Objective One
Define Quality of Life
Quality of Life
Having
adequate supplies of the
basic needs of food, clothing and
shelter
The ag industry provides the food
and fiber required by people
Agriculture allows people to enjoy a
higher quality of life
Quality of Life
Americans
spend 11% of their
total income on food
People spend 70% in some
other countries
Agriculture allows Americans to
spend more money on clothing
shelter, and entertainment
International Trade
American
agriculture helps
provide food and fiber for many
people in other countries
International trade is the buying
and selling of commodities by
two or more nations
Exports
Exports
are goods sold to another
country
Corn, soybeans, and wheat are
examples of important American
agriculture exports
The success of American
agriculture is largely dependent on
its exports
Imports
Commodities
bought from other
countries are called imports
Major American imports are
bananas, coffee, shrimp, and
vanilla
Good
jobs help people enjoy a
better quality of life as well
The American agriculture industry
provides jobs for about 16 out of
every 100 people.
This is higher than any other
industry in the country
Objective Two
Discuss Modern
Agriculture’s Role in Basic
Human Nutrition
What Role Does Agriculture
Play In Basic Human
Nutrition?
 Today,
one American farmer feeds over
130 people
 Consumers have a year-round, wide
variety of inexpensive, quality foods to
choose from
 We don’t always make nutritious
choices
Food Guide Pyramid
 Helps
people make healthy eating
choices
 Contains 5 nutritional groups
 Recommends types of foods from each
group for healthy consumption
 Nutritional fact labels must also be
present on all processed food products
Five Nutritional Groups
Breads
Fruits
Vegetables
Milk
Meat
Other Factors Effecting
Healthy Eating Choices
Your
Age
Your Activity Level
Your Gender, and
Your Body Size
Objective Three
List Ag Products Used To
Provide Food
What Ag Products Provide
Food?
Grains
Fruits
Vegetables
Milk
Meat
Nuts
Grain Crops
 Grains
are grown throughout the U.S.
 The largest region of production is in the
Midwest
 Grains are used for bread, pasta, rice,
cereal, and many other food products
 Wheat,
rye, and corn are examples
of grains
Fruits
Citrus
(grapefruit, oranges,
tangelos, lemons, limes) are grown
in Florida, California, or imported
Blueberries are grown in Michigan
Apples are grown in many states
Fruits are sold fresh or as
processed juice
Vegetables
Cool
weather vegetables (like
lettuce and broccoli) are grown
in northern states in summer
and southern states in winter
Many vegetables are imported
from South America and Mexico
Milk
Dairy
foods are processed from
milk
Most milk comes from cattle on
dairy farms
Another source of milk is goats
California and Wisconsin are
leading dairy producing states
Meat
Includes
poultry
Beef
Pork
Fish,
and
Lamb
Poultry
Poultry
Includes domesticated
birds grown for food
Chicken is most popular
followed by turkey
Chickens also produce most of
the eggs consumed in the
country
Beef
Beef
is meat from cattle
Steak and hamburger are
popular beef dishes
Pork
Pork
is meat from swine
Swine is a term to describe
hogs and pigs
Pork chops, bacon, and
sausage are popular pork
dishes
Fish
Aquaculture
is the term used to
describe the production of fish and
other aquatic plants and animals
Fish are farmed in the ocean,
ponds, raceways, and tanks
Fish are harvested, processed and
sold either fresh or frozen
Lamb
Lamb
refers to meat from sheep
less than a year old
Mutton is from sheep that are over
a year old
Compared to beef, pork and
poultry, Americans consume
relatively little lamb and mutton
Nuts
Each
year, about 430,000 tons of
nuts are produced in the United
States
The four major types of nuts
produced are almonds, pecans,
walnuts, and filberts
Objective Four
List Ag Products Used For
Clothing
Clothing is Made From
Natural and Synthetic Fiber
Natural
fiber comes from plants
and animals
Synthetic fibers are
manufactured from petroleum
and other substances
Examples of Natural Fibers
Cotton
Flax
Kenaf
Jute
Hemp
and Sisal
Wool and Fur
Cotton
Cotton
is a perennial plant that is
grown as an annual
Cotton requires a long, warm
growing season
Top cotton producing states are
California, Texas and Arizona
 Cotton
is picked by large machines that
remove the lint from the bolls
 The cotton is taken to the gin to remove
the seeds
 Seeds are used for cooking oil or
livestock feed
 Lint is pressed, graded, and milled into
cloth
Flax
Flax
plants produce fibers used in
making high quality cloth called
linen
Flax requires a rainy and warm
climate
Minnesota, North and South
Dakota grow substantial amounts
of flax
 Flax
plants grow about three feet tall
 Linen comes from the fibers that make
up the phloem of the plant
 Fibers are rolled and later combed to be
spun into yarn
 Flax seed is used to make linseed oil for
paints and varnishes
Kenaf, Jute, Hemp and
Sisal
Kenaf
is a relatively new plant that
is used to make cloth and paper
Jute plant fiber is used to make
burlap
Hemp and Sisal are coarse fibers
used to make rope
Wool and Fur
 Sheep
and goat fleece are sheared,
cleaned, dyed, and woven into threads
 Angora goat fleece is woven into mohair
 Fur is used to produce hats, coats, and
other clothing. Rabbit and mink are two
examples of fur used in clothing
Synthetic Fibers
Rayon,
nylon and polyester fibers
are processed from petroleum
products
Synthetic fibers are more durable
and wrinkle less than natural fiber
Natural fiber is more comfortable
Cloth today is often a blend of both
natural and synthetic fiber
Objective Five
List Ag Products Used For
Shelter
Forestry
Forestry
involves planting, caring
for, and harvesting trees
There are about 736 million acres
of forest land in the United States
Products like plywood, particle
board, veneer, and paper are used
for shelter
Hardwood and Softwood
Trees
Hardwood
trees are deciduous-they lose their leaves in the fall
Softwood trees are conifers.
Conifers are evergreen trees that
have cones and needles rather
than leaves
 Trees
are felled (cut down) and cut into
log lengths of 12 to 20 feet
 At the saw mill, logs are cut into boards
and graded
 Lumber is cut while still green
 Lumber must be seasoned. Seasoning
is the natural or artificial drying of the
lumber
 Natural
drying involves allowing air to
circulate around and through stacks of
lumber
 Artificial drying uses heat and is faster
 Lumber is smoothed and sized. Planing
involves removing the roughness left
from sawing
Paper
 Smaller
trees are used for paper
 Wood is broken into small pieces and
soaked in a chemical bath to make pulp
 Pulp is screened, washed and drained
 Fibers are then rolled and dried
 Fibers bond together during drying
