| 9670418575 | Undernutrition | Not consuming enough calories to be healthy. |  | 0 |
| 9670418576 | Malnourished | (3 billion, 1/2 of population). Having a diet that lacks the correct balance of proteins, carbohydrates, vitamins and minerals; Regardless of calories, |  | 1 |
| 9670418579 | Famine | Condition in which food insecurity is so extreme that large #'s of deaths occur in a given area over a relatively short period. |  | 2 |
| 9670418580 | Anemia | - Iron deficiency; is the most widespread nutritional deficiency in the world. (Est. 3 billion); caused by lack of iron in food, also AIDS, malaria and parasite infestations |  | 3 |
| 9670418581 | Overnutrition | The ingestion of too many calories and improper foods, which causes a person to become overweight (Est. 1 billion). |  | 4 |
| 9670418582 | Meat | 2nd largest component of the human diet is usually defined as livestock and poultry. |  | 5 |
| 9670418586 | Green Revolution | A shift in agricultural practices in the 20th century that included new management techniques and mechanization as well as the triad of fertilization, irrigation and improved crop varieties. These changes increased food production drastically. |  | 6 |
| 9670418588 | Waterlogging | When soil remains under water for prolonged periods and impairs root growth because roots can't get oxygen. |  | 7 |
| 9670418589 | Salinization | Occurs when the small amounts of salts in irrigation water become highly concentrated on the soil surface through evaporation. Can reach toxic levels and impede plant growth. |  | 8 |
| 9670418590 | Organic Fertilizers | Composed of organic matter from plants and animals, naturally occurring. Manure, etc. Agriculture removes organic matter and nutrients so fertilizer replaces the nutrient levels to help with crop growth. |  | 9 |
| 9670418591 | Synthetic Fertilizers | Same as inorganic fertilizer; Produced commercially. Nitrogen fertilizers are often made by combusting natural gas. |  | 10 |
| 9670418592 | Inorganic Fertilizers | Same as synthetic fertilizer; Composed of simple chemicals and minerals; good but can take a lot of energy to produce (like Nitrogen fertilizers) | 11 | |
| 9670418593 | Monocropping | Dominant agricultural practice in the U.S. Where large patches of land grow only one kind of crop. (like wheat and cotton); it has improved agricultural productivity but leads to soil degredation |  | 12 |
| 9670418594 | Pesticides | Substances, either natural or synthetic, that kill or control pests. |  | 13 |
| 9670418595 | Insecticides | Pesticides that target species of insects and other invertebrates that eat crops. |  | 14 |
| 9670418596 | Herbicides | Pesticides that target plant species that compete with crops. |  | 15 |
| 9670418597 | Broad-Spectrum pesticides | Pesticides that kill many different pests. | 16 | |
| 9670418608 | Intercropping | 2 or more crop species are planted in the same field at the same time to promote a synergistic interaction between them. Ex. corn needing lots of nitrogen is planed with peas that produce nitrogen. |  | 17 |
| 9670418609 | Crop Rotation | Moving crops around to help keep nutrient levels high throughout the years; produces same effect as intercropping. Ex. peas planted leaving nitrogen, then corn planted which needs lots of nitrogen |  | 18 |
| 9670418611 | Contour Plowing | Plowing and harvesting parallel to the topographic contours of the land helps prevent erosion by water. |  | 19 |
| 9670418612 | No-Till Agriculture | Agricultural method in which farmers do not turn said between seasons; avoid soil degradation / erosion that comes with conventional agricultural techniques. |  | 20 |
| 9670418613 | Integrated Pest Management (IPM) | An agricultural practice that uses a variety of techniques designed to minimize pesticide outputs; Ex. crop rotation + intercropping + pest resistant crops... |  | 21 |
| 9670418614 | Organic Agriculture | Production of crops without the use of synthetic pesticides or fertilizers. |  | 22 |
| 9670418620 | Aquaculture | Farmings of aquatic organisms like shellfish, fish or seaweed; ex. US catfish, trout, shrimp and salmon raised this way. |  | 23 |
