- 2. Type of commercial fishing using weighted nets that are drug along the bottom
- 3. Heating ore with chemicals to extract metals
- 6. Type of forestry where rows of trees are cleared to reduce erosion
- 7. Confined feet lot operation which fattens up livestock to decrease time to slaughter
- 11. Surfaces such as concrete and pavement where water quickly accumulates and runs off
- 12. Type of recycling were the resource is turned back into the same resource
- 13. Type of grazing and cultivation where animals and crops are rotated to reduce negative impacts
- 15. Shared resources among many people/communities
- 16. Water from rain or irrigation moving over the surface of land carrying soil and pollutants
- 17. Cutting all trees in a designated area
- 18. Genetic modifications to increase yields/resistance to pests, drought, etc.
- 19. Type of fertilizer such as manure or compost that is not composed of man made chemicals
- 22. Effect of city surface that cause them to have a higher temperature than the surrounding area
- 24. Type of commercial fishing used close to shore to catch fish by the gills
- 25. Chemical compounds that target crop pests such as insects and worms
- 26. Irrigating crops through a large rotating arm with adjustable sprayers
- 30. Type of mining where extensive tunnels are used
- 32. Type of CAFO where fish are grown in pens or tanks
- 33. Surfaces such as gravel and specialized concrete where water will infiltrate and be absorbed to reduce runoff
- 36. Turning of grassland to desert due to overgrazing
- 37. Type of grazing where cattle are free to range over a wide area of land
- 40. Increasing salt content of soil from high evaporation rate of irrigation water
- 42. Type of forestry where only diseased and other selected trees are cut in an area to decrease density
- 43. Roofs and walls that are covered with live plants to increase air and water filtration and reduce runoff and heat in cities
- 44. Type of commercial fishing targeting specific schools of fish near the surface
- 45. Type of mining where all soil and vegetation is removed on the surface
Down
- 1. The use of resources in a way that will not deplete them or cause environmental harm
