THE CYCLE OF NATURE

15
SUSTAINABLE AGRICULTURE
  • IS USED TO DESCRIBE ALL OF THE THINGS DONE IN
    AGRISCIENCE TO MAINTAIN THE ABILITY TO PRODUCE
    FOOD, FIBER AND SHELTER

16
SUSTAINABLE AGRICULTURE INVOLVES
  • PROTECTING THE SOIL, AIR, AND WATER
  • MAINTAINING WILDLIFE HABITAT
  • USING PESTICIDES AND FERTILIZERS WISELY
  • DISPOSING OF WASTES PROPERLY

17
NATURAL RESOURCES
  • RENEWABLE
  • SOIL
  • WATER
  • WILDLIFE/ FISH
  • FOREST
  • AIR
  • NON-RENEWABLE
  • COAL
  • PETROLEUM
  • NATURAL GAS
  • MINERALS

18
WAYS TO RENEW SOIL
  • USE SOIL CONSERVATION MEASURES TO KEEP THE SOIL
    IN PLACE
  • SOIL TEST AND MAINTAIN SOIL FERTILITY

19
WAYS TO RENEW/CONSERVE WATER
  • DONT WASTE WATER
  • FARM PONDS
  • TERRACES
  • CROP RESIDUE
  • TREAT WASTE WATER AND RE-USE

20
WAYS OF RENEWING WILDLIFE/FISH
  • RESTOCKING OF FISH
  • EXTEND OR LIMIT TIME OF HUNTING SEASON
  • RELOCATION OF CERTAIN SPECIES OF ANIMALS

21
WAYS TO RENEW FOREST
  • REPLACE TREES BY PLANTING CLEARCUT AREA
  • HARVEST TREES BY A DIAMETER LIMIT (18 DBH)
  • COMMERCIAL FOREST OWNED BY GEORGIA-PACIFIC AND
    WEYERHAUSER MANAGE LARGE TRACTS OF LAND FOR
    TIMBER.

22
INCREASING AIR QUALITY
  • REDUCE EMISSIONS (WASTES INTO THE AIR) COMING
    FROM FACTORIES AND CARS, AND EQUIPMENT
  • DO NOT TRY TO BURN BATTERIES (CAINTAINS
    CADMIUM-HEAVY METAL)
  • CONTROLLING SMOKE

23
ENVIRONMENTAL POLLUTION
  • ALL THE WAYS THAT PEOPLE CONTAMINATE THEIR
    ENVIRONMENT
  • HUMANS CAUSE MOST POLLUTION
  • SOURCES INCLUDE TOXIC PRODUCTS, SOIL LOSS, WASTE
    PRODUCTS, DISCHARGED WATER, JUNK AND LITTER

24
TOXICOLOGY
  • STUDY OF THE EFFECTS OF POISONS ON LIVING THINGS
  • EFFECTS OF TOXINS ARE ACUTE (SHORT-TERM EXPOSURE)
    AND CHRONIC (LONG-TERM EXPOSURE)

25
MAJOR SOURCES OF TOXINS
  • EXHAUST FROM ENGINES
  • BURNING MATERIALS
  • AGRICULTURAL CHEMICALS

26
SOIL LOSS
  • WIND EROSION
  • WATER EROSION
  • SOIL PARTICLES GET INTO THE AIR, STREAMS, LAKES
    AND CAUSE POLLUTION

27
WASTES PRODUCTS
  • GARBAGE FROM HOMES/RESTAURANTS
  • LEFT-OVER MATERIALS AT FACTORIES
  • CROP REMAINS AND LIVESTOCK WASTES ON FARMS
  • 1300 LBS. OF WASTE/PERSON/YEAR

28
DISCHARGED WATER
  • EFFLUENTS - DISCHARGED WATER AFTER IT HAS BEEN
    USED IN A FACTORY OR PROCESS OF SOME TYPE.
  • SUBSTANCES- WASTE BLOOD FROM MEAT PROCESSING
    PLANT
  • TEMPERATURE- POWER PLANT RELEASING WATER INTO
    STREAMS

29
EFFLUENTS CAUSING POLLUTION
  • AMOUNT - RELEASING TOO MUCH WATER INTO STREAMS
    OTHER METHODS OF DISPOSAL MAY BE NEEDED
  • HUMAN WASTES - SOME SMALL TOWNS OR OLDER
    RESIDENTS MAY NOT HAVE SEWAGE TREATMENT PLANTS OR
    SEPTIC SYSTEMS

30
METHODS OF WASTE DISPOSAL
  • LANDFILLS 80 OF THE WASTE IN US IS DISPOSED
    IN LANDFILLS
  • INCINERATION 9 OF THE WASTE ARE INCINERATED
  • RECYCYLING COMMON ITEMS INCLUDE PAPER,
    ALUMINUM,TIN CANS AND GLASS.

31
SOURCES OF AGRICULTURAL POLLUTION
  • INTRODUCING PESTS BROUGHT INTO U.S. ON SEED,
    PLANTS, FRUIT OR OTHER PRODUCTS
  • EXOTIC PLANTS OR ANIMALS RELEASE OF PLANTS OR
    ANIMALS MAY DAMAGE EXISTING PLANTS/ANIMALS
  • CHEMICALS IMPROPER USE OF AGRICULTURAL CHEMICALS

32
SOURCES OF AG POLLUTION
  • WASTE WATER EXCESS WATER FROM IRRIGATION, FISH
    PONDS, FOOD PROCESSING PLANTS.
  • PROCESSING WASTES CHICKEN FEATHERS, INTERNAL
    PARTS OF ANIMALS, VEGETABLES, SAWDUST, AND TREE
    BARK.
  • NEW LIFE FORMS NON-NATURAL FORMS OF
    PLANTS/ANIMALS

33
STEPS TO PREVENT POLLUTION
  • KNOW REGULATIONS
  • FOLLOW RULES
  • USE PROPER STORAGE
  • WASTE CONTROL
  • USE CHEMICALS PROPERLY
  • DISPOSE OF CONTAINERS PROPERLY
  • USE SAFETY
