  3. 3. Terms to Know, Cont’d. • • • • Quality of Life Seasoning Swine Synthetic Fibers
  4. 4. What is Quality of Life? • Quality of Life includes adequate supplies of basic needs like food, clothing and shelter. • Agriculture provides each of these things. • Americans spend only about 11% of their total income on food, leaving more money than many others for clothing, housing and entertainment.
  5. 5. International Trade • International Trade is buying and selling commodities by two or more nations. Commodities are either imported or exported.
  6. 6. Exports • Goods sold to or in another country are exports. • Agriculture exports include corn, rice, soybeans, wheat, poultry and cotton.
  7. 7. Imports • Imports are products bought from another nation. Imports include bananas, cocoa, vanilla, shrimp and coffee.
  8. 8. Agriculture’s role in Human Nutrition • MyPlate was developed by the United States Department of Agriculture. It is made up of nutritional groups, which are the main types of food recommended for consumption.
  9. 9. Factors affecting healthy food choices include: • • • • Age Activity Level Gender Body Size
  10. 10. Agricultural Products for Food • Grain - grains are grown throughout the U.S., with the greatest production region in the mid-west. • Grains are used for bread, pasta, rice, cereal and many other food products. • Wheat and rye are two important grains.
  11. 11. Citrus • Citrus - grown in California and Florida, and imported from Mexico and South America. • Citrus includes: oranges, grapefruits, tangerines, tangelos, lemons and limes.

  13. 13. Cranberries • Cranberries are widely grown in New England.
  14. 14. Apples • Apples are grown in Washington, New York, Michigan and California. • About half of the apples produced are marketed fresh and the rest are processed into juice, jellies, pies and other products.
  15. 15. Vegetables • Cool weather crops, such as lettuce and broccoli, are grown in northern states in the summer and southern states during the winter. • Most warm weather vegetables are grown in California and Florida. • Many vegetables consumed in the U.S. are imported from South America and Mexico.
  16. 16. Milk • • • • Dairy Foods are made from milk. Most milk comes from cattle on dairy farms. Another source of milk is from goats Leading milk production states are California and Wisconsin.
  17. 17. Meat - Poultry • Poultry includes any domesticated birds raised for food. • The most popular poultry are chickens followed by turkey. • Chickens also produce most of the eggs in this country.
  18. 18. Meat - Beef • Beef is meat from cattle. It is prepared into popular dishes like steak and hamburger.

  20. 20. Meat - Aquaculture • Aquaculture is the production of aquatic plants and animals for food. • Fish are being farmed in oceans, streams, lakes, ponds and raceways. • Fish are harvested, processed, and prepared for the fresh or frozen market.
  21. 21. Meat - Lamb • Lamb refers to meat from a sheep that is less than a year old. • Mutton refers to meat that is from a sheep that is over a year old. • Compared to beef, chicken and pork, Americans consume little lamb and mutton.
  22. 22. Nuts
  23. 23. Agricultural products used to provide clothing • Clothing is made from natural and synthetic fibers. • A natural fiber is from a plant or animal. • A synthetic fiber is made from petroleum and other substances.
  24. 24. Cotton • A shrublike plant, cultivated as an annual. • Requires long growing season, warm temperatures. • Leading production states include California, Texas, Arizona and the lower southeast.
  25. 25. Flax • Produces fibers used in making a high quality cloth, called linen. • Flax plants require climates with plenty of rain, and moderate temperatures. • Most of today’s flax is grown in Europe and New Zealand.
  26. 26. Kenaf • Kenaf is a relatively new crop used to make cloth and paper. • From Africa. • Grows quickly; 12’-14’ in as little as 4-5 months.
  27. 27. Jute is used to make Burlap
  28. 28. Hemp and Sisal • Are coarse fibers used to make rope, rugs
  29. 29. Wool and Fur
  30. 30. Petroleum
  31. 31. Synthetic Fibers • • • • Made from petroleum. Tend to be more wrinkle resistant and durable. Cannot match the comfort of natural fibers. Today, cloth is generally a blend of each.
  32. 32. Agriculture Provides Shelter
  33. 33. What is Forestry? • Forestry is the science of planting, caring for and harvesting trees. • In the USA, there are 736.7 million acres of forested lands.
  34. 34. Forestry Products • Are grouped by the types of trees harvested. • Two major types of trees are hardwood, and softwood. • Hardwood trees are deciduous – they shed their leaves during the winter. • Softwood trees are conifers – evergreen trees, usually bearing cones and needles.
  35. 35. Hardwood - Deciduous
  36. 36. Conifers - Softwood
  37. 37. Lumber • Is made from sawing logs into boards. Logs are the large stems of trees that require many years to grow. • Trees are felled (cut down) and cut into log lengths – usually 12 – 20 feet in length. • Are cut, while green, into boards, for seasoning – the natural or artificial drying of lumber.
  38. 38. Lumber
  39. 39. Paper
  40. 40. Paper 1. Pulp is screened and washed. 2. The mixture of pulp and water is spread over a mesh wire to drain. 3. The remaining mat of fibers is then rolled and dried. 4. The fibers bond together during the drying process.
