Define Quality of Life

Objective One

Quality of life?

Which standard would you prefer?

Quality of LifeHaving adequate supplies of the basic needs of food, clothing and shelter.

The Agriculture industry provides the food and fiber required by people.

Agriculture allows people to enjoy a higher quality of life.

Americans spend 11% of their total income on food.

In other countries people spend well over 80% of income on food.

Agriculture allows Americans to spend more money on clothing shelter, and entertainment.

Quality of Life

Compare our Food Dollar to other Countries!

International TradeAmerican 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.

ExportsExports are goods sold to another country.

Corn, soybeans, rice and wheat are examples of important American agriculture exports.

The success of American agriculture is largely dependent on its exports.

ImportsCommodities bought from other countries are called imports.

Major American agricultural 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 in our country.

This is higher than any other industry in the country.

Discuss Modern Agriculture’s Role in Basic Human Nutrition

Objective Two

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.

List Ag Products Used To Provide Food

Objective Three

What Ag Products Provide Food?GrainsFruitsVegetablesMilkMeatNuts

Grain CropsGrains are grown throughout the U.S.The largest region of production is in the

MidwestGrains 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 MichiganApples are grown in many statesFruits are sold fresh or as processed juice

VegetablesCool 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

MilkDairy 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. New Mexico quite often leads the nation in the amount of milk produced per cow!

MeatIncludes poultryBeefPorkFish, andLamb

PoultryPoultry Includes domesticated birds grown for food.

Chicken is most popular followed by turkey.

Chickens also produce most of the eggs consumed in the country.

Poultry consumption increases in the U.S.

BeefBeef is meat from cattleSteak and hamburger are popular beef dishes

PorkPork is meat from swine.Swine is a term to describe hogs and pigs.

Pork chops, bacon, and sausage are popular pork dishes.

FishAquaculture is the term used to describe the production of fish and other aquatic plants and animals

Fish are farmed in the ocean, ponds, and tanks.

Fish are harvested, processed and sold either fresh or frozen.

LambLamb 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.

NutsEach 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

New Mexico is one of the top two states in pecan production.

List Ag Products Used For Clothing

Objective Four

Clothing is Made From Natural and Synthetic Fiber

Natural fiber comes from plants and animals. ( mostly wool and cotton )

Synthetic fibers are manufactured from petroleum and other substances

Examples of Natural FibersCottonFlaxKenafJuteHemp and SisalWool and Fur

CottonCotton 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

FlaxFlax 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 FurSheep 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.

List Ag Products Used For Shelter

Objective Five

ForestryForestry 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 TreesHardwood 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 greenLumber 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

PaperSmaller 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.
