Our Shared Living Environment Habitable regions Balance required Plants, animals, insects, soil, water, and air Humans Excessive populations can damage plants Only organisms able to improve living environments

Our Shared Living Environment (cont’d.) Animals Excessive populations can damage plants In high numbers, compete excessively with humans Plants Generally beneficial Excessive growth infringes on humans/animals Moved text down

Agriscience in Our Growing World Science of food production, processing, and distribution Holds keys to prosperous future Accounts for 14% of U.S. jobs Facilitates high standards of living

Agri-Profile Career area: environmental management Specialists in air and water quality, soils, wildlife, fire control, automotive emissions, and factory emissions Work can be indoors or outdoors, urban or rural settings; or in boats, planes, laboratories, parks, etc. Global significance: hunger and pollution

Changing Population Patterns More population growth More children are surviving to adulthood Adults are living longer Largest age group Previously under 25 years old

Changing Population Patterns (cont’d.) Graphs: age profiles in developed countries Honduras: pyramid-shaped Canada: narrow bottom cone Sweden: column China: impact of 4-2-1 policy Comp: I moved the text down to fix the crash between the head and the first bulleted line of text.

Impact of Agriscience Progress through agricultural engineering Mechanization “Necessity is the mother of invention” Electricity in rural areas

Impact of Agriscience (cont’d.) American inventors Cyrus McCormick: reaper Thomas Jefferson: iron plow Eli Whitney: cotton gin Edmund W. Quincy: corn picker Joseph Glidden: barbed wire Anna Baldwin: milking machine Benjamin Holt: tractor

Impact of Agriscience (cont’d.) Formation of machinery companies Early 1900s Improvements to successive inventions U.S. agriculture: significant expansion Mechanizing undeveloped countries Simple, tough, and reliable machines

Impact of Agriscience (cont’d.) Improving plant and animal performance Loosened soil; planted seeds Kept animals away until after harvest Mechanization of agriculture: contributed to larger farms; freed many to learn other trades

Bio-Tech Connection Agriscience and biotechnology Continuation of life: ornamental horticulture; food supply; tree products Modified animal species Increased productivity Genetic engineering Expanding modern technology throughout the world

Impact of Agriscience (cont’d.) Improving life through agriscience research George Washington Carver: 300+ uses for the peanut Soybeans: legumes—protein source; tofu; soy oil Potatoes: resistant to diseases and insects Turkeys: smaller breeds The Green Revolution AU: Okay to say that potatoes are resistant to diseases and insects? Change “resistant” to “resistance”? Inserted closed em dash between legumes and protein

Impact of Agriscience (cont’d.) Improving life through agriscience research Cultivated blueberries Nutritional values: accurate determination Biological attractants: insect trapping Recent breakthroughs Rot-resistant tomato Natural rubber production Bioengineered designer foods I removed the hyphen from bioengineered.

Hot Topics in Agriscience Genetically modified foods Selective breeding Genetic engineering: improvements versus controversy Spelled out versus

Impact of Agriscience (cont’d.) Recent breakthroughs Genetic engineering Goat’s milk: monoclonal antibodies Biodiesel from animal fat Dairy cows: mastitis reduced Human nutrition: research-based recommendations I removed the hyphen from Biodiesel.
