Title: MEETING HUMAN NEEDS IN A CHANGING WORLD


1
MEETING HUMAN NEEDSIN A CHANGING WORLD
  • Principles of Agriculture

2
I can statements for unit 1
  • I can define agriculture.
  • I can define agriscience and discover it in the
    world around us.
  • I can state the major sciences that support
    agriscience.
  • I can describe basic and applied sciences that
    relate to agriscience.
  • I can identify significant historical
    developments in Agriscience.
  • I can evaluate the different agriscience careers
    and their earning potential, training required
    and job descriptions.

3
What do people need to survive?The three human
needs are
  • FOOD
  • FIBER
  • SHELTER

4
Critical VocabularyAgriculture
  • Is defined by the art and science of helping to
    feed, clothe, and beautify mankind.
  • Helps us meet the needs of people.
  • Through science and technology agriculture is
    changing constantly.

5
Agriculture Statistics
  • 1/5 of total jobs in Agriculture are found in
    that areas of production agriculture, farming or
    ranching. While only 15.4 cents of the food
    dollar is the producers share.
  • 4/5 of total jobs in Agriculture are found to be
    in areas of non-farm or non-ranch situations.
  • Approximately 2 of people in the United States
    are actually farmers.
  • The average U.S. farmer produces enough food to
    feed 130 people.

6
Agricultural Engineer
  • Means the application of mechanical and other
    engineering principles in agricultural settings.
    (Ex person that develops the design or pattern
    of something to be constructed.)
  • The use of iron has industrialized the field of
    agriculture for engineers.

7
Agriscience
  • Is defined as the application of scientific
    principles and new technologies to agriculture.
  • This industry provides commodities that are basic
    to life.
  • The products and services that are provided in
    most of the areas in the agriscience wheel of
    fortune seem to flow to originate from
    Agriscience processing, products, and
    distribution.
  • Increase yields in crops such as sugar and rice
    per acre is possible because of new hybrids that
    have been developed.
  • 20 of the careers in agriscience require college
    degrees. (veterinarian, cooperative extension
    agent, soil conservationist, geneticist,
    agriscience teacher, horticulturist, etc.)
  • 20 of all workers in the U.S. are employed in
    the agriscience industries.

8
Horticulture
  • The industry that produces, processes, and
    markets fruits, vegetables and ornamental plants.

9
Forestry
  • industry is growing, managing and harvesting
    trees.

10
Soil science
  • refers to the study of the properties and
    management of soil to grow plants.
  • Agronomy is the science of soils and field crops.
  • In 1972, a pesticide called DDT was banned
    because of its harmful effect on the environment.
  • Horticulture is the science of fruits, vegetables
    and ornamentals.
  • Entomology is the science of insect life.

11
Renewable natural resources
  • Provided by nature that can replace or renew
    themselves. (Examples wildlife, trees, fish,
    etc.)
  • Some occupations may include forester, waterman,
    game trapper, etc.
  • Aquaculture means the growing and management of
    living things in water, such as fish.

12
Animal Science
  • refers to the use of modern principles and
    practice for animal growth and management.
  • Possible Animal science careers include Animal
    breeders, veterinarians, etc.
  • Animal Science concern- mastitis an infection
    of the milk secreting glands of cattle, goats and
    other milk producing animals.

13
Agribusiness
  • Refers to commercial firms that have developed
    with or stemmed out of agriculture.
  • Agriculture Economics-management of agricultural
    resources.

14
Assignment A.) Investigate assigned agriscience
career, determine the earning potential and
identify TWO jobs within this career.B. Explain
why someone in this career field must continue
their education in order to be successful and how
this relates to their earnings.
15
INVENTIONS / IMPROVEMENTS
  • Cyrus McCormick- invented the reaper to cut small
    grain.
  • Thomas Jefferson invented the iron plow.
  • John Deere invented the moldboard plow that was
    made of steel, allowing plowing of soil.
  • Eli Whitney invented the cotton gin to remove
    cotton seeds from cotton fiber.
  • Edmund Quincy invented the corn picker to
    remove ears of corn from stalks.
  • Joseph Glidden invented the barb wire with
    sharp points to prevent animals from touching it.
  • Anna Baldwin invented the milking machine.
  • Benjamin Holt invented the tractor for a source
    of power for belt-driven machines.
  • Combine cuts and threshes grain in the field.

16
How do we live different than someone in a third
world country?
  • Assignment In assigned groups, research your
    assigned country determine the following
  • are farmers
  • Climate/topography
  • Life expectancy
  • Population breakdown
  • Mechanizations and advancements in technology
    utilized. (ex GMOs, equipment, etc.)

17
After completing your research develop a poster
or power point on your country including all of
your information. (Rubric will be given)
18
FACTORS THAT DETERMINECONSUMER PREFERENCE
  • CLIMATE - TYPE OF WEATHER
  • CUSTOMS EXAMPLE TYPE OF FOOD THAT PEOPLE ARE
    NOT ALLOWED TO EAT.
  • STANDARD OF LIVING - INCOME OF THE PEOPLE AND
    PRODUCTS AVAILABLE TO THEM

19
CONTRASTS BETWEEN NATIONS IN AGRICULTURE
  • MECHANIZATION- TRACTORS,EQUIP.
  • IMPROVED CROPS - HIGHER YIELDS
  • COMMERCE - TRANSPORTATION, STORAGE FACILITIES,
    METHODS OF BUYING AND SELLING PRODUCTS
  • EDUCATION OF PEOPLE - VARY
  • SOIL AND CLIMATE - VARY

20
Brainstorm paper Why is complex, highly
developed, expensive machinery not good for use
in an underdeveloped country?
