Explain three ways to use forests more sustainably that emphasize their ecological services
Flood control Strip Cutting No fragmentation, we don’t want to break up the forest, we want to cut in a line and not disturb the ecosystems as much as possible Leave dead stuff (Decompose and continue the nutrient cycle and will provide habitats Leave Old growth forest alone because we have a lot of land we are already using for timber (Old growth has a lot more biodiversity than other forest)
Explain why a farmer would rotate corn crops with soybean or alfalfa crops
Corn uses a lot of nitrogen legumes like soybeans replace the nitrogen and allow you to use less fertilizer, keep the land covered with vegetation to reduce erosion Less affected by corn pests and disease, reducing pressure on corn

Compare and contrast the flood irrigation method to the drip irrigation method
Flood Irrigation “Farmers flow water down small trenches running through their crops.” -Large-scale -Less conservative with water usage -Cheapest -Best for environment that needs quick and extensive watering Drip irrigation Precise, delivery to individual plants Conserves more water, Better for moisture sensitive crops -Expensive More efficient
Explain why mountaintop removal causes more environmental damage than most other forms of mining
Mountaintop removal process - Blast mountaintops - Broken mountaintop is then shifted into valleys and fills below - They collect the ore (Ore can be retrieved 400 feet or deeper) - Leave flat terrain (plant non-native species of grass or other vegetation) (hydroseeding More negative b/c -Coal deposits, shuve everything but the coal of the side of the mountain, destroying The vegetation on the side (causes more erosion and habitat loss) -Change to river flow, toxics are then put into the water and carried to next habitat (further down stream)
