What is Agriscience?Agriscience is the application
of scientific principles to agriculture.
3 Basic Areas of AgriscienceBiology- The study of living
thingsChemistry- Deals with
elements and simple substances
Biochemistry- Focuses on chemistry as it is applied over living things.

What is Agriscience?Application of scientific
principles and new technologies
Applied scienceUses basic sciences in
practical ways Biology Chemistry Physics
Technology- The application of science to an industrial or commercial purpose
High Tech- The use of electronics and state-of-the-art equipment to perform task

What is the definition of Agriculture?Agriculture also called farming or
husbandry is the production and cultivation of animals, plants, fungi, and other life forms for food, fiber, biofuel and other products used to sustain life.
Agriculture was the key development in the rise of sedentary human civilization, whereby farming of domesticated species created food surpluses that nurtured the development of civilization.
The study of agriculture is known as agricultural science.

What is Agriculture… Continued!Agriculture is also known as the activities
concerned with the production of plants, animals, and related supplies, mechanics, products, processing, and marketing.Production agriculture (farming) only accounts
for 1/5th of the total agriculture jobs in the US

Fact:A United States Department
of Agricultural study forecast that job opportunities for graduates in agricultural and life sciences will exceed the graduates available in the coming years.

What is Agribusiness? Refers to commercial firms that have
developed out of agriculture Take a moment to name three agribusinesses
in your notes: John Deere Monsanto Tractor Supply

How important is agricultural trade to the U.S. economy?The United States is now the world’s
largest agricultural exporter. The value of agricultural exports equals nearly one-fourth of farm cash receipts, about twice the level of the overall U.S. economy, and 1 out of 3 acres are planted for export.
![Page 19: What Is Agriculture? Why Is It Important?](https://reader035.fdocuments.net/reader035/viewer/2022062400/568168f0550346895ddff56a/html5/thumbnails/19.jpg)
How much of its agricultural products does the United States export?American farmers export:
45 percent of their wheat34 percent of their soybeans71 percent of their almondsMore than 60 percent of their
sunflower oil.

What would happen if US Agricultural Production stopped today?In 3-5 days: The American economy would begin
to collapse.Most American homes do not have enough food to
last more than 3 days and not enough water on hand for more than 1 day. Economic Example: Stock markets crashed after 9/11,
driven by “the mood” (fears and confidences) of the public.
Emergency Example: Hurricane Katrina- Riots, looting, grocery stores bare in a matter of hours.

What would happen… Continued.In 5 -7 days: The entire World would begin to
suffer the same economic collapse.Humanitarian aid to 3rd World or war torn countries
would have stopped completely.Northern European countries that rely on
imports from America would begin to suffer a food shortage. Finland, Sweden, Norway:
No fruit? No meat? No veggies?
