2. What is it? -The farms that uses pesticides & non organic fertilizers -Grows only one kind of crop (monoculture)

3. Problems: -Wind erosion -Water erosion -Water Contamination -Monoculture

4. Solutions: -Add wind breaks to lessen wind erosion -Improve drainage in the field -Use contour ploughing -Use of cover crops -Use of natural predators

5. Affects on the Lithosphere: No diversity => Loss of nutrients Use of pesticides infiltrates & poisons land => loss of more nutrients Deforestation

6. Affects on the Atmosphere: -Pesticides may be lost in atmosphere through evaporation

7. Affects on the Hydrosphere: -Disrupts the hydrological cycle -Pesticides contaminate local water sources & ground water

8. Affects on Biosphere: -Kills animals that eat plants sprayed w/pesticide

9. Poorly Managed Brazil millions of trees cut for farming & agriculture Farms built on soil with few nutrients => Soil deteriorates quickly

11. Organic Agriculture Composting & Mulching Composting & Mulching Promoting local / wild flora and fauna Promoting local / wild flora and fauna Influence of natural fertilizer Influence of natural fertilizer no pesticide use (biocides or natural predators no pesticide use (biocides or natural predators

12. Lithosphere Organic fertilizer use increases the fertility of soil and humus Organic fertilizer use increases the fertility of soil and humus Crop rotation decreases soil erosion Crop rotation decreases soil erosion – maintaining soil structure No pesticide use means increase soil nutrients No pesticide use means increase soil nutrients Impact

13. Hydrosphere Improved irrigation practices maintain water quantity Improved irrigation practices maintain water quantity No pesticides create less contamination of groundwater No pesticides create less contamination of groundwater

14. Atmosphere No pesticides spray drift leave air clean No pesticides spray drift leave air clean

15. Biosphere No pesticides use on crops = Less illness of human and animals No pesticides use on crops = Less illness of human and animals Healthier food is consumed Healthier food is consumed

16. Solutions Restoration of farm lands to their natural order – –sustain natural livestock – –replanting natural plants – –crop rotation Hydroponics – –crop production that occurs inside large greenhouses
