Importance Of Agriculture
To Society
Student Objectives
 Define
quality of life
 Discuss agriculture’s role in basic
human nutrition
 List ag products used to provide food
 List ag products used for clothing
 List ag products used for human shelter

Objective One
Define Quality of Life
Quality of Life
adequate supplies of the
basic needs of food, clothing and
The ag industry provides the food
and fiber required by people
Agriculture allows people to enjoy a
higher quality of life
Quality of Life
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
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
are goods sold to another
Corn, soybeans, and wheat are
examples of important American
agriculture exports
The success of American
agriculture is largely dependent on
its exports
bought from other
countries are called imports
Major American imports are
bananas, coffee, shrimp, and
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
 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
Food Guide – My Plate
 Helps
people make healthy eating
 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
Other Factors Effecting
Healthy Eating Choices
Your Activity Level
Your Gender
Objective Three
List Ag Products Used To
Provide Food
What Ag Products Provide
Grain Crops
 Grains
are grown throughout the U.S.
 The largest region of production is in the
 Grains are used for bread, pasta, rice,
cereal, and many other food products
 Wheat,
rye, and corn are examples
of grains
(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
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
foods are processed from
Most milk comes from cattle on
dairy farms
Another source of milk is goats
California and Wisconsin are
leading dairy producing states
Includes domesticated
birds grown for food
Chicken is most popular
followed by turkey
Chickens also produce most of
the eggs consumed in the
is meat from cattle
Steak and hamburger are
popular beef dishes
is meat from swine
Swine is a term to describe
hogs and pigs
Pork chops, bacon, and
sausage are popular pork
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
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
year, about 430,000 tons of
nuts are produced in the United
The four major types of nuts
produced are almonds, pecans,
walnuts, and filberts
Objective Four
List Ag Products Used For
Clothing is Made From
Natural and Synthetic Fiber
fiber comes from plants
and animals
Synthetic fibers are
manufactured from petroleum
and other substances
Examples of Natural Fibers
and Sisal
Wool and Fur
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
plants produce fibers used in
making high quality cloth called
Flax requires a rainy and warm
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
is a relatively new plant that
is used to make cloth and paper
Jute plant fiber is used to make
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
nylon and polyester fibers
are processed from petroleum
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
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 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
 Natural
drying involves allowing air to
circulate around and through stacks of
 Artificial drying uses heat and is faster
 Lumber is smoothed and sized. Planing
involves removing the roughness left
from sawing
 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
