Ecological Impacts
Potential ecological impacts of industrial crop production:
● Soil erosion● Decrease in bee populations● Emergence of pesticide-
resistant weeds● Aquatic dead zones● Depletion of phosphorous
and fossil fuels● Depletion of groundwater
The 1930s Dust Bowl demonstrated the devastating potential of soil erosion. See the Crop Production primer for details. Photo credit: NOAA, 1935. Public domain.
